Odd 1st-4th return values change after tiling #7

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Tiling las-files (4 return airborne lidar flightlines, up to 6gb size, only 
class 1)
2. Retreiving header info
3. checking number of points, 1st returns, 2nd returns, 3rd returns, 4th returns

What is the expected output? What do you see instead?
number of points should be the sum of all returns
instead, number of points always/for all files equals 1st returns whereas 2nd 
return is always/for all files is 3251850, 3rd return is 131078, and 4rth 
return is 1153.

What version of the product are you using? On what operating system?
Win 8 64 bit, ENVI 5.1, bcal envi extension 1.5.2

Please provide any additional information below.
If I retrieve the header information before tiling, everthing seems fine. But 
the files are so large which neiter ENVI nor ArcGIS/QGIS appreciate so I would 
prefer tiling. I don't want to decimate, maybe subsets are an option.
