Re: GC138H3

It is not my cache, but an old cache I am potentially interested in to log it. But I have no idea if I am qualified and without a checker it is quite difficult to check. I am curious if it is possible to make a checker for this challenge. It is about former municipalities in the Oslo Region, Norway. Nowadays and in Project-gc Oslo is 1 municipality, but apparently this wasn't always the case. According to the listing, the municipality borders are defined by the map Mapsource kart N250 Norge.

It will take a lot of time & energy for us to build polygons. This may or may not happen, and if it does, it may not be for a while.

@Hügh

I'm not sure if it helps because the borders would need to be double checked with the CO, but these borders at least exists in osm-boundaries.com and can be downloaded as GeoJSON directly there.

Norway -> Oslo -> Oslo -> Admin level 9 but exclude "Marka" and "Sentrum" and you have the same areas as mentioned in the cache description. (I used the latest completed OSM DB: 2023-06-05)

Oh good to know. I will look into building polygons from that.

A word of caution because the old boundaries have changed in OSM DB: 2023-06-05.

You need to use an old OSM DB were "Sentrum" does not exit. I was trying to look for this but had no luck for this yet

@Vogelbird

Based on the wording of the cache page I'm not sure this is actually the issue you think it is, but it would of course need to be confirmed with the CO.

To clairify, the "Sentrum" has looked like that since at least 2004 according to the official sources I can find so a OSM-DB without it doesn't sound likely and based on the wording on the cache page I believe the area should be a blank spot were the caches in the area are just not relevant for the challenge.

OK that make sence just the 15 mentions on the listing

That's fine. No hurry
