HiIm doing a final year elec & comp engineering project which requires that I use a flight simulator to run a real time topographical SAR radar simulator.Im interestied in using flight gear and I was wondering if there are any FG enthusiasts out there who are willing to help me out.Basically I need to know what DEM(digital elevation model) FG uses. The radar simulator uses simple square shaped maps stored as a simple list of co-ordinates.I will be coding the project in Linux. My lecturer is keen on the Knoppix distro but Ive been having a issues with it recently.Basically Im asking for any help whatsoeverThanksJono

Hi,FG uses a mix of data sources to build terrain files (srtm, vmap, etc).More accurate information can be found here : http://www.terragear.org/news.html
