[gdal-dev] Convert TIF to BIL

[Bret Johnson]

Based on that, it looks like my program requires coordinates in decimal degrees and my files are not in that format.  How do I force the output into the correct (decimal degrees) format?

The program is made by SoftWright and is called TAP, which is used for radio propagation analysis.  The relevant parts of the error message are:

Note that 1 file(s) were found that were not indexed because of errors.  There could be errors in the data file(s), or these could be files that are NOT topo data files that the program tested to try to index and failed.

Like, I said, pretty generic and not very helpful.
