I'd like to use GDAL to write raster files containing a NoData value, in a binary format that can be recognized by ESRI software (ArcMap, etc). I've tried several experiments and haven't come up with anything that works yet. Geotiff seemed like an obvious choice, but apparently ESRI uses a different convention from GDAL in geotiffs for storing the NoData value. I also tried ERDAS Imagine format, but it seems that GDAL can't write the NoData value in an HFA file.
<br><br>It doesn't matter to me which format it is --- I just need support for one band, georeferencing, and a NoData value, in a format that I can write with GDAL and then hand over to someone who uses ArcMap, so that when they load the file, ArcMap correctly understands the georeferencing and the NoData value.
<br><br>I think it will work with AAIGrid (ESRI's ascii grid format), but it is huge. Does anyone know if it is possible with one of the binary formats?<br><br>Thanks,<br><br>--Mark<br><br>-- <br>Mark Phillips<br>Geometry Technologies LLC
