[GRASS-windows] 1. Convert from Meters to Degrees (Louis Becker)

[Louis Becker]

Hi Markus, Niel and others

I have unzipped my original GeoTiffs again and it seems that I lost (or
did not unzip) my ".tfw" before. It appears that this file contains the
Geo-referencing information because the import is working fine now.
Thanks for your responses and help.

Regards
Louis

Hi

I am fairly new to Grass and GIS in general and suspect that there is
quite and easy answer to my question, but I have searched and searched
and just cannot come up with a solution. Please help.

I have a GeoTiff file that has its Lat/Long in meters. I would like to
overlay it on a layer with Lat/Long in degrees. The rest of the
projection/datum info is the same. If I just do a strait import, it
assumes that the Lat/Long is in degrees and of course it is displayed in
a total the wrong location in relation to degrees. How can I convert the
file in meters to be projected or imported in degrees? I searched and
searched, but can't find a solution.

Louis,

not sure what "Lat/Long in meters" is... can you please post the output
of gdalinfo on these maps to the list?
