Greetings<br><br>I have a raster image of 3000 x3000 cells. But only a part of it (70x30) have valid pixels.<br>When I export it with r.out.gdal I obtain slightly different results if I export with g.region rast=image and g.region rast=image zoom=image . And this difference is "expanded" when I try to reproject both maps to WGS84. My question is: which is the best approach? use a region for all image or a region just for "valid pixels"?<br>
THanks<br>Helena<br>
