[OSM-talk] Community Edit Monitoring vs Worldwide BOT Coverage in Changesets

[Pierre Béland]

Thanks Pavel

The changesets listed were reduced by half when providing the url http://www.openstreetmap.org/browse/changesets?bbox=-73.6318%2C45.409%2C-73.444%2C45.4946 with http://positron96.appspot.com/osmfilter.html.

This solution would effectively eliminate an important amount of changesets from the History Report if it was adopted.


Therefore, this solution does not cover all the situations. When a worldwide changeset covers partly a local area, it is quite uneasy to detect wich objects were modified in this local area. Especially when the changeset  affects hundreds of objects. 

If changesets were limited to one country (or nearby countries when crossing borders), there would be even less changesets reported in a local area. Changesets would also contain less objects. 

Both revising the History Report and establishing rule to restrict the coverage area of changesets would facilitate monitoring in a local area.

There are some works in this direction, the most recent seems to be http://zverik.osm.rambler.ru/whodidit/ . There was OWL which is now down, but is promised to be back.

shows all the changesets covering a local area. In this display, we often see Worldwide 
BOT Changesets even if there is no modifications made to the area,. RSS feeds are producing false alerts, and it is uneasy to find if any changes are made to the local area. We sometimes have to go to hundreds of modifications in the Changeset to verify if the local area is affected.
