Lewis, you can use d.what.rast to accomplish this.
I have produced some raster files using Grass tools and I want to
be able to look at the raster file and, as I look at it, click on
positions within the displayed raster and have the value at that point
displayed, say, to standard out or a window or just anywhere that I can
see it. I want to be sure the raster values produced are really doing what
I think they are. Any suggestions?
