I am having a problem making a viewshed analysis for every pixel on a raster.
To perform the viewshed analysis from every single pixel in a raster I will need:
- A viewshed plugin (which I am willing to use either the one from GRASS or QGIS plugin for visibility analysis
This is what've done
- STEP 1: Get the points layer from the raster
This is my raster:
What I've done was used Raster Pixels to Points tool:
and then I got this layer:
which I think it's was I need for step 2.
STEP 2: Perform Viewshed Analysis for each Point
As I said I would use one of those plugins/tools, but since the one use in GRASS requires to select one pixel at a time, I was trying to used the other one (QGIS plugin for visibility analysis).
So here is the configuration of the tool that I used:
--> From this point on I have problem achieving what I wanted <--
After I run it I have an error associated with the fact that I am not passing some fields ( which I think are also fundamental, observ_hgt and radius) and I don't know either where to put them...
I even tried to add the fields observ_hgt with the value 1.5 and radius 2000 to each pixel (by clicking Toggle Editing > Open Field Calculator) but afterwards I got another error (as can be seen below):
