Hi all,
This is my first submission to the list, but I've been around for a while.
Not sure if this is the correct list to post about this; if not, please, let
me know and accept my apologies.
I've been able to successfully build FlightGear without much pain - just a
couple of tweaks, as I'm working on a Windows XP / Visual Studio 2005
Express environment, and everything runs fine.
However, I've tried also the TerraGear package, a completely different
story. My interest is not just to compile it, but to update my FlightGear
scenery with more accurate data. Specifically, I'm trying to improve the
terrain elevation data and the surface textures to make them more realistic
around my area of interest (north-west of Spain). I've got elevation data
from SRTM Data (http://srtm.csi.cgiar.org/SELECTION/inputCoord.asp), which
gives you data for a relatively large area into one unique file. It's a very
convenient source, as they have already done the hard work for filling voids
with interpolated elevations. As this is not the same source TerraGear is
programmed for, I was planning to reprogram the file interface section in
order to adapt it to my source.
After several attempts and many hours trying to compile TerraGear, I have
finally made it for the chop utility. However, as the data file is different
from the one used in the original implementation of hgtchop, I will need to
modify the code. For that reason, I ask you some specific information I'm
not able to infere from the code: What is the size (lat-long) of elevation
files generated by the original code? Is it important to maintain the exact
same size for the rest of the scripts/utilities to run properly? If the size
is important, should it be an exact number of data points or an exact
physical coverage of earth? And, finally, is there any document/readme with
the intermediate and the final scenery file formats? This would help me a
lot, although I know I could get this info from the code itself.
By the way, I have also tried the FGSD (Scenery Designer), but I'm not able
to make it work; it does start, but no way to import FG scenery data without
a crash.
Thanks a lot in advance,
David
