  • Topography Layer is a detailed, intelligent, geographic database. It contains almost half a billion features from the built and natural landscape of Britain. Detailed and surveyed to a high degree of accuracy, the Topography Layer is continually revised to incorporate changes to the urban and rural environment. It consists of nine themes: land area classifications; buildings; roads, tracks and paths; rail; water; terrain and height; heritage and antiquities; structures; and administrative boundaries. The ITN Layer is a detailed, accurate and up-to-date digital dataset consisting of a Roads Network theme and a Road Routing Information (RRI) theme for Great Britain. The Roads Network contains road categories, from motorways and primary routes to named and unnamed minor roads and local streets. RRI contains features such as height, weight and width restrictions; traffic calming; turn restrictions; and one-way roads as well as vehicular access and time restrictions. Other OS Layers – not available within Digimap Address Layer The most complete national address dataset for the whole of Great Britain. Imagery Layer The OS MasterMap Imagery Layer is a maintained dataset of  high-quality aerial photography and provides a detailed aerial map of Great Britain.

    8. 8. Formats and conversion guidance http://digimap.edina.ac.uk/webhelp/os/data_information/data_formats/new_data_translators
    9. 9. Backdrop mapping •Largest scale at top •Raster data 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 •No conversion requirements
    10. 10. Backdrop mapping • Information boxes indicate: – Scale – Format availability – Version – Data Allowance – Terms of use • Version and format can be changed in order Basket, under options
    11. 11. Land and Height data •PROFILE 1:10000, created 2009. Contours at 5m intervals with spot heights. •PANORAMA 1:50000, created 1996. Contours at 10m intervals with spot heights. •DTM – Digital terrain model – 3D representation of terrain surface.
    12. 12. Land and Height data • Contours, Panorama available in DXF, NTF formats • DTMs available in DXF, NTF, ASC, TIFF • DXF AutoCAD format • Can also use TIFF and ASC formats in AutoCAD
    13. 13. Vector Data• Formats available for products not consistent, e.g.: – VectorMapLocal – GML, SHP – Strategi – SHP, DXF, TAB, NTF, MIFMID• SHP available for all vector maps, except Meridian 2 Tiles (NTF, DXF)
    14. 14. OS Vector Map Local data • Suitable for 1:3000 to 1:20000 viewing • Available in OS Collection Data Download – GML format: 1. Direct import of GZ file to AutoCAD via Insert > Map Import 2. Convert to SHP or TAB with Rolta Vector Map Loader
    15. 15. Rolta Vector Map Loader • Free download: http://www.rolta-europe.com/osvector.html • Converts OS VectorMap Local to SHP or TAB formats
    16. 16. Shape files • Shape files can be used in AutoCAD. • Remember to keep all constituent parts together - SHP, DBF, SHX:
    17. 17. Map Import • Map Import function allows you to import external file formats
    18. 18. Map Import • Many map data products from Digimap Collections are available in formats that can be imported to AutoCAD Map 3D, e.g. SHP, MIF/MID, TAB, GML
    19. 19. SDF • SDF is a native Autodesk file-based geospatial format that is optimized for storing large, classified data sets. • SDF is similar to SHP format in that it contains both spatial data and attribute data. However, unlike SHP, it stores both types of data in a single file rather than a set of files.
    20. 20. Connect to data • AutoCAD offers ability to connect to a feature source, such as databases, files (SHP, SDF), web servers (e.g. OpenStream)
    21. 21. Connect to data • Smaller DWG file – stores connection and style, not data • Easier to share data
    22. 22. Export options • Not tied to AutoCAD formats
    23. 23. Export options
    24. 24. OS MasterMap data • AutoCAD users generally interested in large scale (very detailed) data • Largest scale data in Digimap is OS MasterMap – available in Data Download – GML format – TIFF format • Digimap Help pages - detail how to use MasterMap data in AutoCAD
    25. 25. OS MasterMap layers
    26. 26. OS MasterMap data in AutoCAD – GML format Using OS MasterMap in AutoCAD: 1. Later versions of AutoCAD (post-2008) – built-in MasterMap Importer, accepts GZip file (in data download file from Digimap) 2. Earlier versions of AutoCAD (pre-2008) or other CAD packages without a MasterMap importer – Convert to DXF or DWG with InterpOse
    27. 27. MasterMap Download file • Data is delivered in GZip file - GML data within the GZip
    28. 28. MasterMap download file • Here we have extracted the GML file from the Gzip file…not always necessary to do this, e.g. AutoCAD 2010 and later can import the GZip file
    29. 29. 1. Direct import of GZip file to AutoCAD • First, load a template file from the Autodesk website • Import the GML data • Update the data to the style within the template files What is the template file? From the AutoDesk website: – ‘This is a drawing template file (dwt) that stores the classification definitions for OS Mastermap data. Using this template allows users to quickly visualise MasterMap data using suggested OS colour standards’. • Can also load the GML directly, without a template…then set own style
    30. 30. Step 1 - Download the DWT drawing template file http://www.autodesk.co.uk/adsk/servlet/item?siteID=452932&id=7986
