I am investigating the effect of point spread function (PSF) during spatial downscaling. The process of spatial downscaling involves two steps:
- regression (GWR in my case)
- area-to-point Kriging (ATPK).
In order to investigate the effect of the PSF I have to take it into account in both steps. My question is this:
Is there any package in
R that takes into account the PSF during geographically weighted regression analysis?
I am asking this because during ATPK, I insert the values of the PSF into the function (I am using the
atakrig package). For example, in the
atakrig package I insert:
pan.d = discretizeRaster(pan, 100, type = "value", sigma = 0.2, psf = "gau")
