[GRASSLIST:974] Re: [GRASS5] How to make a geotif?

[Travis Kirstine GIS Tech]

I often use FWTools which includes gdal and when writing a geotiff I use the
creation options "PROFILE=BASELINE",  "INTERLEAVE=PIXEL" and write a
external worldfile with "TFW=YES".  I'm not sure if all these creation
options are available in GRASS but if so I would give them a try as well.

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
