Hi Nicholas,

your assumption regarding your source UTM Zone beeing UTM 32N is wrong.

Your coordinates are from Tunisia. And Tunisia is UTM 32S, not UTM 32N:

But as you can see here EPSG:32632 is the right result of a conversion from
UTM Zone 32S to EPSG:

Question remains why your coordinates from Tunisia are displayed in Algeria.

I wonder if it is OK to just use EPSG:32632 as a projection for your data,
or if one would have to do math on the coordinates to.
After all your coordinates have been recorded in *WGS84, UTM 32S.*
