2. Content
• What data is available in CAD format?
• Where do I get the data?
• How do I use the data?
• Copyright and Resources

3. What data is available in CAD format?
• Vector datasets:
– VectorMap Local [DWG]
– MasterMap Topography Layer [DWG]
• Height datasets:
– Terrain 50 DTM and contours [ASCII, Shape, GML]
– Land-Form PROFILE DTM and contours [DXF]
– Land-Form PANORAMA DTM and contours [DXF]
• Backdrop mapping [TIFF]
– Various products e.g. 1:50,000 raster, all in TIFF format
• Other
– Building Height Attribute: extension to MasterMap Topography
Layer [CSV]

4. Vector Map Local data
• Scale 1:10000
• Includes contours and
spot heights
• Formats – GML, DWG, SHP
• Supplied in 5x5km tiles

5. OS MasterMap
• Vector map product, most detailed
mapping available of GB.
• Integrated Transport Network layer
– GML format only.
• Topography Layer – GML, DWG and
File Geodatabase formats.
• Building Heights data added in
2014, CSV or KML format.
• Coming soon:
– Sites Layer
– Urban Paths (ITN layer)
MasterMap Topogaphy Layer (DWG format)

6. Height Data
• Various Raster (DTM)
and Vector (contour)
datasets available:
– Terrain 50 [ASCII, Shape,
GML] – replacement for
Land-Form PANORAMA
– Land-Form PROFILE [DXF]
– withdrawn by OS
– Land-Form PANORAMA
[DXF] – withdrawn by OS
• Coming soon:
– OS Terrain 5 –
replacement for Land-
Form PROFILE
Terrain 50 DTM
Terrain 50 Contours

7. Backdrop mapping
• 9 products available.
• Raster maps – useful as
backdrop.
• TIFF image format.
• Largest scale at top, 1:1000.
• MiniScale smallest scale –
1:1000000.
1:25,000 Colour Raster

8. Building Height Attribute data
• Released by OS in March 2014
• Enhancement to Topography
layer
• Covers around 10000 sq km of
major towns and cities in GB -

• Alpha release – no guarantee
error free
• In future will be included in
Topography layer
• CSV or KML format
• EDINA supplies as 5x5km grid
tiles

10. Where do I get the data?
• Data Download
– download OS
mapping data
for use in
GIS/CAD

11. Data Download
• All available OS
map data
• Download several
map products in
one order
• 5 categories of
map data
• 3 steps to order
map data

12. Using Data Download
3 step process:
1. Select area
2. Choose data
3. Add to basket
– Options to
change
format,
version and
layers

13. Basket options
• Select version, format and layers in the basket.
• Options vary between map data products.

14. How do I use the data?
• Add VectorMap Local to AutoCAD Map 3D
• Add OS MasterMap topography to AutoCAD Map 3D
• Combine OS MasterMap with Building Height
Attribute data in AutoCAD Map 3D and InfraWorks

15. Add VectorMap Local to AutoCAD Map 3D
• Download data in DWG format
• Open in AutoCAD Map 3D

16. Add OS MasterMap topography to AutoCAD
Map 3D
• DWG format:
– Will open directly in AutoCAD products
– Includes default OS representation
– Attributes stored as Extended Attribute Data (Xdata),
which is not easy to interrogate
• GML format:
– Can be imported in to AutoCAD
– Minimal representation
– Control over which features are imported
– More detailed attribute analysis possible
– Can control the order in which layers are drawn

17. Combine OS MasterMap with Building Height
Attribute (BHA)
• Download MasterMap Topography layer in GML
format and BHA data in CSV format
• Process BHA data, save as Excel spreadsheet and set
up an ODBC connection to the spreadsheet
• Join BHA data to the MasterMap data in AutoCAD
Map 3D
• Export joined data as .sdf file
• Open .sdf file in InfraWorks and extrude buildings
using BHA value

18. New datasets – coming soon
PointX [points of interest] OS MasterMap ITN - Urban Paths Theme
OS MasterMap Sites Layer
OS Terrain 5

19. Future developments
• MasterMap in outline/plan
format in DWG
• 3D buildings in DWG
format
