Source Types
If you have a lot of content, your feed could become very big in size. In this case, you can also tell us to retrieve feed content not all at once but region by region.
The available source types are described below.
Bounding box
We will request feed content from your server for particular regions. These regions are specified by bounding boxes, consisting of two latitude/longitude coordinates (four values). Just include the following placeholders in your URL:
${WEST}, ${SOUTH}, ${EAST}, ${NORTH}
For example:
http://myserver.com/myFeedServlet?BBOX=${WEST},${SOUTH},${EAST},${NORTH}
We will then request feed content from your server for particular regions specified by latitude/longitude coordinates, e.g.
http://myserver.com/myFeedServlet?BBOX=11.513730727858094,48.19257657657658,11.569085202511259,48.22947747747748
As return value, we expect the complete content for this region.
Center radius
We will request feed content from your server for particular regions. These regions are specified by circle consisting of one center coordinate (latitude/longitude) and a radius (in kilometer). Just include the following placeholders in your URL:
${LAT}, ${LON}, ${RADIUS_KM}
For example:
http://myserver.com/myFeedServlet?CENTER=${LAT},${LON}&RADIUS=${RADIUS_KM}
We will then request feed content from your server for particular regions specified by latitude/longitude coordinates, e.g.
http://myserver.com/myFeedServlet?CENTER=11.513730727858094,48.19257657657658&RADIUS=10
As return value, we expect the complete content for this region.
The URL and the reload interval will be set when you create a channel (step 3).
