I’m not sure about the process, but I noticed that Örebo Kommun has open (CC-0, so it should be allowed as far as I can tell) data available:
As a test I successfully added the WMS endpoint into JOSM. (what you need to use is http://karta2.orebro.se/mycartaserver/opendata.wms).
However, before I use this data source and also before I try to add it to add this to https://josm.openstreetmap.de/wiki/Maps/Sweden I would like some guidance:
- Make sure that I understand the license compatibility correctly.
- Technical guidance on the process of adding the data source. There are complications such as listing supported map projections for WMS source. How do I figure that out?
- Also, there are several layers available. Several seem of interest to OpenStreetMap such as “vägtrafiknät” (lines indicating car roads), “lekplatser” (playgrounds) and “parkytor” (park areas). However, some, such as solar panel installation data and noise measurements do not seem to be of any interest to OpenStreetMap. Should a wms_endpoint be added so the user can select which layers to use, or should each of the layers of interest be added separately?
- There are also several vector layers available (see http://data.karta.orebro.se/). There is some overlap between WMS layers and vector layers, but neither is a superset of the other. Can we even use these vector layers with JOSM?
