A Solid Terrain Model(TM) produced for Snowdonia National Park has been completed. The project was undertaken by Touch the Earth Ltd..

Solid Terrain Model(TM) of Snowdonia National Park

We produced the digital terrain model from an original airborne LiDAR dataset of 28 million points and aerial photography at 25cm in ECW format. The dataset needed to be rotated by an arbitrary amount to ensure the panel was exactly rectangular and that the terrain data and texture matched after rotation.
