Hello,
I need to import a set of raster data in ASCII xyz format, with the
coordinates referring to the southwest corner of the grid cell rather
than the center as is the convention. I can think of a number of clumsy
ways to solve the problem by scripting, either involving importing the
raster first with an incorrect region definition, or by batch editing
the text files, but am wondering if there is an elegant way to do this.
For example, adding a simple +(resolution / 2) offset to both the lat
and lon coordinates would do. I already tested and simply using the
correct region definition and hoping that the data falls into the
correct grid cells does not work.
How about r.region (not g.region) with something like:
r.region YourMap n=n+[res*0.5] etc
?
