  • Multiple data formats – raster and vector
  • Can do all files from 1 order (chunks) Cannot do files from multiple orders – well you can but you have to edit the name of the order (numbers)
  • This slide will describe the process of getting ITN data into ArcGIS. It should cover the use of Productivity Suite to convert the data, the use of the Prepare ITN data for Network Analyst tool and then viewing it in ArcGISPoints to highlight:Do not use remove duplicates on importPick as small an area as possibleYou will always get national coverage of RRIAlways use a file geodatabaseIt may take a very long time (up to an hour for a small area, 24 hours for a large area)It may run out of memory if you try and do something the size of England
  • The raw data loaded – note the RRI covers the UK but the actual road network is just a small area
  • The raw road network data –links and nodes with RRI
  • A lot of options to choose from
  • Use the Network Analyst toolbar to calculate routes
  • This slide will show the process needed to allow you to display MasterMap data that has been converted and is in OSGB 36 over the top of the built-in Esri Basemaps including the Bing aerial imagery.For most applications choosing the “Petroleum” shift should be sufficient accuracy. If higher accuracy is required then the OSTN02 transformation should be used.
  • Mismatch when MasterMap (OSGB 36) used with Bing Basemap
  • Need to set up transformation from WGS84 to OSGB 36 Use Petroleum or the OSTN02 for better accuracy
  • Now they line up
  • This slide will show how to use OpenStream data in ArcGIS desktop using the Add WMS layer
  • 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 need to change the Data Frame Coordinate system to OSGB 36
  • The products displayed will change as you zoom in and outProducts include:MiniScale1:250,000 Colour RasterVectorMap DistrictOS StreetView
  • Use ArcGIS.com to display OpenStream data as a basemap
  • Use the “Add Layer from Web” to add an OGC WMS Server. Enter you URL including the API key
  • Just remember to include the copyright statement"Contains Ordnance Survey data. © Crown copyright and database right 20YY." and "Data provided by Digimap OpenStream, an EDINA, University of Edinburgh Service" And don’t share your API key

  • 8. Esri UK and Eduserv Seminar 2011
    MasterMap Downloader
    Select either Topography or ITN layers
    Select all themes or specify which ones you want
    Road Network and/or Routing Info
  • 9. Esri UK and Eduserv Seminar 2011
    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
  • 10. Esri UK and Eduserv Seminar 2011
    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)
  • 11. Esri UK and Eduserv Seminar 2011
    Launch Productivity Suite v2.1
    Launch
    Productivity Suite v2.1
    Loads of tools –
    We want OS MasterMap Data Converter
  • 12. Esri UK and Eduserv Seminar 2011
    OS MasterMap Data Converter
  • 13. Esri UK and Eduserv Seminar 2011
    Select files/folder
    Process all the files from one order, great for batching.
  • 14. Esri UK and Eduserv Seminar 2011
    Choose your Geodatabase
    Select a storage type:
    ArcSDE – for multi-user access
    Personal GDB – based on Access and has a 2Gb size limit
    File 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)
  • 15. Esri UK and Eduserv Seminar 2011
    Create or add to GDB
    New
    Existing
    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.......
  • 16. Esri UK and Eduserv Seminar 2011
    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.
  • 17. Esri UK and Eduserv Seminar 2011
    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.
  • 18. Esri UK and Eduserv Seminar 2011
    Converting Options
    Change-only Updates
    Versioning control
    Remove Duplicates – handy if you have a large area with “chunking” this will merge features that appear in multiple chunks
  • 19. Esri UK and Eduserv Seminar 2011
    Logs and Working Dir’s
    Log Files
    Handy to know where the log files are if things go wrong
  • 20. Esri UK and Eduserv Seminar 2011
    Save a Profile
    Save Profile
    Save the profile if you know that you will be repeating the process and want to add more data into the same GDB
  • 21. Esri UK and Eduserv Seminar 2011
    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.
  • 22. Similar for ITN Conversion
    Select the ITN Road Layer
  • 23. ITN Conversion
    RRI will cover Great Britain

  • 25. ITN Data Preparation Options
    Build Network Dataset
  • 26. ITN Network Dataset

  • 27. Now to View the data in ArcGIS
  • 28. Esri UK and Eduserv Seminar 2011
    Connect to GDB
    Launch ArcGIS10
    Click 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”
  • 29. Esri UK and Eduserv Seminar 2011
    Ehhh, that doesn’t look right
    Data needs styled to make it easier to understand

  • 30. Esri UK and Eduserv Seminar 2011
    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 FilesArcGIS
    This should have the following files:
  • 31. Esri UK and Eduserv Seminar 2011
    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
  • 32. Esri UK and Eduserv Seminar 2011
    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
  • 33. Esri UK and Eduserv Seminar 2011
    Done.
    Well pretty close...

  • 34. We’ll now to look at something you might do with the data in ArcGIS 10
  • 35. What do we want to do?
    Display MasterMap data on top of built-in Basemap - Start with the MasterMap data…
    © Crown Copyright/database right 2010. An Ordnance Survey/EDINA supplied service
  • 36. But the data doesn’t match…
    And add in the Bing Aerial Imagery Basemap...
    © Crown Copyright/database right 2010. An Ordnance Survey/EDINA supplied service
  • 37. Choose a transformation…
    From WGS84  OSGB 36
    Use Petroleum or OSTN02 transformations for better accuracy
  • 38. Now it all fits…
