  • It’s straightforward to use Data Download – ordering map data involves 3 steps:Select your area on the map – there are 4 methods for selection. The shaded orange area you see here is our selected area.Select the map data that you wish to download. You can open any category of map data by clicking on the name. Then it’s a matter of ticking the box next to any map data you wish to download. You can download as many as you like in an order, provided you do not exceed the allowances. There is an allowance for each map data product – in order that our servers can process orders as quickly as possible.Third step is to add to basket. Once you click the add to basket button, your basket pops up on screen. You can then select from different formats, date versions and map layers, where available. Options will different depending on map product.
  • Transcript

    • 1. Digimap data in GIS 23 October 2013 James Crone, Edina Geo User Support Vivienne Carr, Edina User Support
    • 2. Content • Roam • Data Download • Issues for users: • • • • Unzipping Formats Tile sizes Styling vector data • Demo: • View vector and raster data to ArcMap • Digimap OpenStream • Copyright and Resources
    • 3. Digimap OS Collection • Roam – view, annotate, print OS maps at a range of fixed scales • Data Download – download OS mapping data for use in GIS/CAD
    • 4. Roam Save & open maps, Print, Map Content, Map Info. Search, scale bar, overlays, annotate, measure, change basemap
    • 5. Annotation tools • Toolbar appears at the top of the screen – can be moved around • Main options to add annotations in the Draw & Create area – add symbols, text, lines, polygons, pre-defined shapes • Options: • • • • Make visible on PDF map print Save map and annotations within Digimap (can display annotations in any Digimap Roam service e.g. Ancient Roam) Export annotations – available formats: Shapefile, KML, GeoJSON Import annotations – following formats: Shapefile, KML, GPX, CVS, GeoJSON
    • 6. Data Download • All available OS map data in Data Download • Download several map products in one order • 5 categories of map data • 3 steps to order map data • Maps provided for context only
    • 7. Data Download Click + or on category name to open and see available map data products: • OS MasterMap – most detailed topographic mapping of GB, transport network map data • Background Mapping – raster maps at range of scales, all in TIFF format • Land and Height data – contours and Digital Terrain Models • Vector data – range of scales and formats • Boundary and Location data – administrative boundaries, postcode data, gazetteers
    • 8. Using Data Download 3 step process: 1. Select area 2. Choose maps 3. Add to basket – Options to change format, date and layers
    • 9. Basket options • Click Change to select format, layers and map date • Options vary between map data products
    • 10. Available datasets and dates http://digimap.edina.ac.uk/webh elp/os/data_information/os_data _issues/os_update_dates.htm#
    • 11. Issues for Digimap users • Formats - some vector map data formats available from Digimap may not be compatible with your GIS/CAD software • Unzipping – all data is provided in a zip archive file. Sometimes data is zipped within the zip archive! • Tile sizes - map data products are provided in different tile sizes • Styling of data – vector map data downloaded from Digimap will not have a cartographic style, when viewed in GIS/CAD
    • 12. Poll What software do you use most often with geospatial data? A. ArcGIS B. CAD C. QGIS or other open source software D. I don’t use any software E. Other
    • 13. Unzip standard Digimap zip files • You will download 1 zip archive file for each order you place in Data Download • Use the standard Windows unzip facility to unzip and extract the file contents to a location on your computer
    • 14. Unzip standard Digimap zip files Zip archive file contents: • Sub-folder for each map product in your order • Citations and contents text documents at top level
    • 15. Sub-folder contents • Within each sub-folder, data files and conditions of use text file. • Data from Digimap OS is covered by the Digimap licence OR the OS OpenData licence. So each data folder has a conditions document that specifies which conditions apply. • NOTE: for some products, the map data will be zipped in the sub-folder. Image of Vector Map District data. Check before you try to add it to your software!
    • 16. OS MasterMap zip files • OS MasterMap vector data is delivered in GZip file - GML data within the GZip • Can extract the GML file from the GZip file…but generally not necessary to do this. • Note: standard windows unzip will not extract the Gzip. Use WinZip, 7Zip, Gzip.
    • 17. Formats and conversion guidance http://digimap.edina.ac.uk/webhelp/os/data_information/data_formats/new_data_translators.htm
    • 18. Data formats Format Compatibility DXF, DWG Drawing Exchange, or Drawing, format, AutoCAD MIF/MID MapInfo format NTF National Transfer format, non-proprietary. Older format, developed in 1990s. GML Geography Markup Language, non-proprietary SHP Shape file, ArcGIS format TIFF TIFF image format, used for background mapping products.
    • 19. TIFF files •Raster data (backdrop mapping) all supplied in TIFF image format, with a TFW file •TIFF World Files contains location, scale and rotation of TIFF map. Keep in same folder as TIFF files!
    • 20. Shape files • • • ArcGIS format, can be used in other software too. Remember to keep all constituent parts together SHP, DBF, SHX, P RJ. Image of folder containing VectorMap Local shape files
    • 21. Using OS MasterMap • OS MasterMap supplied in GML format (within a GZip file) • Possible to import directly to many software packages, may get better results if convert to a compatible format. • Conversion options?
    • 22. Conversion tools ESRI Productivity Suite • Converts OS MasterMap data in GML format to ESRI Personal Geodatabase format • Converts NTF data to ESRI Personal Geodatabase format • Free if your institution has a licence for ArcGIS – ask your Eduserv CHEST rep. • Evaluation version: http://www.esriuk.com/software/arcgis/pr oductivitysuite/download
    • 23. Conversion tools • Free download, which converts MasterMap GML data to ArcGIS, CAD and MapInfo formats • http://misoportal.com/data/interpose-for-digimap/
    • 24. InterpOSe output formats
    • 25. Tile sizes • Map data from Digimap is typically provided in tiles that have been referenced to the British National Grid - exceptions are OS MasterMap vector data, gazetteers, products provided with national coverage such as Boundary-Line. • Data from Digimap is in a range of sizes, from 1 x 1 km tiles to 100 x 100 km tiles. • Typically the more detailed the map data, the smaller the tile size, e.g.: Product Tile size 1:50000 raster 20 x 20 km 1:250000 raster 10 x 10km Vector Map Local 5 x 5km 1:10000 Vector Map District 1:50000 100 x 100 km
    • 26. Merging tiles • Where tiles are provided in smaller sizes, e.g. 5 x 5 km, possible to merge them into one Image: OS Terrain contours in ArcMap, for area of South East England
    • 27. Clipping tiles • Where tiles are provided in large sizes e.g. 100 x 100 km, possible to clip them to smaller area Image: Vector Map District clipped to smaller area in ArcMap
    • 28. Styling vector data • Vector data (e.g. OS MasterMap, OS VectorMap Local) will not have the same appearance as it does in Digimap, when viewed in ArcGIS
    • 29. Styling options In ArcGIS – do this in Symbology tab of map layer properties: 1.Generate your own style using layer attributes 2. Apply a layer file that contains styling information – find available files in OS and Marine Help pages. Geology Digimap, layer files provided in download file. 3. Match to symbols in a pre-installed style, e.g. from InterpOSe
    • 30. OS MasterMap symbology • Productivity Suite: – symbology files available with the evaluation software: http://www.esriuk.com/software/arcgis/productivitysuite/download# • InterpOse – provide a style file for ArcGIS with the InterpOSe installer • AutoCAD – template file available from AutoCAD website. Load the template file, then the OS MasterMap data: http://www.autodesk.co.uk/adsk/servlet/item?siteID=452932&id=7986865 • Digimap guides on all of the above processes here: http://digimap.edina.ac.uk/webhelp/training/training.htm
