GIS and mapsWhat do you use maps for?What do you use GIS maps for?

Maps and layersA GIS uses layers to characterize and describe our

world

Spatial Information:Where is it?

51°N, 112°W

We can describe anyelement of our worldin two ways:

ArcMap: Mapping application

Feature classes and layers Each layer references a feature class (data) Layers define the

appearance of the data

Feature class organization Each feature class contains a set of

features and attributes Each feature has one record

How is geographic data stored?Geodatabase

Geodatabase withfeature classes, a

raster dataset, and astand-alone table

Consider…

Do you want to see all the layers in your mapall the time?

Do you want to see all the features in a layerall the time?

What are some ways to control the display oflayers and features in ArcMap?

Zooming using commands and tools Zoom toLayersSelectionsBookmarksFull extent

Zoom to selectedfeatures

Onlylakeslargerthan 500squarekilometersaredisplayed

All lakes are displayed

Controlling which features displayDefinition queryQuery statement defines which

features draw

Query statement:Attribute field: "SQKM"Operator: >Value: 500

"SQKM" >500

Controlling when layers display Scale rangeLayer turns on or off when scale threshold

is crossedRailroads don’t display

when zoomed outRailroads display

when zoomed in to a specifiedscale

1:5,000,000 1:3,000,000

Grouping layers Thematically related layers grouped in the

table of contents

When Transportation isunchecked,

member layers do not draw

Where does map text come from?

What are labels? Software-generated map text based on

attribute values

Dynamic label placement

Mississauga and St.Catharines suppressed to

avoid conflict

Preferred label position is top right

Positionsvary, but all labels fit

Label symbology Font, size, color, more

Arial, 14-point, Bold, Purple Heart

Character spacing 25.00

SQL queryDraw labels only for specified attribute values Example: Label only international airports

Scale rangeDraw labels at specified scales Example: Label airports only at large

scales

Scale >1:2,000,000

Scale <1:2,000,000

Label classesAdditional sets of labels for a layer Typically use different symbology

Two label classes based onpopulation

Label expressionsUse scripting functions

to format labels
