I wasn't able to check completely local with npm run test, sorry

thanks @okilimu , it looks pretty good 👍
I see a few warnings that some of the geojsons cover a very small area - in these situations the geojson is kind of wasteful, so we usually just specify a point.

Points as [longitude, latitude] coordinate pairs. A 25km radius circle will be computed around the point.
Example: [8.67039, 49.41882]

I'll convert them and merge, if that's ok?

[okilimu]

you can use a point instead, thats ok.
Should i define the point and sent a new pull request or do you make the changes for yourself?

I'll just make the change - just wanted to ask first!
