APRS integration demo

Is there a demo anywhere showing APRS radio integration with SAR Topo, both online and offline? I would really like to see a screen recording showing radio tracking in the field and describing all the features that are available, e.g. whether I'm limited to the radio's most recent location, or if I can show a line string of its movements.

What little knowledge I do have comes from various snippets of information on configuring the system, e.g. https://help.caltopo.com/kb/objects/aprs-objects, but nothing shows me what the system is capable of. I found https://sartopo.com/m/JHJA, which appears to show radio locations, but with no explanation I'm not exactly sure what I'm looking at. The YouTube SAR Topo tutorials at https://www.youtube.com/playlist?list=PLnxLnArgHCjbuZiQNWDMm26xWcrSUZ-2M don't seem to cover APRS.

    Unless a SAR team has created a demo we at CalTopo have not done anything like that. We track points as locators update their location, so if your radio transmits a location (and that is received) that is then plotted and added to CalTopo. It's more dependent on the radio or tracking device, CalTopo just feeds that data onto the map and into objects.

    We have a couple folks that are pretty practiced with this so feel free to send specific questions. King County SAR in Washington State and Matt Cosand who works for CalTopo have done a lot with APRS.

    We just added a configuration KB article that we will continue to refine over time. This isn't a super popular method of tracking, but has clear benefits so we'll work to update the documentation more over the next few months.
