Easily map individual parking spaces using the terracer plugin in JOSM
Diposkan oleh PlaneMad pada 7 Mac 2016 dalam EnglishMade this gif around a year ago for someone asked me how to trace parking spaces. After trying different methods and plugins, I found this to be the simplest workflow:
Is there a quicker way? please share.

You can save the second line by using the extrude mode (X), then alt-dragging the first line down.

Hello PlaneMad, when I have finished ALL tasks in the tools listed on osm.wiki/Quality_assurance for my local area, I will consider to start some micro mapping of parking lots … not earlier … :-)

Would have to adapt the Terracer plugin to make it quicker (to remove need to remove building tag and add amenity tag). Good animation as always :-)

Amazing!

This is awesome @PlaneMad.

not dismissing your work, but I think my way is easier and a lot more in line with the norm
Map the whole parking area as amenity=parking
Thats it. 1 polygon/closed way
If I know the info, I will add capacity, operator etc
I’m not sure I see any benefit in mapping spaces to this level of detail (and I’m a lover of micromapping)
One major downside is the visual clutter it would create due to the amount of Parking icons appearing on the map

@DaCor, there would be no visual clutter because the tag is amenity=parking_space, not amenity=parking.

oops, meant to comment here instead of at the source so pasting here too… A plugin called gridify can help make slightly shorter work of that; draw a box (I use building tool), check/change tags, use gridify to split in # of rows ‘and’ columns. I then select the spaces and the general parking area and add both (should I just do spaces only?) to a relation of type=site and site=parking. Seems to work nicely on the slanted parking slots too though you need to start from a paralellogram even if you sloppily make a box and add a couple nodes then delete the excess from the corners or grab 2 of the nodes on one side and slide them to get your slant.

I use building tool: 1 time setup: go to Data>Set Building size>Advanced>[Set all relavent parking tags there I want by default]

Though you can do that, if spaces are evenly divided, the example above requires drawing 12 less lines and does not require all the split operations as gridify does all that work for you. When I do longer or curved parking and notice distortions then I will manually break it up into smaller chunks (=occasional use of step 4+6 but on groups of spaces) then apply gridify to each chunk. This also works with angled spots where cars enter only in one direction. I also sometimes ignore the current ‘paint’ and divide the area as its likely intended figuring after a while it all gets repainted/paved and the next try will likely be better; areas for that are usually bordered by curbs. If it seems less bounded then I may copy the paint as is now. To deal with the missing spaces on the ends I usually map as if they were there so other spaces line up right and delete the fakes after to get more consistent dimensions on the spaces. Adding the single end spaces later would also work but seems like more work to add a 4+ node area after then to delete an area. I will usually add lines/nodes temporarily if helps with alignment then delete when done if they weren’t a further part of the object. One example area I worked on (and need to do a lot more) with angled spaces is osm.org/#map=19/33.64353/-112.22515 but I can find others again if desired.
