I'm trying to use the proximity tool to create a distance raster from a single vector point. I found here: Calculating distance to points in QGIS and [d-3] Create Proximity Raster. However, I couldn't go past the first step which is rasterizing the vector point layer.
I couldn't figure out how to rasterize the single point and extend the raster to a specified distance, like a buffer, and set all the other values to nan or zero. I've tried the different rasterizing tools available in QGIS but I couldn't find anything that works.
