I have a general question about how can I get the elevation (z) data from a pointcloud (las) along a trajectory. I have a shape file with x, y coordinates and I have the related .las files. And I am using lastools for the point cloud.
You did not say whether you have access to ArcMap or not and I am not familiar with lastools. IS this a tool kit in ArcMap? Anyway, I apologize in advance if the answer is not of any help. If you have access to ArcMap you can use this tool: and then use the raster calculator to extract the value that you need.
