Gary -- can you try using las2las to cut out smaller sections of your file until the problem goes away and find the "magic" point at which it fails? Actually, I wonder if las2las will even work on a file that large. That would be enlightening. I would guess a 32-bit overflow is occurring. So start, perhaps, at 2GB and keep doubling. Michael D.

I imagine you'd be able to do the same easier than I could send you the file. I do get an error in libLAS's cached reader system when reading points from that huge file the second time. Somehow it seems the istream becomes invalid. I haven't been able to figure out why. It reads fine the first time and then part way through the second time when I am seeking specific points and then reading a sequence of points that follow. The process works fine on smaller files of only a milllion or so points. -Gary -- View this message in context: http://liblas-developers.431198.n3.nabble.com/Liblas-devel-Need-a-very-large-LAS-file-tp1780142p1783187.html Sent from the libLAS Developers mailing list archive at Nabble.com. _______________________________________________ Liblas-devel mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/liblas-devel
