So, two questions:
1. How can I identify specific 1m x 1m raster map cells based on the
location of a vector map point? Changing opacity of the topmost vector map
does not allow me to query the underlying raster map. With the raster map
on top of the z-stack I cannot accurately identify the raster cells that
need to have their elevations changed.
Answered this one myself: zoomed in to the vector point neighborhood,
found a nearby cell of a different color, and located the 4 cells covered by
the vector point. Recorded easting, northing for each.
2. Once I have the proper information to specify specific cells,
r.mapcalc allows me to change the elevation value of a point, but how to
change the elevation for the entire cell?
I don't see how to apply r.mapcalc to this.
What raster module will allow me to specify the new value of a DEM cell if
I provide the easting and northing coordinates?
