Hi Glenn,

Bottom line: if you use VPB to build a terrain in UTM zone 32 (or whatever), you will need to do no coordinate conversion.

I'm currently doing some tests with some data I got from http://www.ngdc.noaa.gov/mgg/image/2minrelief.html (pretty low res, but I'm just testing). The problem I have is that the data's positions seem to be in latitude/longitude in degrees, and I'd like to convert it to what I'm expecting (meters). I'm not very familiar with the tools (I assume GDAL and/or PROJ can do this), so I'd appreciate a hand :-)

gdalinfo gives me this for the file I have:

Driver: EHdr/ESRI .hdr Labelled
Files: Hellobob_5209.bin
       Hellobob_5209.hdr
Size is 271, 241
Coordinate System is `'
Origin = (2.983333335000000,64.016665864999993)
Pixel Size = (0.033333330000000,-0.033333330000000)
Corner Coordinates:
Upper Left  (   2.9833333,  64.0166659)
Lower Left  (   2.9833333,  55.9833333)
Upper Right (  12.0166658,  64.0166659)
Lower Right (  12.0166658,  55.9833333)
Center      (   7.4999996,  59.9999996)
Band 1 Block=271x1 Type=Byte, ColorInterp=Undefined
  NoData Value=999999

So as you can see, ~(3, 56) to ~(12,64) in degrees.

I'd like to have that in meters in the right place on the Earth... How would I do that? On the gdal_translate man page I see the option a_srs overrides the projection of the output file, but I have no idea what the argument should be.

Thanks in advance,

J-S
