text: Normally we'll only explicitly mark it as such if there are signposts: these are often not present in urban areas. This site has a lot of data donated by councils (including Stockport) but it is often unclear if the data is usable directly in OSM. I've found footpath signage in the borough a little confusing (e.g., around Werneth Low). Ultimately as we collect better data a lot of this will have to be resolved by research at public libraries & council offices.
