Features and benefits

Available in 10m grid intervals.


Can be used in the electronic process of representing topography in 3 dimensions, including slope and aspect maps.


Using Geographical Information System (GIS) sofware, orthophotographs and maps can be draped over a Triangular Irregular Network (TIN) derived from a DTM to create a 3D view of the land surface.


DTM data can also be used in a GIS to create thematic maps, grids and contours.

 

Technical Information

  • The DTM is derived from OSNI’s Orthophotography dataset.
  • All height measurements refer to elevation in metres above mean sea level at Belfast Lough.
  • DTMs can be used to generate 3D TINs.
  • 95% of the data is within +/-1.0m accuracy.
