While trying to map some building construction sites in the South of Market (SoMA) neighborhood in San Francisco (near the office where I work), I was unsure whether to use building=construction or landuse=construction.
The documentation available at: http://wiki.openstreetmap.org/wiki/Tag:landuse%3Dconstruction (see "Original proposal for this tag" link to http://wiki.openstreetmap.org/wiki/Approved_features/Building_site ) http://wiki.openstreetmap.org/wiki/Key:building suggests that landuse=construction should be used for a large construction site in which a region is covered by construction. There is a major such site in the area, the Transbay Terminal construction project, mapped as http://www.openstreetmap.org/browse/way/89383754 and http://www.openstreetmap.org/browse/way/113511443 , which is clearly using landuse=construction correctly. This documentation suggests, on the other hand, that a single building under construction should use building=construction. However, there is substantial existing usage in the neighborhood of landuse=construction for the construction site of a single building, such as many of the small rectangles in http://www.openstreetmap.org/?lat=37.788&lon=-122.39363&zoom=17&layers=M Use of landuse=construction also seems to have the advantage of distinct rendering in the standard OSM Mapnik style and tool support in Potlatch, one or both of which could be the reason for the existing practice in the area. In particular, I added two ways using building=construction: http://www.openstreetmap.org/browse/way/228167970 is an apartment tower under construction. It's currently a structure about 15 stories high, and getting higher every week. http://www.openstreetmap.org/browse/way/227689990 is a square pit in the ground that has construction vehicles digging the hole in which a building is going to be built. Though the wiki seems to suggest to me that building=construction is correct for both of these, it also seems possible that landuse=construction might be preferable, either for both, or perhaps only for the second. This leads me to the questions: * Should these ways be tagged as building=construction or landuse=construction? * If they should be tagged as building=construction, should the standard map style display building=construction differently (perhaps more like landuse=construction)? -David -- 𝄞 L.
