Hi, I have raster file generated by ENVI from LAS 1.1 file. I try to subset the data via ROI and I encounter problems. Here are the step I'm doing: 1. Open the raster 2. Define a ROI 3. Select the "subset data via ROI" from the LiDAR tool menu 4. Select the LAS file that originaly was used to create the raster 5. Select the ROI option, set to the correct ROI, select the output name and start the process 6. Got the following warning/error : "The selected files do not contain any points within the specified area" How this could be possible since the data set is the same for the LAS raster and the LAS file ? Any clue on this ? Cheers.
