I've been mucking around trying to build my own scenery for the last couple
weeks, with a VAST amount of help from Geoff McLane. I've got it all working,
and have been able to generate my own scenery.
However, the elevation is coming out all messed up. Geoff has some photos of
how it has come out available on his site:
http://geoffair.net/tmp/cullam-01.htm
Almost all the land data is appearing completely flat, at -9999m. There are a
few pieces of land that appear at sea level. All airports are at sea level.
I'm working on the scenery for the island of Newfoundland. I'm using the DEM
data available from
http://geobase.ca/geobase/en/data/cded/index.html\, which has a resolution of
about 30m. According to the Terragear tools, this data is in the correct ASCII
format, and is good to go for demchop.
After running demchop on about 380 of these files, the folder containing the
chopped elevation data is 131.1 MB.
I then run genapts on my apt.dat file which was modified to include airports
that aren't in the official apt.dat, and to correct their layouts. Again, there
don't appear to be any problems.
For my shapefile, I'm simply using the standard North American vmap0. This
appears to have been prepared without incident.
And then I run fgfs-construct. After the construction is done, my total folder
size for everything just generated is 7.1 MB. This has GOT to be where the
elevation data is disappearing, but I have no idea why. Obviously, there are
massive ammounts of specifics that I could get into, but then this question
would be huge and complex. So all I'm asking here is, does anybody have any
idea where I should start looking to figure out where this went wrong?
