Usage of the service is quite simple. Just follow these steps:
- Copy the URL of hisotry page on OpenStreetMaps site
When you want to track changes on a certain area, you usually go to history tab to look at changesets list. Go there now:
You need to copy URL of the history page to clipboard. This can usually be done by clicking somewhere in the address tab and pressing Ctrl+C or selecting "Copy" from context menu.
- Paste it into the textbox above
- Tweak filtering options, or leave them as they are
You can also tweak filtering threshold for your needs. At the moment you can modify filtering area size. By default, the feed will contain changesets smaller than 20 degrees latitude and 40 degrees longitude. You can change that via "Latitude limit" and "Longitude limit" textboxes. Input float or integer numbers there, like this:
- Click "Get filtered RSS URL" button
- Use that URL as you prefer
That's it! The link leads to a feed that contains the very same data as the original feed except that it drops large changesets.
You can just click the link if you want to use an aggregator built into your browser (like Internet Explorer, Firefox, Opera) or copy and paste it into your favorite RSS aggregator or on-line feed readers like Google Reader.
