Yes, I was awared of this switch but I prefered to understand why the error arises. Would it be possible to know the reason? > As an aside, there is a python script (spdbuildmergecmd.py) which you can use > automatically build you spdmerge commands. I saw this python script browsing the source but I did not really understand it that much, not even with the manual. I will give it another chance. > With the other errors I don't know, I would need to have a look at the files > and try to reproduce the error and debug the code. Following the merge what > bin size are you translating your files to? Good point! I used the bin size by default to translate from las to spd, in fact spdinfo says the files Bin Sizes are: Gridding [xSize,ySize] Bin Size: [501,501] 1 Surprisingly, the header of the merged file is: Gridding [xSize,ySize] Bin Size: [0,0] 0 I guess that is why spdinterp and spdpmfgrd do not work properly. The question now is to know why Bin Size is 0. > If you are processing large datasets you might find it quicker and easier to > use the tiling commands which splits the scene into tiles (with an optional > overlap between tiles) which you can then process independently Yes, I know that. As a matter of fact, my las files are actually tiles. I was just... testing ;) Cheers, Roberto -- Roberto Antolín http://twitter.com/#!/tolanss ------------------------------------------------------------------------------ Introducing Performance Central, a new site from SourceForge and AppDynamics.
