You have to distinguish between mapping features for which our database is suitable and which are geodata and on the other hand metadata, raster data and encrypted data (like unique IDs of nondisclosed external databases). Coverage of a proprietary imagery provider IMHO isn't really suitable to be mapped in OSM, but could be tolerated for practical reasons. > I personally thing that mapping of underground power lines doe snot belong > into OSM.

I thought the only question we're still discussing is how to deal with outdated outlines (better keep/ignore them when outdated so maybe someone can update them, or simply delete them). cheers, Martin
