I'm not at my GRASS, isn't there a small dropdown menue to choose the raster?

This wxGUI tool is nice to change pixels or small areas in a raster.

To change larger areas in a raster, there may be other workflows.

E.g. build contour lines, select the appropriate which delineate :+/- your hill, build an area from the contour line to have the footprint of the hill, then rasterize this area with the same heigth and r.patch it back to your DEM or interpolate it with the appropriate tool as you already mentioned.

Kind regards

I'm able to start the "Raster Digitizer" tool, but then cannot do anything.
A second toolbar opens and the mouse cursor changes to a pen (edit mode?), but when I click on the map, I get a dialog that says, "Please select the first raster map". I'm not sure where/what/how to select this, and I have been unable to find documentation about this new tool.

How would one go about removing a hill from a DEM? I imagine drawing a new raster by digitizing an area, then using it to set the hill region in the DEM to NULL, then interpolating the DEM to fill in the now-removed hill. Does this seem like a reasonable workflow?

Thanks,

Yes of course. For some reason GMail defaulted to "reply" instead of "reply to all"

How will you do visually raster editing on the CLI?

I typically call d.rast and d.vect and etc. from the CLI, and when first trying d.rast.edit did that from CLI too. Yes those commands do bring up a window. Thanks for your advice below, I will look into the larger GRASS wxGUI for the transparency.

Anyway, I expect this will help, but may not be a complete solution... I'd like to be able to examine multiple rasters while editing 1 (or >1). Something like g.gui.mapswipe, but with more linked maps, would be good. It seems this needs to be a custom tool I write, perhaps using the Python API.

Thanks again for the hint about transparency,

   -k.
