Hey everyone,
Not sure if any has come across this (I found it by accident), but there is a site where you can download 70m SRTM mesh - here is the blurb from the site:
"These are scenery files for FS2004, FS2002 & FS2000. The entire landmass of the earth between 60°S and 60°N is covered in 682 geographical sections. The resolution of the source files is three arc-seconds. The terrain mesh is sampled at 70m. However, see the README for a discussion on the relative accuracy of the source data. These scenery files were generated from preliminary SRTM (Shuttle Radar Topography Mission) data downloaded from ftp://edcsgs9.cr.usgs.gov/pub/data/srtm/. The complete scenery set is about 8.27GB"
I use FS Terrain for the USA and Europe, which is 76m, so this stuff is 6m of more detail!! You can download a reference map, which I use to mark off which areas I have downloaded.
Here is the link:
