I believe I have a problematic .las file. It is in the same set as the other problem children. All the other .las files were processed ok with the latest liblas code.
Mateusz: may I upload this las to your site? on eliminating classes I get: "Not able to fetch a point. LASReaderH is invalid: detail::liblas:: read_n input stream is not readable (3) from method LASReader_GetNextPoint" on repair, I get "Problem creating LASWriterH object for append: Detail::liblas::write_n: output stream is not writable (3) from method LASWriter_Create" on the repair it also throws up a bunch of various messages: "User: 'LASF_Projection' - Description: 'Projection Info' ID: 102 Length: 64" Mark Mark On Wed, Sep 30, 2009 at 10:02 AM, M S <[email protected]> wrote: > Confirmed fix.
