umm, that might not work -- r.info will still know the map is XY even if the location is changed to lat/lon. > - check resolution is correct (nicely "0:01:20") with r.info. > - zoom to area of interest. you probably do not want to reproject > entire planet. after zooming check resolution is preserved, > (g.region -p, maybe with "g.region res=0:01:20 -a" after zoom to fix) > and run "r.mapcalc cropmap=fullmap" to perform the crop. > > then from the lambert location run r.proj to pull the > cropped image across. > > there are some examples of this process in the GRASS wiki, > look at the "Global datasets" page. the above issue should be covered there; also check the mailing list archives. so your "easiest" solution is to create a "world file". see the GDAL JPG or GeoTiff format import page, or do a web search for instructions.
