INTRODUCTION
After many years of SRTM (and its limits, such as availability of data just
between 60° North and 60° South as well as resolution over all of just 76m) we
leave it behind us and set foot to new shores. New much better data sources have
been discovered and used. So this is the first version of FS Global to offer a
WHOLE world coverage including areas not covered by SRTM such as Antarctica,
Greenland, Iceland, Russia and Scandinavia to name a few. In order to reduce
data size we have selected the appropriate resolution for each area. It does not
make sense to render the Great Plains in the USA or northern parts of Germany in
a LOD 12 (9m) resolution. Flat is flat. Higher resolution here is not visible to
the eye in Flight Simulator. It just needs more space on your harddrive and more
time to load in FS. Bear that in mind when you read about resolution on this
website and others.
Below is a list of just a few improvements over pevious versions of FS Global (so you get what was in the previous version PLUS that! e.g. we do not list the Alps in LOD 12, as they already were LOD12 in FS Global 2008)
LOD12 (FS-Mesh- and sourcedata in 9m resolution!) for Hawaii (complete) and the southwest of the US, south of 38°N and west of 108°W (ca. Mesa Verde -> Point Reyes)
High Quality Coverage of Northamerica (and p.Canada!): nationwide LOD11 (19m).
Greenland, Iceland and Scandinavia in LOD 9 (76m; standard SRTM resolution)
additional high resolution areas in Europe in LOD11 (19m): High Tatra, Scottland, Hardangervidda (Norway)
huge areas in the north of Russia in LOD9.
Antarctica in LOD8
sophisticated new algorithm for correct views of ridges and peaks (most of them sould have been higher and will now be nearer to actual value)
new algorithm for reducing irrelevant data for higher data compression
new algorithm for finding and correcting errors
Airport-Patches for prominent problem areas
a tool for the user to correct wrong airport elevations
