Dear Dr. Bunting,
My name is Sahar from CESBIO laboratory of Toulouse. I managed with my
collegue Tiangang to install the latest version of SPDlib.
We tried then, to read LAS 1.3 LiDAR files with python script
LASWaves2UPD.py:
"python LASWave2UPD.py -waves file.las file.spd"
but we got this message error :
Starting to process 18430 points
Traceback (most recent call last):
File "LASWave2UPD.py", line 1262, in <module>
obj.run()
File "LASWave2UPD.py", line 1210, in run
self.readLASWaves(lasHeaderData, inputFile, outputFile)
File "LASWave2UPD.py", line 381, in readLASWaves
wave_data = struct.unpack("=%db" %wave_size, wave_dat)
struct.error: unpack requires a string argument of length 256
We wonder if you have any idea about this.
We appreciate again all your help
Sincerely,
Sahar and Tiangang
