Hey everyone. I wanted to pop in here because I've recently started working with the GDAL (http://www.gdal.org/) for map reprojections. I have an account with the National Geospatial Agency and have acquired a bunch of Aviation Chart's in rpftoc format and am going to be reprojecting them and converting them to onscreen png for flight simulator use, but I really got a warm fuzzy about how I'm working with map data for my job finally. Anyone here ever do any GDAL work?

GDAL comes with some pretty neat tools, my favorite of which is GDALWarp, which can take images and reproject them...might be worth checking out.
