Hi All,What a great sim. Love it:) Well done to all the folks who worked/are working on it.I have been knocking out a little dynamic map tool (using a 4GL called IDL) to help me find the various airfields. I got it to read the airport locations file (I plan to progress to the runways file later) and plot them as symbols on my map. But here's the thing - they're in the wrong place! If I start the sim at, say, London Heathrow my HUD tells me 51 28.4 N by 0 26.2 W, but the file line for London Heathrow is:A EGLL 51.470765 -0.454340 80 CYN London HeathrowWhat am I doing wrong? Do I have to transform the coords in some way, or am I reading the wrong file?Any help welcomed!Many thanks,Dave

Hi Dave,It looks like the HUD is showing degrees + decimal minutes, but the airport file is using decimal degrees - 28.4 / 60 probably comes out at about 0.47 if you see what I mean. Have you tried Atlas by the way (an airport and navaid viewer for FlightGear) - http://atlas.sf.netCheers - Dave

Hi DaveL,Yup, that's it alright! I just noticed the same myself. The problem (apart from my stupidity) was that I am using the coordinate output files as a transfer mechanism which appear to show the coordinates as the lat * 100, where in fact it is degrees*100+minutes. So far, it seems as if the minutes are *really* decimal, not minutes.seconds, but I'll have to check more to be sure.I took a look at Atlas, but it seemed only for Unix (I'm on XP), so I thought I'd knock something together. If there's a Windows port I'd be interested - not sure if I have time to attempt the port myself at the moment.Cheers,Dave

You can find windows binaries of a recent snapshot from the following link:http://sourceforge.net/mailarchive/forum.p...3&forum_id=3236The next Atlas release should have Win32 binaries available for download.Cheers - Dave
