1Welcome to ArcView GIS Version 3.1. Whether youre an experienceduser or just getting started with ArcView GIS software, this guide willintroduce you to the new features and capabilities available in the ArcViewGIS Version 3.1 release.

This release demonstrates the commitment of ESRI to enhance yourexperience with ArcView GIS by introducing a wizard-based approachtoward a variety of sophisticated tasks such as advanced map productionand advanced geoprocessing. These wizards, along with other interfaceupdates, leverage more of the power of ArcView GIS to help you quicklyand easily accomplish your GIS objectives.

ArcView GIS Version 3.1 also continues to expand your GIS capabilitiesby not only updating the existing suite of ArcView GIS extensions, butalso by introducing several exciting new extensions specifically designedto supplement your GIS requirements. In particular, ArcView GIS nowfeatures a Report Writer extension that enables you to easily generateprofessional reports, including embedded maps and charts, that help youmore successfully communicate the results of your GIS analysis.

Also included are significant updates to the ESRI Data & Maps CD, whichnow, for the first time, also includes new data sets specifically for Europe.

This guide describes the new features and capabilities introduced forArcView GIS Version 3.1. For a complete description of the other featuresof ArcView GIS, please refer to the ArcView GIS user guide, UsingArcView GIS, and online help.

Whats new in ArcView GIS Version 3.1 3

Application levelStartup Screen dialogCreated with new users in mind, this dialog gives quick and easy access to some of themost common tasks performed when first starting ArcView GIS. You can choose to createa new project (either blank or with a view) or to open an existing one. Clear the checkbox to stop the dialog from displaying when ArcView GIS opens.

If you want the dialog displayed again, delete the avstart.txt file in your TEMP directory(PC) or $HOME directory (UNIX).

Project update for existing projectsWhen opening a project that has a customized interface (that is, the project uses one ofESRIs optional extensions, or contains changes to buttons, tools, or menus through theuse of the Customize dialog box) and was created using ArcView GIS Version 3.0 or3.0a, ArcView GIS will show the following message box:

To update your project, click Yes. The new Version 3.1 tools will be added to yourinterface. To leave your project as is, click No. Your project will not be updated.


Expanded date supportThe supported range of the value of the Date class in ArcView GIS is no longer limited to1970 to 2038. ArcView GIS now supports a Date range from 4715 B.C. to 9999 A.D. Whiledates beyond this range may work, they may not produce consistent results for all Avenuerequests. For more information, refer to the Date (Class) topic in the ArcView GISonline help index.

ArcView GIS will recognize dates from January 1, 0000 to December 31, 9999, indBASE files and from January 1, 1000, to December 31, 9999, in INFO files. Datesoutside this range are given a value of null when retrieved from a table. Delimited textfiles store dates as strings that can be converted to dates with Avenue. This means thedelimited text file date range is the same as Avenue Date class range.

Improved support for ARC/INFO line symbolsPrior to Version 3.1, ArcView GIS could not display some types of ARC/INFO linesymbolsparticularly custom symbols, such as multilayer or LineType Marker. Nowmost ARC/INFO line symbols can be used in ArcView GIS.

New TrueType fonts and symbols

Version 3.1 includes new and enhanced symbol palettes.

Geology.avp: nearly 300 line and marker symbols for making U.S. Geological Survey(USGS) compliant geologic maps

Weather.avp: additional weather frontline symbols

Transp.avp: additional railroad line symbols

Forestry.avp: line and marker symbols for creating forest fire-fighting maps

Shown below are some of the new highway and railroad symbols that have been added tothe transp.avp palette file.


Import multilayer ARC/INFO line symbols

You can now import multilayer ARC/INFO line symbols into ArcView GIS. Even if youdo not have access to ARC/INFO, you can create your own symbols using new Avenueclasses added to support these new capabilities. For more information, refer to thesymbols, how to create complex line symbols using Avenue topic in the ArcView GISonline help index.

Import ARC/INFO LineType Marker symbols

You can also import LineType Marker and LineType VertexMarker from ARC/INFOsymbol sets. The ARC/INFO marker symbols you import must already be defined usingTrueType fonts. (This capability became available in ARC/INFO Version 7.1.) You willneed to create a new version of the TrueType font and name it appropriately so thatArcView GIS can match the information in the LineSet file and use the correct font andcharacter for your font.

If the ARC/INFO symbol was created using the older IGL font technology, ArcView GISwill still import the symbol, including all of its properties, except the marker symbol. Thecurrent default marker symbol in ArcView GIS will be used, but you can use Avenue tosubstitute one thats more appropriate. For script examples, refer to the symbols, Avenueexamples topic in the ArcView GIS online help index.

New ways to customize the ArcView GIS application

Tools directory added to $AVHOMEA directory called tools has been added to your $AVHOME directory. This directorycontains the following:

The extensions that load automatically when ArcView GIS starts (Startup Screendialog, Create Buffers wizard, Label and Text tools, Neatline button, Shape Propertiesdialog, and TOC Style). If you dont want an extension to load automatically, you canmove it to the $AVHOME\ext32 directorythe extension will then be visible in theExtensions dialog. This provides a new way for developers to deliver functionality inArcView GIS and load it automatically.

A bitmaps directory containing bitmaps used in the new interfaces that are based onDialog Designer dialogs.

Extension .apr files available

The $AVHOME\samples\ext directory contains the project files used to create theextensions listed above. You can customize the extensions by editing the project files andcreating new versions of the extensions.


ExtensionsArcView GIS extensions are add-on programs that provide specialized GIS functionality.When you load an extension, the ArcView GIS user interface changes to reflect thefunctionality available in the extension. Depending on the extension, new menus, buttons,tools, and dialog options will be available.

Extensions are loaded and unloaded using the Extensions dialog box. To access theExtensions dialog, choose Extensions from the File menu.

The following extensions are included with ArcView GIS Version 3.1:

CAD Reader extensionCAD Reader extension has been upgraded to support AutoCAD Release 14.x drawingand DXF files in ArcView GIS. The extension has also extended its 3D CAD drawingsupport to work with the ArcView 3D Analyst extension, allowing you to add 3D CADdrawings directly into 3D Analyst (similar to any other 3D themes) for analysis andinteractive perspective viewing.

Database Access extensionDatabase Access extension, Version 1.1, provides multiuser, client/server access to spatialand nonspatial data stored in relational databases. You can create database themes to seethe spatial data, and database tables to see the nonspatial data in ArcView GIS. Thisversion of the extension provides access to Spatial Database Engine (SDE) Version3.0.2 databases, which can include Oracle Spatial Data Option (SDO) layers. It alsoprovides an improved Structured Query Language (SQL) Query Wizard and severalperformance enhancements. The Database Access user guide is available as a .pdf file($AVHOME\avdocs\dbaccess.pdf).


Dialog Designer extensionDialog Designer extension provides Avenue developers with tools for customizing theArcView GIS interface. With this extension, you can create specialized input forms,organize related tools in separate dialogs, add buttons directly to your view or layout, andlink whats displayed to your data. The extension supports the display of symbols in listand combo boxes. Multiple rows and columns in a list box are also supported. TheDialog Designer user guide is included with ArcView GIS Version 3.1.

Digitizer extensionDigitizer extension has been enhanced to support stream mode digitizing. Using thismethod, you click only the first vertex and simply trace over the feature on a paper map.When you complete tracing the feature, you click another button to end the line. ArcViewGIS does the rest by automatically adding vertices based on a stream tolerance distancethat you specify in the current map units. Stream mode digitizing makes it quick and easyto capture complex features, such as streams, rivers, and contours, off the paper map.When you load the Digitizer extension, ArcView GIS adds two new choices to the Viewmenu: Stream Tolerance and Enable/Disable Stream Mode.

Stream Tolerance

When you trace features over the paper map in stream mode, ArcView GIS automaticallyadds vertices at a specified interval. You can set this interval in current map units andchange the distance at any time, even while tracing an existing line. You can also specifythe stream tolerance distance interactively using the Stream Tolerance tool in the toolbar. (The Stream Tolerance tool allows you to perform the same functions interactively asthe Stream Tolerance menu choice.)


Enable/Disable Stream Mode

This menu item allows you to switch between digitizing in point mode and the newenhanced method of digitizing in stream mode. The default option is point modedigitizing. You may also use the F3 function key to switch between the two modes.

For detailed information on how to digitize features in stream mode, refer to theDigitizers, Stream mode digitizing topic in the ArcView GIS online help index.

The Digitizer extension is not available on UNIX.

GeoProcessing extensionThe wizard-based interface in this extension lets you perform some new spatial analysisfunctions in ArcView GIS. To access the GeoProcessing extension, load the extensionusing the Extensions dialog. Make sure a view is open and active. Then, from the Viewmenu, choose GeoProcessing.

The following functions are provided:

Dissolve features based on an attribute

This process will aggregate features in a theme based on an attribute of that theme. Forexample, Dissolve could be used to create a theme showing sales regions by salesperson,where each salesperson is responsible for several counties. Sales territories could beestablished by removing shared county boundaries from those counties represented bythe same salesperson.


Merge themes together

This process will append two or more themes into one theme. The merge process willcreate a new theme using the fields from the theme you select. If the other themes youremerging have more fields than the theme you have specified, those fields wont be in thenew themes table. If the other themes dont have the same fields as the theme youvespecified, empty cells will be added to the new themes table. You might merge severaltiled county themes with census data to make a metropolitan area.

Clip one theme based on another

This process creates a new shapefile by using one theme (the clip theme) like a cookiecutter on another (the input theme). For instance, you might use a county boundary froma counties theme to clip a roads theme. This would create a new theme containing onlythe roads that fall inside the county boundary.

Intersect two themes

This process computes the geometric intersection of two themes and adds it to your viewas a new theme. The two spatial data sets are integrated, but only the features that fallwithin the spatial extent common to both themes are preserved. For example, supposeyoure a builder and want to build a retirement center within the city boundaries. Youwant to create a theme that assigns land use information (like building codes) to yourparcel data so you can look for areas meeting the requirements for multifamily dwellings.

Union two themes

The Union process creates a new theme by overlaying two polygon themes. The outputtheme contains the combined polygons and attributes of both themes. Suppose you wantto analyze the erosion potential of soils in a given area. Some combinations of slope andsoil type represent high risk for erosion and knowing where these conditions existenables risk assessment of crops. You have one theme with boundaries of slope andanother with soil type data. You use Union to create a new theme that contains the spatialcombination of information with attribute data, permitting evaluation of erosion potential.

Assign data by location

The assign data by location operation performs a spatial join between two selectedthemes. A spatial join is similar to an attribute join; however, it is based on the spatialrelationship between the features in the two themes. For example, a travel agencyconcerned about client safety might assign data from a theme of hotels in a major city toa theme of crime events. The hotel data would be added to the crime event data, alongwith the distance to the hotel nearest the crime event. As a result, the hotels nearest themost crimes may not be recommended to the travel agencys safety-conscious clientele.


Graticules and Measured Grids extensionGraticules and grids are used to show latitude and longitude on a reference map such as anavigational chart, regional map, or a topographic map. Using a set of easy-to-use wizardpanels, youll be able to create a grid, graticule, or both. If youre not satisfied with thebest-guess evaluation of ArcView GIS for settings, you can customize them yourself.

Customization options include the ability to show only graticule lines and labels or createa full or partial grid. There are also options for choosing the font style and size of yourlabels. The interval between graticule lines can be adjusted by changing the settings fordegrees, minutes, and seconds. If youre showing graticule lines, you can set the linewidth and color.

Like graticules, you can also adjust display settings for a measured grid. The gridinterval, again, is initially estimated by ArcView GIS, but you can choose to display yourgrid as tics or as a set of intersecting lines. Line width, color of grid tics and lines, as wellas font, font size, and style for labels can be adjusted as desired. Border options,including line color and style, are also available.

To access the Graticules and Measured Grids extension, load the extension using theExtensions dialog. You must have at least one view frame in your layout before theGraticules and Measured Grids extension is enabled. Click the Graticule and MeasuredGrids button on the ArcView GIS tool bar to display the first wizard panel.

ERDAS IMAGINE Image extensionThis extension provides support for ERDAS IMAGINE images. In this version ofArcView GIS, the extension was upgraded to use ERDAS IMAGINE 8.3.1 libraries onthe PC and the 8.3 libraries on UNIX.


JPEG (JFIF) Image Support extensionThis extension provides support for JFIF images, the public domain image file format forJPEG compressed images.

Legend Tool extensionThis extension allows you to create a custom graphical legend in a layout using a set ofuser-friendly wizard panels. You can create a legend for any view in your project, choosewhich themes you want shown, and select how many columns to use to display symbolsand labels. Other panels allow you to change legend titles, choose settings for legendborders, designate how legend symbols are represented, and set the spacing betweenlegend elements. You can preview your legend at any time. This extension is derived fromthe previous sample extension, MapTools.

To use the Legend Tool, select the Legend Tool extension from the Extensions dialog.The Legend tool will appear on the tool bar once you have a layout that containsone or more views. Click the Legend tool, then the layout.


Military Data Reader extensionsThe Military Data Reader extensions allow ArcView GIS to recognize a variety of imagedata formats, typically of interest to the defense/intelligence community, as direct readimage data sources. No translation is required to use these image data sources. Once theproper extension for each image format is loaded, you can use these image data sourceswith ArcView GIS like any other supported image data source. The Military Data Readerconsists of multiple extensions that you can use in any combination. These extensionsinclude support for the following formats:

ARC Digitized Raster Graphics (ADRG Image Support extension) Compressed ARC Digitized Raster Graphics (CADRG Image Support extension) Controlled Image Base (CIB Image Support extension) National Image Transfer Format (NITF Image Support extension)

MrSID Image Support extensionMrSID is a multiresolution wavelet-based image format that allows a high compressionratio and fast access of large amounts of data at any scale. Support for the MrSID imageformat was added as an example of using the ImgDLL class that allows image formats tobe added to ArcView GIS. When you load the MrSID Image Support extension, you canadd .sid files to views as image themes.

Report Writer extensionThe Report Writer extension integrates the industry-leading Crystal Reports report-generating and editing application with the existing ArcView Table, View, and Projectuser interface. The goal of the ArcView Report Writer interface is to streamline theprocess of data selection and preparation for the reporting process. ArcView GISprovides a Report wizard that lets you choose the type of report you want, choosewhether you want to use all the records in the table or only the selected records, andspecify the output report name. Then the Report wizard will start the Seagate CrystalReports application with your data already loaded so you can easily continue designingyour report.


With the ArcView Report wizard, you can choose one of the following report types:

Quick Report Standard Report

Form Letters

Mailing Labels

Top Number (N) Report Cross Tab Report

Drill Down Report

A report based on another template

Note: If you do not have Seagate Crystal Reports installed on your system, you can stillcreate a simple report with ArcView GIS using Quick Reports. The Quick Reports optiondoes not use Seagate Crystal Reports and is available after any installation of ArcViewGIS. The Quick Reports interface provides basic tools for selection and organization offields; setting fonts, column width, and row heights to be used in the report; andpreviewing and printing the report.

The Report Writer extension is not available on UNIX.


TIFF 6.0 Image Support extensionTIFF 6.0 Image Support extension allows you to add version 6.0 TIFF files to views asimage themes and place them on layouts in pictures frames. TIFF 6.0 image supportincludes the use of GeoTIFF 1.0 tags to properly place the image in the propergeographic space, if present. ArcView GIS previously only supported version 5.0 TIFFimages.

VPF Viewer extension

VPF Viewer extension allows you to work with vector product format (VPF) data inArcView GIS. Using this extension, you can integrate VPF databases into your workseamlessly without having to convert these files into ArcView GIS shapefile format.

The VPF Direct Read function has been given the ability to add valid 3D VPF themes as3D type files. A Valid 3D VPF theme is one where there are no null Z values present inthe coordinate geometry. If any null values are found in the geometry, the theme will beadded to the view as a 2D type file. The VPF Direct Reader will automatically detectwhether a VPF theme is 3D and add it accordingly. To view the shapefiles in full 3D, youmust have the 3D Analyst extension loaded.


Optional extensionsThe optional extensions bring advanced, specialized GIS analysis to the desktop. Theyare available as separate software.

ArcView 3D Analyst extensionArcView 3D Analyst extension provides a suite of high-quality, easy-to-use tools forcreating, analyzing, and displaying surface data. This extensions unique capabilitiesinclude support for the TIN data model, 3D shapes, and interactive perspective viewing.


ArcPress for ArcView extensionArcPress is a graphics metafile rasterizer that enhances the printing and exportingcapabilities of ArcView GIS. ArcPress takes an ArcView GIS layout, rasterizes the data,and lets you set a variety of output, page, and print options.

ArcView Business Analyst extensionArcView Business Analyst extension is a unique set of GIS tools and data designedspecifically for business applications. ArcView Business Analyst lets users easily createand analyze market areas, perform site prospecting, profile customers and prospect forsimilar ones, conduct drive-time analysis, and create detailed reports.

ArcView Network Analyst extensionArcView Network Analyst extension (Version 1.0b) enables you to use geographicnetworks (such as streets, highways, rivers, pipelines, or electric lines) to solve problemssuch as finding the best travel route, generating travel directions, finding the closestemergency vehicle or facility, or defining service areas based on travel time. Networkdata used with this extension can come from any of the following sources: ArcView lineshapefiles, ARC/INFO network or regular line coverages, and CAD drawings.


ArcView Spatial Analyst extensionArcView Spatial Analyst extension (Version 1.1) provides tools to create, view, query,and analyze map cell-based raster data and to perform integrated vector-raster analysisusing feature-based and grid-based themes.

Capabilities include conversion of feature themes to grid themes, creation of bufferdistance and proximity surfaces from feature or grid themes, contouring and densitymapping from themes containing point features, slope and aspect mapping, cell-basedmap analysis, Boolean query on multiple grid themes, neighborhood and zone analysis,and grid classification and display. The extension includes an extensive Avenueprogramming interface for developing spatial analysis applications.

ArcView StreetMap extensionArcView StreetMap extension (Version 1.0a) adds nationwide address geocoding andstreet map display to ArcView GIS and includes a compressed street and landmarkdatabase for the entire United States on a single CD. The StreetMap extension uses aDynamap/1000 Version 2.0 data set from Geographic Data Technology (GDT),November 1994 current.

The ArcView StreetMap extension is not available on UNIX.


ArcView StreetMap 2000 extensionArcView StreetMap 2000 extension is enhanced StreetMap software developed jointly byESRI and GDT. StreetMap 2000 supports nationwide address geocoding and street mapdisplay. This extension uses GDTs Dynamap/2000 database, released in January of1997, and GDTs Matchmaker geocoding engine. GDTs Matchmaker geocoder offerstraditional geocoding capabilities and allows the matching of intersections and addressescomposed of alphanumeric notations. An Interactive Matcher dialog box displaysaddresses that failed to match, explains the problem, and suggests possible alternatives.Additionally, state boundaries, cities, airports, hospitals, parks, lakes, and river data canbe found on the CD.

The ArcView StreetMap 2000 extension is not available on UNIX.


ArcView Tracking Analyst extensionArcView Tracking Analyst extension can be used by anyone needing to view andanalyze the movement and status of objects through time. Developed in closecollaboration with TASC Inc., a major provider of advanced information technologysolutions for governments and businesses worldwide, the Tracking Analyst supports real-time Global Positioning System (GPS) and network connections, allowing you to mapevents in real time. For example, you could follow your delivery vehicles on their dailyroutes, track weather conditions such as hurricanes or lightning, or study the migrationroutes of animals.

The ArcView Tracking Analyst extension requires ArcView GIS Version 3.1 and isavailable on Windows 95, Windows NT 4.0, and Solaris.


Views and themesView properties

Background color

A new button on the View Properties dialog allows you to change the views backgroundcolor. From the View menu, choose Properties, and then click Select Color

. The new background color will also be maintained when displayed ina layout.

Setting projection for already-projected dataWhen you are adding projected data as a theme, ArcView GIS will detect whether itmight be projected and prompt you to set your views projection. You are not prompted ifthe extent of themes is beyond the standard geographic coordinates.

TOC StyleA new menu choice, TOC Style, has been added to the Views View menu. TOC Style letsyou change the following display settings of the Table of Contents (TOC): line flatness(degree to which the line symbols in the legend are flat), symbol length (the length of theline symbol in the TOC), and TOC text symbol (how text in a legend appears).


Label and text tools

Default settings for text and label tools dialog

Version 3.1 of ArcView GIS upgrades the Label tool and the Text tool as tool menus withadditional options for placing labels and text in a view or layout. These menus are nowexpanded to support the following new capabilities: labeling with a leader line pointing toa feature, labeling using banners, labeling using callouts, labeling with a background anddrop shadow, and labeling highways with standard highway shield symbols.

Default settings can be changed using the new Default settings for text and label toolsdialog, accessible from the Graphics menu. When you click on one of the icons, optionsassociated with the tool appear in the menu.

A sample extension for autolabeling more than one theme is also available in this release.

Spline text tool

A new Spline text tool with the ability to align text or position it along curved lineshas been added in this release. The tool is presented as an option on the Text tool menu.After indicating where you want text drawn (by clicking in your view or layout), use theSpline Text Properties dialog to enter, align, and draw your text.


Convert shapefiles to projected unitsFor projected views, Convert to Shapefile will now ask you if you want the new shapefileto be created in projected units. Previously, Convert to Shapefile only output the newshapefile in decimal degrees for projected views. (For nonprojected views, the newshapefile was and still will be created in the units of the base data.)

Adding themes

Adding already-projected data to a projected viewAdd Theme will now warn you if you try to add already-projected data to a projectedview (unless you are adding images). The data will be added to the view anyway, but itmay not display properly, as you cant view already-projected data in a projected view.

ESC cancels directory scan for Add Theme

ESC cancels directory scan for Add Theme. This allows you to immediately stopArcView GIS from reading all the directories. For example, if you have a folder withforty folders in it, and you want to go to the third in the list, wait for ArcView GIS todisplay the first three folders, then press ESC. Now double-click on the third folder in thelist.

Map and distance units automatically set

When adding a theme, if ArcView GIS detects that your data is in decimal degrees, it willautomatically set the map and distance units for you.

New View menu options

Manage Data Sources under View menu

A new menu choice, Manage Data Sources, has been added to the Views File menu.Manage Data Sources lets you copy, rename, and delete shapefiles.

Save Project As and Extensions under File menuSave Project As and Extensions have been added to the Views File menu to make theseoptions more accessible. (They have also been added to the interfaces of the otherdocument types as well, such as the Layouts File menu, the Projects File menu, and theTables File menu.)


Create Buffers wizardAccessed from the Views Theme menu, this wizard provides an easy-to-use set of panelsfor creating buffers. Using the panels, you will be able to select what and how to buffer,set buffer options, and specify where output should be saved.

Views can be exported into JPEG format Views can now be exported into JPEG format.

ESC stops drawing of themesPressing ESC will immediately stop the drawing of themes without clearing the viewsdisplay. (To support this functionality, the ESC accelerator to turn off all themes has beenremoved.)


Creating and editing spatialdata

Shape Properties dialogThis dialog was added to ArcView GIS to support the interactive addition, deletion, andediting of shape vertices. The main dialog identifies the type of shape, number ofvertices, and presents a list of vertices within a shape. You can choose to add a vertex to ashape or select multiple vertices and delete them. The dialog is available from a right-click popup menu when a shape is selected and editable.

Snap tolerance cursorWhen either general or interactive snapping is turned on, you now have the option ofdisplaying a circle representing the snap tolerance with the cursor as you create polylines,polygons, or edit vertices. This is known as the snap tolerance cursor. If general snappingis turned on, the circle represents the general snap tolerance. If interactive snapping isalso turned on, the circle will change to the interactive snap tolerance when you choosean interactive snap rule. By default, the snap tolerance cursor is turned on when snappingis turned on. You can turn the snap tolerance cursor off in the Editing panel of the ThemeProperties dialog or by using the Show/Hide Snap Tolerance Cursor toggle on the Viewspopup menu.

For more information about the snapping environment in ArcView GIS, refer to thesnapping topic in the ArcView GIS online help index.


Introducing measured and 3D shapesArcView GIS Version 3.1 provides support for measured and 3D data by extendingexisting ArcView GIS shape classes and providing an Avenue API for accessing themeasure and elevation values.

This means that data created by users of the ArcView 3D Analyst extension can bedisplayed and queried in 2D by all users of ArcView GIS Version 3.1.

What are measured and 3D shapes?

ArcView GIS has always stored geometric shapes using x,y coordinates. Points arerecorded as a single x,y coordinate pair, lines as a series of ordered x,y coordinates, andareas (polygons) as a series of x,y coordinates defining a set of line segments that havethe same start and end points.

ArcView GIS has extended the way it stores shapes. Instead of simply storing x,ycoordinates that define a shape, a shape can additionally store a measure value m and/oran elevation value z at each x,y. Therefore, one or more (x,y,m), (x,y,z), or (x,y,z,m)coordinates can represent each geometric feature.

Improved support for dynamic segmentationAll dynamic segmentation functionality available for coverage route systems in previousversions of ArcView GIS is now available on measured PolyLine shapefiles (that is, aPolyLineM or a PolyLineZ with the optional measure values attached).

The extended dynamic segmentation functionality includes the following:

The DynName class now accepts a measured PolyLine shapefile FTab on theMake request.

The Add Event Theme dialog now recognizes measured PolyLine shapefilesthat is, event themes can be defined on measured shapes.

The FTab requests ReturnLocation and ReturnRouteMeasure now work onmeasured PolyLine shapefiles.

The Export request on the FTab class can now convert an ARC/INFO coverageroute system into a measured (PolyLineM) shapefile.


TablesWhat's new for SQL ConnectWith PC versions of ArcView GIS, error messages returned from an Object DatabaseConnectivity (ODBC) driver are now appended to a file called ODBC.errlog located inthe ArcView GIS home directory. Error messages associated with incorrect logininformation, select statement syntax errors, or attempting to perform an invalid databaseoperation are normally returned from a driver. If the ODBC.errlog file does not exist, youwill get a message stating that the file has been created the first time a driver returns anerror message. Below is an example of an error message that may appear in this file.

Printing and layoutsNeatline buttonA neatline is a line that defines the maps frame and a border is composed of anadditional line or lines which are parallel to it. They are often used to provide the outerlimit of the map or just to provide a decorative element.

This release adds a new Neatline button to its layout interface that provides severaloptions for adding a neatline to your map. You can control the placement of a neatline byspecifying whether it should be drawn around all graphics, selected graphics, or insetfrom the margins of a page. You can also vary the appearance of a neatline by changingits line style, width, and corner shape. Additionally, you can add background color anddrop shadows.

To create neatlines and borders on your layout, use the Neatline button available inthe button bar. Once selected, the neatline dialog will appear.

Layouts can be exported into JPEG formatLayouts can now be exported into JPEG format.


DataArcView GIS Version 3.1 expands on the Canada, Mexico, U.S., and World data includedin the last release by adding new European data sets. In addition, all data sets will beaccompanied with legend files (.avl). ArcView GIS Version 3.1 will automatically openthe legend files when the data set is added to a view, providing symbols andclassifications for the theme.

United States

Updated demographic attributes supplied for states, counties, cities, and census tracts andblock groups are now joined to the shapefiles attribute tables. New detailed data sourcesinclude rails and highways from the National Transportation Atlas, several shapefilesfrom the Geographic Names Information System, and landmark data from GDTDynamap/2000. New data for states include census tracts, census block groups, ZIP Codegeography, rivers, and major roads.

Europe

Includes European Nomenclature of Territorial Units for Statistics (NUTS) statisticalcollections (03), cities, highways, lakes, and rivers. NUTS include the U.S. analogy ofcountry, region, state, and county boundaries and attributes similar to U.S. censusstatistics.

European Countries

Includes national boundaries, provinces, counties, regions, states, districts (whichever isapplicable), cities, highways, lakes, and rivers for the following countries:

Albania, Austria, Belgium, Bosnia, Bulgaria, Croatia, Czech Republic, Denmark,Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia,Lithuania, Luxembourg, Macedonia, Netherlands, Norway, Poland, Portugal, Romania,Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey, United Kingdom, and Ukraine.

World

Includes 1998 countries of the world with demographic attributes.


SamplesThe samples directory contains a rich resource of sample programs you can use directlyin your work or study to learn more about how ArcView GIS works. There are threekinds of samples in the samples library: Avenue scripts, extensions, and other sampleprograms. For a listing and a description of samples in this directory, refer to Samplescripts and extensions under the Contents tab in the Help Topics.

There are several new sample extensions included in ArcView GIS Version 3.1. Theextensions are located in the $AVHOME\samples\ext directory in your ArcView GISinstallation.

ArcView Connect for R/3 extensionThe ArcView Connect for R/3 sample extension allows you to initiate SAP R/3function modules from ArcView GIS. Using this extension, you can download R/3 datainto ArcView GIS for visualization and spatial analysis, as well as interact with SAP R/3on a transactional basis. This extension allows you to immediately utilize R/3 standardfunctions and provides a flexible tool to build custom applications that require ArcViewGIS and SAP R/3 connectivity.

ArcView Connect for R/3 will quickly allow, for example, a download of customerinformation from R/3. If the customer data has address information, it can be geocoded,displayed, and analyzed with any other spatial data using ArcView GIS. ArcViewConnect for R/3 can also be used to access data stored in several other SAP modules suchas Materials Management (MM), Plant Maintenance (PM), Sales and Distribution (SD),Asset Management (AM), Service Management (SM), and others.

This extension uses a generic DLL that was built using the SAP C++ Developer Kit. TheDLL is wrapped in a Visual Basic GUI interface and allows communication to SAP R/3via the SAP RFC (Remote Function Call) libraries. All source code for the VB exampleinterface application is provided as part of the extension.

The extension requires a standard installation of the Samples. Its file is called esrir3.avxin the $AVHOME\samples\ext\esrir3 folder.


Map Labeling extensionThis sample extension adds a choice to the Theme menu that gives you an interface forlabeling one or more themes so placement conflicts between labels will be resolved forall labels, regardless of what theme the label belongs to. The interface allows you to setpriorities and rules for each theme that goes into the labeling process. For example, youcan assign a different font to each theme.

The extension requires a standard installation of the Samples. Its file is calledmultmlab.avx in the $AVHOME\samples\ext folder.

MGE Reader extensionThis sample extension allows you to integrate data created in Intergraphs MGE softwareor Bentleys MicroStation GeoGraphics software. You can also use data in MicroStationdesign files linked directly to external tables and ArcView GIS will manage the linkagesfor you. ArcView GIS presents this data in a manner familiar to ArcView GIS users whilemaintaining many tools and features of the native software. You can symbolize, query,and analyze the data just like any other spatial data without first converting the data inshapefile format. This allows you to view the most up-to-date data within ArcView GISwhile the underlying data is constantly being updated in the native software.

This extension requires a standard installation of the Samples and is dependent on theCAD Reader extension. Its file is called MGEView.avx in the $AVHOME\samples\extfolder.
