GroundMap (Ordnance Survey Meridian 2)
GroundMap is derived from the Ordnance Survey Meridian 2 dataset, covering GB (not including the Isle of Man). It consists of DTM (Digital Terrain Model) data with 200m grid intervals providing a cost-effective solution for small-scale terrain modelling and display.

- Background terrain mapping;
- Line-of-site analysis;
- Site planning.
