As found in the MSFS section of AVSIM there are a new NASA SRTM elevation release with edited data.What a big difference, now all the water area is flat ! :-)Scenery looks much better with this nwe elevation release - thanks to NASA.the link to the new data is:ftp://e0srp01u.ecs.nasa.gov/srtm/version2/here is a first demonstration of it inside Switzerland - Walenseethe old version http://www.agtim.ch/fu3/images/SRTM_V1.JPGwith the new data http://www.agtim.ch/fu3/images/SRTM_V2.JPGthe old chart http://www.agtim.ch/fu3/images/e0aoai_V1.jpgthe new chart http://www.agtim.ch/fu3/images/e0aoai_V2.jpg :-wave agtim

Thew new Switzerland is coming along nicely :-)Speaking of poor elevation data, would it be feasible to improve the Seattle region elevation? We have quite a few odd shorelines.Hans Petter

Hi Hans,Yes you can correct the shoreline using GeoTilesViewer md3 export of 60% of a tile and then correct it using GMax - there is a tutorial page for this http://www.agtim.ch/fu3/MD3.php3 redo the full area with the new SRTM_V2 data is too much work for the expected results and the mountain part of Seattle Region will not look much better afterwards - but it's technicaly possible to make it.It will become a must when someone (not me :-)) expand the Seattle region. :-wave agtim
