Nope, that didn’t help. Same error message. From: Cainã K. Campos <rupestre.cam...@gmail.com> Sent: Wednesday, March 11, 2020 10:54 AM To: Bret Johnson <bret.john...@utcg.com> Cc: gdal-dev@lists.osgeo.org Subject: Re: [gdal-dev] Convert TIF to BIL
Bret, maybe gdal did not recognize source projection, try to run again with -s_srs EPSG:XXXX, where xxxx should be the epsg code for your projection. Like: gdalwarp -s_srs EPSG:XXXX -t_srs EPSG:4326 input.tif output.tif On Wed, Mar 11, 2020 at 1:39 PM Bret Johnson <bret.john...@utcg.com<mailto:bret.john...@utcg.com>> wrote: Tried your recommendation of GDALWARP, and received this error message: ERROR 1: Too many points (529 out of 529) failed to transform, unable to compute output bounds.

Check if your .blw matches the example in the link, if not you can easily create one with a .txt file renamed to .blw. I believe that the .tfw should be renamed to .prj as described in doc, and check if formats match also in the .prj generated with documented In order to reproject raster to decimal degrees you should use gdalwarp with the -t_srs flag, and choose a degree projection like EPSG:4326, you may do it before translating to .BIL , like: gdalwarp -t_srs EPSG:4326 input.tif output.tif Caina On Mon, Mar 9, 2020 at 8:23 PM Bret Johnson <bret.john...@utcg.com<mailto:bret.john...@utcg.com>> wrote: Based on that, it looks like my program requires coordinates in decimal degrees and my files are not in that format.
