Re: [Qgis-user] raster with distance values from a point

Hi Nicholas: If you activate the various providers under the Processing toolbox options, you can have direct access to the various algorithms I mentioned.  I often generate a quick general model, export as a python script and then refine the script as required. I am running 3.16.2-Hannover.

Interesting Kirk, The QGIS vector to raster conversion is not available in the graphical modeler or do you have another reason behind your solution? I don’t use much the graphical modeler so I appreciate your incite. Cheers! Nicolas Cadieux https://gitlab.com/njacadieux > Le 25 févr. 2021 à 1

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 t

To add to Nicolas" comment: 1) Create your point layer from a csv (easting, northing id) as a minimum 2) If you want to stay with process modeler, use the SAGA>Raster creation tools> Rasterize Algorithm to convert the point layer to your required resolution and size 3) Use the  GDAL>Raster A

Hi, You can cut down you use of several plugins by doing the following, 1) Create a vector point file with a single point having the numerical field containing the value 1.  This file could be a csv containing WKT. 2) Use the vector to raster conversion.  (This will take your vector point fi
