Probably a stupid question but, which would be a higher level of realism, a 30M mesh or a 76M mesh. Also the 30 has a LOD of 10 (I assume this means level of detail) and the 76 has a LOD of 9. Lastly in case you don't know where I'm going with this, Rob Gainer has come out with a ton of new mesh's, I've been installing them all and really like them, however he just released one for Colorado. I already have the mesh for Colorado that came out a few months ago called Real Terrain. I just don't know which one to use for Colorado. I don't know if Rob's would "join up" good with Real Terrain. You know what they say, "There aren't any stupid questions,,, only stupid people". lol. B Bjorkman CFI

30m is more accurate. It samples elevation every 30 meters as opposed to every 76 meters. Check out this link for more info:http://www.fs-traveler.com/welcome.shtml

Thanks for the link and the info. BBjorkman
