[Flightgear-devel] ASTER DEMs
Hi guys! I downloaded ASTER DEM and play with it Nice resolution (30m) but there are so many holes to use it So fightgear/terragear gurus maybe you tell me is there in dem library some tools to approximate aster dem data with gtopo30 data to eliminate holes? Another question: now we have tile size = 1/8 degree. but when you deal with this high resolution data you have to load smaler tiles to have good frame rate where should I search terragear/flightgear code to have tile size 1/16 or 1/32 degree. here as I got another problem tile names. and finnaly about LOD in tiles. Is there any plans or thoughts to implement it? Thanx in advance Bye ___ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel

It is currently commented out but see src / lib / dem interpolate() It may still work and in any case shouldn't need much to fix there is also an Interpolate in the Lib/Array class also commented out Another question: now we have tile size = 1/8 degree. but when you deal with this high resolution data you have to load smaler tiles to have good frame rate where should I search terragear/flightgear code to have tile size 1/16 or 1/32 degree. The US scenery is made with 30 meter DEM's so things should work OK the least squares fit process removes many points and is 'tunable' if need be Norman ___ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel
