LiDAR processing with LAStools in the Canary islands

A small tutorial on the capabilities of LiDAR processing with LAStools at the example of a project in the Canary Islands, Spain, in Spring of 2012. We used LAStools to create canopy height maps, forest density grids, and showed that the LiDAR that was already owned by the municipal government of the Canary Islands could be used to significantly improve their photogrammetrically derived DTMs as we discover elevation differences of up to 25 meters where entire hills and valleys had been hiding under the canop
