[GRASS-user] scanned map, north not up

Hello All,

I have been using GRASS with scans of my maps, to make GeoTiff files to use on my smartphone.

Most of my maps have north up, I’ve been using UTM zone 18 and have had no trouble.

Two maps I am working with now have north not up, and upon georectifying in GRASS become tilted. Exporting these to GeoTiff produces large wings of no data on either side. Is there a way for me to use a different projection in GRASS to have north match the direction on my printed map? Or is GRASS not the right tool for this problem?

Thanks,

Steven
