Problem: I have a set of LAS files that doesn't display in Arcmap.
Details: I try to use LAS to tin in Arcmap to convert my LAS points to a TIN. However, when browsing to the folder with the files, it doesn't recognize them as LAS files: they do not show up even if I choose *All.
I have tried a couple of conversion tools available in LAStools, but without success. I have also tried to use FME to convert them to shapefiles, but the only thing I get is the bounding rectangle.
I seem to remember hearing something about this being a problem in Arcmap 10.1 with data that has been extracted using FME (which I'm not sure these are, but still), but now I can't find anything about it online.
Has anyone else encountered this? Any possible solutions, workarounds, or at least a bug report?
To answer @Andre Silva's comment: I'm trying to convert the point cloud to a raster to do hydrological analyses with it, e.g. calculate catchments etc. I have used other las files without issues before, so my interpretation is that this problem is specific to these files. As to the exact details of the files, they're <50 MB .las files that's been filtered for ground points only.
