The others were generated with GDAL 1.7. I downloaded and installed Erdas ViewFinder and I noticed that the files generated with 1.7 does not open on that software or ArcExplorer for that matter. The ones generated by 1.6 work just fine. It looks like some changes on the HFA driver created a bug. I was going crazy thinking that the problem was with GeoRaster but those test are just Geotiff to HFA and we can clearly see the problem. It looks like an WKT issue: {{{ Files: n00w075e1ori_16.img Size is 281, 281 Coordinate System is: PROJCS[""UTM Zone 18, Northern Hemisphere"", GEOGCS[""WGS_1984"", DATUM[""WGS_1984"", SPHEROID[""WGS 84"",6378137,298.2572235630016], TOWGS84[0,0,0,0,0,0,0]], PRIMEM[""Greenwich"",0], UNIT[""degree"",0.0174532925199433], AUTHORITY[""EPSG"",""4326""]], PROJECTION[""Transverse_Mercator""], PARAMETER[""latitude_of_origin"",0], PARAMETER[""central_meridian"",-75], PARAMETER[""scale_factor"",0.9996], PARAMETER[""false_easting"",500000], PARAMETER[""false_northing"",0], UNIT[""Meter"",1], AUTHORITY[""EPSG"",""32618""]] Files: n00w075e1ori.img Size is 281, 281 Coordinate System is: PROJCS[""WGS_1984_UTM_Zone_18N"", GEOGCS[""GCS_WGS_1984"", DATUM[""WGS_1984"", SPHEROID[""WGS_1984"",6378137,298.257223563]], PRIMEM[""Greenwich"",0], UNIT[""Degree"",0.017453292519943295]], PROJECTION[""Transverse_Mercator""], PARAMETER[""latitude_of_origin"",0], PARAMETER[""central_meridian"",-75], PARAMETER[""scale_factor"",0.9996], PARAMETER[""false_easting"",500000], PARAMETER[""false_northing"",0], UNIT[""Meter"",1]] }}} I can see some changes made by you and Even: http://trac.osgeo.org/gdal/browser/trunk/gdal/frmts/hfa?order=date&desc=1 Do you know of any change that might has caused that issue?
