[Imports] Slovenia - Landuse import questions

[Jaak Laineste (Nutiteq)]

Hello,

I have general suggestion: do not try to bring all the original complexity of the data to OSM. OSM needs to remain maintainable by the crowd, but these details can be observed and verified by domain experts only. So use wood, forest etc - keep it as simple as possible. Otherwise you will make later maintenance much harder to your fellow editors. Many would be fooled by details - see that “this is so detailed, I cannot edit it, I do not know the details”, even after some years when the data is obviously outdated.

If someone really needs high attribute details of your original data, then they can and should go to the original source anyway. They would need to do it anyway to get the latest updates.

Do not map for (the sake of most detailed) map, map for the community.

Jaak

We did this in NZ and you can see an example here - http://linz2osm.openstreetmap.org.nz/data_dict/layer/boatramp_cl/info/. Do not tag for the renderer - Others may well create their own maps which do render the content. I wouldn’t 'dumb down’ any tags either. Orchards already have a deep tagging scheme which allows you to specify the crops that are planted - http://wiki.osm.org/wiki/Tag:landuse%3Dorchard.
