Hi: I need help rendering this water park. http://www.openstreetmap.org/edit?editor=id&lat=38.754401&lon=-77.440391&zoom=18 There are four ways. The inside is a swimming pool (way #1), then the paved area (way #2) then the ‘river bank’ (way #3) and finally the boundary of the paved area around (way #4). I know how to render two polygons, for example a lake surrounded by a wooded area. The lake = the inner polygon will get normal tags and the outer way (wooded area) gets its tags in ‘Relations.’ I also read item #7 at http://wiki.openstreetmap.org/wiki/Relation:multipolygon How should I apply this? My first ‘set’ of polygons would be #1 ‘inner’ and #2 ‘outer’? Then another set of polygons, that is #3 as ‘inner’ and #4 as ‘outer’ Or only one polygon as ‘inner’ (#1) and the remaining three as ‘outer’? Thank you. |

After many attempts I think I made it work. Step 1: Using Potlatch, I created the first pair of polygons, #1 (inner) and #2 (outer). I tagged the inner as 'swimming_pool' and outer in Relations as pedestrian paved area. Step 2. I created another pair of polygons, #2 (inner) and #3 (outer). I tagged the inner as pedestrian paved area and outer in Relations as 'swimming_pool'. Step 3. I created another pair of polygons, #3 (inner) and #4 (outer). I tagged the inner as 'swimming_pool' and outer as pedestrian paved area. The reason I believe it worked is that the swimming pool and the 'river' ring are rendered in blue and the paved area in light gray color. If you need more details feel free to contact me. Martin |
