This application helps you find which nodes have not been edited for a long time, by using on Ohsome API and various softwares and libraries, such as Leaflet, React, Python, Redis and others. It is the result of a thesis project.

Demo: is-osm-uptodate.frafra.eu

Page on OSM wiki: wiki.openstreetmap.org/wiki/Is_OSM_up-to-date

Open is-osm-uptodate.frafra.eu (or your local instance). Move, zoom or find and select a new location in order to get the nodes for the new bounding box.

QGIS supports XYZ/TMS layers natively. Create a new XYZ Tiles connection using these parameters:

• https://is-osm-uptodate.frafra.eu/tiles/{z}/{x}/{y}.png?upscale=256
• min_zoom_level: 12
• max_zoom_level: 17 (recomended)

The tiles URL can be also configured with additional parameters, such as:

• resolution: each tile has resolution x resolution pixels (deafult: 8)
• filter
• mode, which can be set to:
  • creation
  • lastedit (default)
  • revisions
  • frequency
• scale_min
• scale_max

Here is another example:

https://is-osm-uptodate.frafra.eu/tiles/{z}/{x}/{y}.png?upscale=256&filter=amenity=*&mode=revisions&scale_max=10

Example:

$ curl 'https://is-osm-uptodate.frafra.eu/api/getData?minx=9.188295196&miny=45.4635324507&maxx=9.1926242813&maxy=45.4649771956' -o milan-duomo.json
$ curl -X POST -F geojson=@boundary.geojson 'https://is-osm-uptodate.frafra.eu/api/getStats' -o stats.json

Try a smaller region or wait for a while. Be sure to have a stable connection.
