I have previously used OsmCha to keep an eye on changesets affecting an area of interest using their polygon / country search tool. Recently this type of filter appears to be failing, and the RSS feeds don’t update. The Bounding Box queries seem to succeed but in my case one corner of that box goes into an area that is way more active than I can cope with long term. Most other QA tools seem to be bounding box based.
My questions are:
Are there any other online monitoring tools for generating an RSS feed for an arbitrary polygon that are currently functioning?
Failing that, are there any tools out there for experimenting with multiple bounding boxes on a map so I can play around with some options to chop off a corner by using multiple BBox feeds?
