Tehran area SRTM mesh ZipDive!  Download

File Description:
This terrain mesh scenery is centered on Tehran city. Ranging from 34.1N to 37.5N and 49.2E to 54.8E, it includes Elbourz moutain range as well as Caspian sea shores (28 meters below sea lavel). Based on SRTM Data (3 arcsec, 90m) and sampled to LOD9 resolution (76m) using Matthew Styles's program "SRTM To BGL v1.04". While only tested with Fs2004, this mesh should also run with FS2002. SRTM 3 arcsec dataset has numerous and sometimes huge void areas. But thanks to John Child's beautiful and powerful "Blackart" utility it's now easy to patch these areas with lower resolution dataset: I took the coupled interpolation method to merge SRTM 3-arcsec with SRTM 30-arcsec dataset when needed. This gives the best results, as patched areas with 30-arcsec data are blending naturally with surrounding 3-arcsec mesh. Of course the resolution of patched areas is quite poor, but still a bit better than the default LOD5 mesh. However, in exception of Demavend Peak, the SRTM data was quite good for this area and didn't need much patching so that the rendering is allways excellent.
