Re: Airports on tombstones and SRTM30 Data

I've managed to partly answer my own question - we use
SRTM-3 data for Eurasia right?

I've tried using hgtchop to parse the data, but I keep
getting the following error:

0:0, 0:7
width = 0.125 height = 0.125
min = 0,3150  max = 450,3600
start_x = 0  span_x = 150
start_y = 1050  span_y = 150
  ERROR: bucket at least partially outside HGT data
range!

Any ideas? Do I need to change some SimGear constants
for the bucket size?
