The OsmApi module contains changeset functions that are usefull to interrogate the OSM API and obtain the history of objects.<br><br>For a BBOX, a specific contributor and a date range, we can interrogate the OSM API an list the changesets. Below are examples for changeset ID=16327554. <br><br>And looking
more in detail about the Changeset function, I see that there are collection of objects edited. We should be able with this historical data to calculate more detailed statistics (ie. objects created, modified, deleted).<br><br>It is quitee easy to treat this with Python script but there might be some limits when interrogating the OSM API. Then, it is possible to shorten the period analyzed.</span><span style="color:black;"></span></div></div></div></div></div></div></div></div></div></div><br><br></div> </div> </div> </blockquote></div> </div></body></html>
