CDED (usgs) wrong extents north of 68°

[matt.wilkie@…]

The cded export screws up north of 68° and exports the west half twice.

gdal_translate --optfile yt_cded.opt -co NTS=117d12e \
-co InternalName=117d12DEMe dem 117d12_e.dem

gdal_translate --optfile yt_cded.opt -co NTS=117d12w \
-co InternalName=117d12DEMw dem 117d12_w.dem

East:
Upper Left  (-140.0002083,  69.7501042) (140d 0'0.75"W, 69d45'0.38"N)
Lower Left  (-140.0002083,  69.4998958) (140d 0'0.75"W, 69d29'59.63"N)
Upper Right (-139.4997917,  69.7501042) (139d29'59.25"W, 69d45'0.38"N)
Lower Right (-139.4997917,  69.4998958) (139d29'59.25"W, 69d29'59.63"N)

West:
Upper Left  (-140.0002083,  69.7501042) (140d 0'0.75"W, 69d45'0.38"N)
Lower Left  (-140.0002083,  69.4998958) (140d 0'0.75"W, 69d29'59.63"N)
Upper Right (-139.4997917,  69.7501042) (139d29'59.25"W, 69d45'0.38"N)
Lower Right (-139.4997917,  69.4998958) (139d29'59.25"W, 69d29'59.63"N)

In this example east top left should be 139.5 (plus/minus the cell offset)

I've forgotten the rationale for why this is "wontfix". Can you refresh my memory? thanks.

Matt,

I don't think this is wontfix - it is just not followed up on. If you can provide a dataset, and control file that goes with the above commands, I'll try and look into this soon.
