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 hard drive 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 previous
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
source data 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 North America (and
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, Scotland, 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 should 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 For FS2004 and FSX. |
