To-fix: Double places

[Yurasi]

Currently, there are many duplicated places in OpenStreetMap,which is not really good, and generates confusion some cases which we found are::point_down:

• Case 1: Two points with the same tags name:* and place:*

Node 1,Node 2

• Case 2: A point and a polygon, with the same tags name:* and place:*

Node, Way.

Objective

Cleaning up doubled places in OpenstreetMap.

Tasks

We have a to-fix task, that contains the doubled places issues

https://osmlab.github.io/to-fix/#/stats/doubleplaces

Changeset comment

Fix double places:* and with the same name

Tools

• If using iD editor, work with To-Fix web.
• If using JOSM, work with Josm-tofix-plugin.
• Use Replace Geometry (Shortcut: E).
• Add inverse filter: place.

# Instructions to fix - When two place nodes exist, combine the tags into one, and set the place in the center of these nodes. - When a landuse and a place node exist, combine the tags into one, replace geometry. - When a boundary and a place node exist, create a relation `type=boundary` where the polygon will be the `outer` role and the node place will be the `admin_centre` or `label` role. - When a landuse, boundary and node exist, combine the tags from landuse to boundary, except `landuse tag`, after delete the landuse. Check or add the place node into relation with `admin_centre` or `label` role. > - `admin_centre` - The node that is considered to be the administrative centre (usually the node tagged with place=city/town/village) > - `label` - The node that is considered to be a hamlet, village or neighbourhood. **More info:** - http://wiki.openstreetmap.org/wiki/Relation:boundary - http://wiki.openstreetmap.org/wiki/Tag:boundary%3Dadministrative - http://wiki.openstreetmap.org/wiki/Tag:boundary%3Dadministrative#admin_level - http://wiki.openstreetmap.org/wiki/Key:place - http://wiki.openstreetmap.org/wiki/Talk:Relation:boundary - https://wiki.openstreetmap.org/wiki/Relation:boundary#Relation_members ### Common issues ### Case 1:  _Select the two place points at the same time, after press the `E` key (Replace Geometry)._ ### Case 2:  _Select the place point and the landuse at the same time, after press the `E` key (Replace Geometry)._ ### Case 3  _Select the boundary and node at the same time, then add these in a relation of `type=boundary`. Also add the place node into the relation with the rol `admin_centre`._ ### Case 4  _Select the landuse and copy the tags that lack into the boundary, after delete that landuse. Add the place node into the relation with the rol `admin_centre`._ # How are we doing the error detection? We are using [osm-qa-tiles](https://osmlab.github.io/osm-qa-tiles/) and osmlint [doublePlaces](https://github.com/osmlab/osmlint/tree/master/validators/doublePlaces) to get a geojson file of these issues and then we uploaded into [to-fix](https://osmlab.github.io/to-fix/#/stats/doubleplaces). # Who will work on these tasks? Anybody on the community who is interesting on cleaning up these issues. ### Question Any questions, please drop a comment to discuss it. cc. @mapbox/team-data

In this case, How does it solve? There are 2 points and a landuse with the same name San Francisco Del Monte Subdivision https://www.openstreetmap.org/way/153303599

In OpenStreetMap, It shows like this https://www.openstreetmap.org/#map=19/14.43091/121.01238

:hand: @ian29 @ajashton @ingalls , could you help us on this issue https://github.com/mapbox/mapping/issues/290#issuecomment-299311120?

1. Due to the fact that node (https://www.openstreetmap.org/node/3929066188) is inside of the "Veraville Homes 1" (https://www.openstreetmap.org/relation/3291321) I I would delete this node.
2. The node https://www.openstreetmap.org/node/255059566 is good to merge with https://www.openstreetmap.org/relation/3291321 as they are the same.
3. The node https://www.openstreetmap.org/node/255064224 is good to merge with https://www.openstreetmap.org/way/153303599 as they are the same too
