Hello everyone,
I am looking for any codes, suggestions, or recommendations that may save me
unnecessary development time. (I hope somebody out there has already done
this).
I need to import a "BIL" format file to a GRASS raster cell file. "BIL" is th
e
format of the 30 arc second DEMs (referenced in lat/lon) available at
edcftp.cr.usgs.gov (/pub/data/30ASDCWDEM). The README associated with these
files (South America), indicates that some of the ancillary files in these
archives can be read by ARC/INFO's Image Integration application. I do not
have access to ARC/INFO. Also, I have not been able to identify any "readily"
available means of importing them to GRASS as is. Perhaps someone else has.
If someone has already developed some sort of translation code for these files
that results in r.in.ascii or r.in.ll compatible files, or some other
GRASS-convenient format, I would very much like to obtain it. Otherwise, I
would very much appreciate suggestions and pointers to ease the development
and
verification burden in creating such a translator.
Any comments? Please let me know.
Thank you sincerely,
Jason

I think the uncompressed GRASS raster format for cell files is BIL. At least
I have been able to use one-byte (less than 256 categories) uncompressed
GRASS files in programs such as Arc View using the .bil extention and a
header file with registration information. As I recall, I have also been
able to import SPOT files in a BIL format using the i.tape.other routine.
