#1734: support lat long rasters with half pixel overlap outside -180W,90N,180E,90S
-------------------------+--------------------------------------------------
Reporter: karme | Owner: grass-dev@…

-------------------------+--------------------------------------------------
Just wanted to import gmted2010 data having extent to the south of 90d 0'
0.50"S. I don't see a clean fix. One workaround is the throw away one row,
but then half a pixel is missing to 90S.
(see also: http://grass.osgeo.org/wiki/Global_datasets describing the same
problem with etopo1).
Using grass 6.4.2 r.in.gdal does the wrong thing (TM). It assumes there is
a rounding error and adjusts the south extent to -90S and displays the
warning:
"WARNING: Fixing subtle input data rounding error of south boundary
(-0.000138889>1e-06)
"
