By filtering the view of the APRS.fi map to red beacons you get a reasonably good graphic view of where thwWestern Cape repeaters are geographically located.  You can then click on each red dot to get more detail about each one.

To filter to just showing the repeaters, click on the filter icon at top right of the view, select symbol, and then scroll down to "Red dot", and then Save. You'll now be able to click this filter view on/off in the filter view.
