I have been reading about interpolation and am trying to understand whether interpolation results in a vector or raster. Say I have a layer of points and I am interested in creating a raster that fits a known grid (aligns with another raster). Do I interpolate and then convert to the raster or is raster conversion a part of the interpolation process?
I have point vector data and a raster, so I am trying to convert my point data to a raster. From what I have read interpolation is a reasonable thing to do when converting points to a raster.
My data is stored in a PostgreSQL database, so I am trying to use Python and QGIS. I am pretty familiar with Python but not so much with this type of processing since most of the data I work with is typically tabular.
