Hello,
thanks for the example file ! It is very interesting. I have quite a stupid
question to ask though. For the elevation data, you use a "pgm" file. Do
you generate it "by hand" from the elevation data you get from the given
datasource (USGS, NASA, etc...) ? Are there any utilities to manipulate the
..hgt, .dem ... files and convert them to pgm files ?
Thank you for your answer and thanks for your GREAT web site

The ETOPO2 data set used in the example can be easily converted to PGM 
by adding an appropriate header:

P5
10800 5400
65535

or using Imagemagick.  A lot of formats can also be converted using the 
GDAL tools.
