It involves a GPS, two bits of string, a barometer and a long weekend
walking in circles around every hillside in the country...
In reality, it's fairly easy, and is based on using SRTM data and
gdal_contour to create the shapefiles, with a few basic scripts to tie
everything together. I'll make a page on the wiki with all the code to
get from NASA to the rendered contours on it the next time I have an
hour free.
Cheers,
Andy
