Hi, I would like to ask some questions about new 3D Lidar Viewer. 1) I am not able to open lot of files, that I was able to open in ENVI 4.7 with Lidar Toolkit - for example dataset, that are in folder LIDAR Visualisation - demo dataset that can be downloaded from ITT VIS pages (file 42124B3317.las) and also *.las data from LiDAR demo skript called las_sample_1. All these files I am able to open in ENVI 4.7 with Lidar Toolkit, but with ENVI 4.8 new LiDAR Viewer I have only black window of Lidar Viewer and nothing happened. I didnt get "Process Data dialog" as should open according to help. 2) In Lidar Toolkit ENVI 4.7 I created las file from ASCII and this file I was able to open in new 3D Lidar Viewer - but this is kind of uncomfortable, because in ENVI 4.8 I am not able to convert ASCII to las file even in new 3D Lidar Viewer. Is there any possibility to convert ASCII file to *.las file with ENVI 4.8? Thank you very much. Lucie
