[OSM-talk] Monitoring activities : visual tools for data mining into history of objects

[Pierre Béland]

Various Activity Monitoring tools such as Whodidtit provide the list of recent changesets in an area. But nothing to visualize on the map. The only solution I know to visualize is to revert a Changeset in JOSM. This way, it reconstruct and show the objects of the Changeset.


To efficiently monitor the mapping of an area, it would be more powerfull if it was possible to compare on the map the Changeset objects or a particular object (ie. Bbefore and After states). 


Some History comparison tools show the history in a table where you can select two versions of the history.  This could be adapted to show the objects on two contiguous maps or two layers.

Deleted objects are particularly neglected. If it was possible to visualize rapidly what the object looked like before erasing it, this would greatly facililtate the monitoring of an area.

As a monitoring tool, the comparison of two maps would effectively complete History comparison tables that already exist.
