I'm trying to import an ESRI flt raster into Grass 6.3.cvs using r.in.gdal. Using fresh gdal 1.4.1 from today, and fresh Grass 6.3 cvs update from today on Ubuntu 7.04 Beta.

  • status changed from new to closed.
  • description changed.
  • component changed from default to GDAL_Raster.
  • version changed from unspecified to 1.4.0.
  • milestone set to 1.4.2.
  • keywords set to ehdr.
  • resolution set to fixed.

The problem is related to initialization when the NBITS keyword is missing from the .hdr file. In 1.4.0 a bunch of new code was introduced for NBITS < 8, but it also added a dependency on having the keyword present.

The workaround is to add "NBITS 8" in the .hdr file.

Fix is to default to 8 in the code. The fix has been committed in trunk, and 1.4 branch and it should be released in 1.4.2.
