UK NTF

UK NTF (National Transfer Format) is a vector interchange format used to distribute digital map products from the Ordnance Survey.

Products

A list of digital map products should be available from the Ordnance Survey web site, somewhere. I used to redistribute the .pdf files for their various data product guides from here (since they are often hard to find on their web site), but their "Intellectual Property and Legal" staff asked me not to, so you will have to dig around on their site to find them if they are still available.

Products I have successfully read:

  1. Land-line
  2. Strategi
  3. Meridian
  4. BaseData.GB
  5. Boundary-Line
  6. Land-Form Panorama
  7. OSCAR
  8. Address Point
  9. Code Point

Code

I have not packaged standalone NTF reading source code at this time. The source code is part of my OGR library, and can be found in the gdal/ogr/ogrsf_frmts/ntf subdirectory.

Digital National Framework

The Ordnance Survey is working on an overhaul of their digital mapping management and distribution, and apparently will be distributing data in DNF (a particular set of OGC GML 2.0 schemas) at some point in the future.
