Southern hemisphere projections for Landsat upsets GRASS

The Landsat GeoCover data use a non standard UTM projection for the Southern hemisphere.

All you need to do is assign the Northern projection to the Southern images and it will be in the correct location and you will be able to reproject the images on the fly.


Problems with southern hemisphere projections for LANDSAT data in GRASS/GDAL seems to exist since long. Here are some discussions in this regard:

  1. [GRASS5] Problems with UTM/southern hemisphere
  2. r.in.gdal unclean import of southern UTM zone
  3. Win7 GRASS 7 & i.landsat.toar, here there's a mention as follows in question

I have taken care to reproject the images properly since there is incorrect metadata for Landsat in the southern hemisphere.

You could also try contacting USGS directly for information via this web form.


USGS Landsat imagery is supplied with a Northern Hemisphere UTM projection. Scenes that are in the Southern Hemisphere have negative Y coordinates, this means they will display in the correct location south of the equator. Basically, don't worry about it. If it bothers you, reproject your data.
