[Flightgear-devel] What about 3 arcsec Eurasia Terrain data before the release of FGFS 0.9.4?
Since Oct 2003 there is a 3 arcsec SRTM Terrain data for Europe and Asia on the usgs.gov ftp server available. ftp://edcsgs9.cr.usgs.gov/pub/data/srtm/Eurasia/ I think we should create new scenery files for the Europe and Asia area based on this better 3 arcsec SRTM Terrain data before we release FGFS version 0.9.4. The current available scenery for Flightgear for Europe and Asia is still based on the low detail 30 arcsec SRTM Terrain data.

You'll be disappointed - it's not as accurate as you'd hope, and while it has a lot more shape I'm not convinved by its absolute accuracy - there are still airfields on embankments and in trenches (and checking the airfield elevations shows them to be correct). Ok, but at the location where i live i do allready have the airfield (EDGM) in trechnes when using the old scenery data, but the hills around my city would be a lot more accurate. I allready tested that with a STRM Terrain viewer. The hills do look much more realistic with the new 3 arcsec data: http://www.dgadv.com/dgtv/ So we allready have the problem with airfiels on embankments or in trenches.

OK, then I guess a scenery rebuild is the next job after getting 0.9.4 released, and packaged. As it's not in the base package it doesn't need to hold up the release though. I've got all the data downloaded and at least part processed ready to build the scenery. -- Jon Stockill [EMAIL PROTECTED] ___ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel

..has anyone played with the lower detail 30 arcsec SRTM Terrain data, _and_ the new higher detail 3 arcsec data, _mixing_ the data, to try produce even higher detail than the 3 arcsec data? I mean, both data sets_are_ correct. -- ..med vennlig hilsen = with Kind Regards from Arnt... ;-) ...with a number of polar bear hunters in his ancestry...

I mean, both data sets_are_ correct. I'm not sure how you'd end up with higher-level detail. For every 100 points in the 3 arcsec DEM, there will be one point in the 30 arcsec DEM, presumably equal to the highest of the 100 points (but I'm not sure -- Norm can probably fill us in).
