[GRASS5] How to make a geotif?

GRASS GIS GRASS GIS developer

We’re trying to make geotifs of DEMs. So these these will have signed, floating point values. We’re having trouble making a geotif that other programs can read, especially ArcGIS and Imagine.

I’m using r.out.gdal.

Any suggestions on how to properly create a nice generic, portable geotif?

Thanks

Michael,

the manual of r.out.gdal contains this note:

NOTES
When writing out GeoTIFF format for users of ESRI software or
ImageMagick, the band
interleaving should be switched to pixel interleaving using
createopt="INTERLEAVE=PIXEL" .

Type will be Float32, I guess.

Hope this helps,

Markus
