Point Cloud Generation of XYZ files
« on: August 26, 2013, 11:40:26 PM »
Can someone tell me what the specific columns mean on the XYZ generated point cloud are? I get the east (y), north (x), and elevation (z), but the other 4 columns are unknown to me. Also, when I created the point cloud in the LAS format, my other software gave an error message with regards to the numbers assigned to the colour red. Any idea if or how I can configure the creation of the LAS or the XYZ files?

x, y, z, red, green, blue, normals (pitch roll and yaw)

If you are only wanting an xyz point cloud uncheck the boxes that say 'point colors' and 'point normals' during export.  If your post-processing software can accept these values then leave them checked, up to you?  I personally do not use the point normals but I do utilise the rgb values.

As for the las file... not too sure??  I think I may have encountered that error before but I cannot remember what the problem was?
