InterMap Technologies (USA) have produced an ‘off-the-shelf’ elevation model for the entire island of Ireland using an InSAR airborne radar mapping system. The terrain data can be supplied as a 5m grid DSM (all features) and/or 5m grid DTM (bare earth). Vertical accuracy of ±1m RMSE. From this 1m contour datasets can be derived. BKS (NI) have access to download this data directly which provides a fast, lower accuracy, cheaper solution to LiDAR. Can be used for preliminary wind farm design, environmental, and preliminary flood analysis.
Minimum order size is 2 square kilometers.
