-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I am aware of the problems with using residential areas for village outlines, however using the place=* instead of landuse=residential on the outline doesn't really solve the problem either. Many African towns are composed of numerous clusters of buildings. For these we map each as a separate area, which gives a much better picture of the layout of the town. But it would not make sense to do a separate place=* for each of these.
A good example of this is Gueckedou. For this town we have actually gotten neighborhood polygons from MSF. Notice that they _almost_ match up with the residential areas we have mapped now, but not always exactly. Even some neighborhoods have many residential areas mapped. http://www.openstreetmap.org/#map=15/8.5607/-10.1297 What we really need is a new landuse type for 'built up area' or something like 'populated place'. This accurately describes what we are tracing, without implying that we know it is actually residential (and not commercial or industrial or something). I don't know what to use for such a thing and it would need discussion as well. Does this sound like something that would make sense to take to the tagging mailing list? Should a proposal on the wiki be started? And most importantly, is there someone who wants to lead the effort to get such a tag worked out? Keep in mind that since other orgs that don't understand tags and rendering issues are using our maps currently and making use of the residential polygons; so any changes to the tagging need to get reflected in the OSM carto and also the HOT HDM rendering as well. They cannot just all dissappear. - -AndrewBuck On 08/14/2014 05:32 PM, Paul Norman wrote: > > On 8/14/2014 3:12 PM, Pierre Béland wrote: >> As a general rule, we outline residential landuse areas using the >> tag landuse=residential.
