[kepler-dev] GIS/GDAL question

[Dan Higgins]

Hi All,

    Any GIS/GDAL experts out there?

    As part of the ENM/GARP workflows, we need to read and re-project 
some *.bil raster files. We are using some GDAL code in actors to do 
this. The problem is that one of the *.bil input files is specified with 
NBITS=32 in the *.hdr file. GDAL apparently assumes that NBITS=32 
corresponds to 32-bit floating point data, but some other applications 
assume it is 32 bit INT data!

    The data is apparently 32 bit INTs. Is *.bil data always INT data? 
(It allows 8 and 16 bit data which are integers; I see no way of 
specifying what 32 bit data represents.) Is there any way in GDAL (eg 
GDALWARP) to set the assumed input datatype? (i.e. tell GDAL to assume 
INT rather than FLOAT?)

Dan
