Updating CIE masks?

[NiklasSchwind]

As the masks for the original CIE are from when the CIE was first launched we might want to update them in rimeX, as a few maps might be outdated by now e.g.:

• Ukraine
• Subdivisions of Pakistan

It could make sense to get them directly from the recent Natural Earth shapefile so that this can be easily switched in the future.

Hi @NiklasSchwind, that makes sense to link the masks to a clear shapefile provider such as Natural Earth or possibly GADM. It might take a few days though. Perhaps we should have call soonish to define priorities. (however I don't know what you have in mind about Ukraine, but I doubt CA wants to keep track of de-facto, war-related moving boundaries)

My guess is that it would take two-three days if no major hurdles shows:

• First there is the work on vector data: I remember some countries need special treatment, like France has all these oversea territories that are merged together in NE and might need to be split. Then we might need to check if all islands are present. There there are groups of islands, larger grouping of countries (economic or political alliances) that are present in the CIE, and that would need to be made
• Making the raster is easier (I have existing code I could repurpose), but with processing and checking I would not count less than one day for this.

After that all the reprocessing.
