I'm trying to plot realtime GPS over a satellite image in QGIS 1.8. The GPS data is coming in as NMEA lat/lon from a Garmin Etrex. This works when the image is in WGS84 lat/lon projection and therefore the coordinate systems match.
Unfortunately, I will be using this in high latitudes and WGS84 becomes unusable. I'd much rather have the image in something like UTM 24N or polar stereographic.
Does anyone know a way to get the GPS to plot in the right location?
I don't seem to be able to change the coordinate system that the GPS outputs, only the on-GPS display. Suggestions for either Linux or Windows welcome!
