 This agrees with my analysis using 1.3.0 on F10. Agus said that the file
 came from 1.4.0 on Windows. If the interpolator tool/plugin only produces
 ARC ASCII  files, then we do need to find out where the GTiff came from.
 The interpolator is not the culprit here.

 The interpolator-generated Arc ASCII raster that I made and read into R
 using GDAL was imported correctly. I would, however, give a default square
 cell resolution in the interpolator menu, which would mean that the GDAL-
 specific DX/DY tags are not used (using a check box to revert to current
 behaviour). Further, it would be great to be able to set the power for IDW
 from the menu (maybe it is there, but I didn't see it).
