area-to-point Kriging for spatial non-temporal data #130

Closed nikosGeography closed 9 months ago

nikosGeography commented 9 months ago

Hi, I'm relatively new to geostatistics so I apologize in advance for my question. I was wondering if the package offers the option for area-to-point Kriging (ATPK) for non-temporal data. From the documentation I saw that for spatio-temporal data there is the function vgmAreaST. For spatial non-temporal data, the vgmArea computes point-point, point-area or area-area variogram values from point model, meaning there is no area-to-point function?

I am aware of the atakrig package where I can perform ATPK but I was wondering if gstat has that option as well.

Thank you.

Not really; there's a demo script that does something here, but it doesn't do for instance point variogram estimation from area data.

Thank you for your prompt response. Is ATPK something that you would like to implement in the near future? I mean for non-temporal data.

It would be nice to have, and possibly low hanging fruit, but for me personally a low priority.

I see... Should I close the issue or leave it open in case someone is interested to implement it?
