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: enter image description here and then use the raster calculator to extract the value that you need.

  • Thanks! I dind'nt know this tool in ArcMap, it can be very useful, but I have more than hundreds of files, so I need to automatize athe process. Lastools is a bunch of programs especially for processing lidar datas. – krszt May 10 '19 at 6:57
  • In that case you may want to create a single LAS aggregating them all together. Take a look at this link and then use the LAS Dataset to Raster tool to extract the z value for elevation. – Milad May 10 '19 at 23:04
  • Thank you! Could you please send the link agait...somehow it doesn't work... – krszt May 15 '19 at 7:08
  • I am sorry for the non functioning link: desktop.arcgis.com/en/arcmap/10.3/manage-data/las-dataset/… – Milad May 16 '19 at 14:50
