Dear all,
not having received any answer, I repeat the request.
I need to speed up the process of obtaining rasters with distances from a
single point (or a single lat-lon coordinate) in it. Manually I use this
procedure:With a georeferenced raster in a UTM projection I use raster
calculator to obtain a raster with all pixels set to zero. Then, with Serval
plug-in, I manually set to 1 the value of the pixel in the wanted position
(either by using a satellite overlay or by using a point vector layer with the
appropriate coordinates). Then I use the proximity function under
Raster>Analisys menu.I want to make this via the Graphical Modeler, in order to
be able to make the process fast and skip the manual introduction with Serval
plug-in. At the very least, I need a mode to put the value 1 in the pixel of
the selected null raster in the position givel by lat-lon coordinates.
Thank you!Best,Fabio Falchi
