#1734 new defect

support lat long rasters with half pixel overlap outside -180W,90N,180E,90S

Description

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)

"
