It currently shows the path of a single packet, when you point an APRS station or a track point with the mouse cursor. In the screen shot on the right I had the mouse cursor pointing to the oldest waypoint of OH7FDN, and that position packet was relayed by the digipeater OH7RAA, and forwarded to the APRS-IS by the igate OH7AA.
There are a couple of limitations in this implementation:
- It currently only shows the first digipeater found in the path, and the igate.
- The digipeater and the igate must be visible on the map (or just outside the visible map area) - you might have to zoom out to make them visible.
- The digipeater and the igate must be visible on the map - if you're tracking a single station (you've just searched for a callsign), you'll have to click on "stop tracking".
- It currently only works in the real-time view - it doesn't work if you select a day in the past (because it only shows a single station in that mode).
Features like this always come with a performance penalty. To provide the additional eye candy I'll have to pass on more data to the web browser. It will consume a bit more memory, and make the web browser slow down some more. I certainly hope it's worth it.
