Digimap Roam

Easy to use online mapping tool:

Search Customise Annotate

Customise the content


Customise the data by turning layers on/off

Quick and Easy Print


Print map as PDF at A3/A4 Landscape/Portrait


Data Products Available

OS Products – note the rasterised MasterMap available at 2 scales

OS Open Products – available in bite sized chunks making them easier to work with


MasterMap Downloader

Select either Topography or ITN layers

Select all themes or specify which ones you want

Road Network

and/or Routing Info


Download123456.zip

Extract the zip to a new folder

You should have a collection of files.

Conditions.txt – all the license information and copyright stuff

Contents – useful info about what you selected

TOID files –

###-MM-topo.gml – the data in standard OS GML format


Productivity Suite v2.1

Developed by esri UK and available as part of the Esri UK Chest/Eduserv agreement.

- Loading and updating OS data, including:

- MasterMap

- NTF data

- Can handle Change Only Updates for MasterMap

- Building routable networks using Ordnance Survey Integrated Transport Network (ITN)


Launch Productivity Suite v2.1

Loads of tools – We want OS MasterMap Data Converter


OS MasterMap Data Converter


Select files/folder

Process all the files from one order, great for batching.


Choose your Geodatabase

Select a storage type:ArcSDE – for multi-user accessPersonal GDB – based on Access and

has a 2Gb size limitFile GDB – similar to Personal GDB

but unlimited size and uses binary file system (note – tables limited to 1Tb by default, but able to store 256 Tb)


Create or add to GDB

Connect to an existing GDB or create a new one.Adding to existing GDB is good as you can add new data to one centralised GDB and for a few other reasons as we will see shortly.......

NewExisting


Choose a prefix

Data Prefix – Specify a prefix for the data. This is useful if you plan to keep more than one MasterMap Download in the same GDB, the resulting files will have the prefix making tem easier to find.


Select the feature types

Specify what to convert:This section allows you greater control over exactly what is going to be converted. I tend to convert all topography options.


Converting Options

Change-only Updates

Versioning controlRemove Duplicates – handy if you have a large area with “chunking” this will merge features that appear in multiple chunks


Logs and Working Dir’s

Log FilesHandy to know where the log files are if things go wrong


Save a Profile

Save ProfileSave the profile if you know that you will be repeating the process and want to add more data into the same GDB


Convert

And they’re off!This may take some time.... Time for a brew.Error and warnings will be highlighted, check the log files for more details.

Similar for ITN Conversion

Select the ITN Road Layer

ITN Conversion

• Now to View the data in ArcGIS


Connect to GDB

Launch ArcGIS10Click the “add data” button and navigate to the GDB you created in Productivity Suite, you will see the data with the pre-fix.Select the features and “add”


Ehhh, that doesn’t look right

Data needs styled to make it easier to understand



Get Symbology

Symbology files are supplied with Productivity Suite and are available on the esri uk website (Myesriuk)

Extract the symbology.zip and put the contents somewhere sensible that you will remember: C:\Program Files\ArcGIS

This should have the following files:


Load Symbology Files

Many methods of associating the data with the symbology, this is the one I tend to use:

• Add lyr file navigate to the layer files (c:prog files/ArcGIS/symbology or a copy of them next to the geodb)

• Add the layers you want for Area, Line,Point, Bdy...)• Back in ArcGIS – double click the layer• Select source tab and set data source • Repeat


Symbology Tips

• Set the annotation line style to “no color” • Set the label (label tab) to active and the label field to “Text”• Associate the boundary class theme to one of the options

(note – you may not have a boundary feature in your downloaded data so may not see anything change)

• Remember to add the style file in the symbology folder to your ArcGIS installation folder C:/program files/arcgis/desktop10/styles


Done.

Well pretty close...


We’ll now to look at something you might do with the data in ArcGIS 10

What do we want to do?

Display MasterMap data on top of built-in Basemap - Start with the MasterMap data…


But the data doesn’t match…

And add in the Bing Aerial Imagery Basemap...


Choose a transformation…

From WGS84 OSGB 36

Use Petroleum or OSTN02 transformations for better accuracy

Now it all fits…


An alternative to downloading and converting data

Digimap Training Workshops

Digimap OpenStream in ArcGIS

An OGC WMS that’s free to use for academia

Delivers OS OpenData

Uses an API key you get by registering

OpenStream in ArcGIS

In ArcGIS, use the Add WMS Server interface to add the OpenStream URL, including your own API key


Initially it will appear in WGS 84


You should change the Data Frame Coordinate system to OSGB 36

Digimap OpenStrean in ArcGIS

The products displayed will change as you zoom in and out

Products include:• MiniScale• 1:250,000 Colour Raster• VectorMap District• OS StreetView

You can also view it in ArcGIS.com

OpenStream in ArcGIS.com

Add OpenStream in ArcGIS.com as a basemap


Use the “Add Layer from Web” to add an OGC Web Map Server. Enter you URL including the API key


You can add annotations and print
