Hello,
I’m a new user and not sure that I do everything correctly. My main purpose is to map the various hiking trails, but in the mean time I also fix the maps wherever I see missing details. Today I added the Har’el shopping center in Mevaseret Tzion and the school adjacent to the mall. Here’s the changeset: http://www.openstreetmap.org/browse/changeset/3845762
In addition to a general review, I have some specific questions regarding my changes:
If a commercial area is adjacent to a residential one, should I glue the points together?
If there is a commercial area, a road and a residential are on the other side of the road, should I extend the residential area so the road is inside and it “touches” the commercial area or the two areas should be each on its side of the road?
If I have a commercial area in the middle of the town, how do I make a “hole” in the area? Or I just put the commercial area over the residential?
No rules here. Do what you feel is most suitable.
I would leave some room aruond the road, and map the areas on each side of it.
Just draw the commercial area inside the residential area.
As a new user, my best advise would be:
If you want to map something for the first time (i.e. you never mapped that feature) - then look at another example, how someone else mapped such a feature, and the tags, and try to mimic their work.
Unfortunately the only viable solutions seem to be residential area fragmentation or multipolygons, which look quite scary to me I think I’ll go for the fragmentation solution.
I wouldn’t use multipolygon. Though it’s the correct solution, it’s an overkill.
Fragmentation isn’t “right” - The residential area is one big area, it’s not fragmented.
For simplicity’s sake, I would draw it inside.
If you think about it, then it makes sense that such a commercial area should be drawn on top of the residential area.
After all, the commercial are is WITHIN the town’s limits, it’s under its jurisdiction.
Unless it’s an industrial zone with its own “townhall”, like Tefen.
Well, I did a small research and here’s what I’ve found:
Landuse tag denotes the “purpose” of the land and not city limits. Each piece of land can have only one purpose. This purpose is usually defined by the laws of the country and doesn’t necessarily mean that the land is actively used for that purpose e.g. it can be planned but not built yet (in Israel מקבילה למושג יעוד קרקעות בתמ"א). Moreover, sometimes one town can be comprised of different parts that are not geographically connected. Mevaseret Tzion, for example lies on both sides of HW1 and has Kastel NP in the middle.
