Recommended Workflow for Desktop/Offline Use

Hey all,

Our county SAR team is in the process of developing a standard workflow for SARTopo. We have a Team account and online use has worked out great so far. But we've been having some back and forth on what is the best way to set things up for a search when we are out of cell service and working offline. We've proposed the following workflow and wanted to run it by the SARTopo developers and SAR community to see what folks have found works best:

- Run a local area network (LAN) in the command unit and have SARTopo desktop (with maps downloaded beforehand) running.
- To share a map with searchers (both on and off our Team account) running the SARTopo app, have folks connect with the wifi on their phone to the LAN.
- From here they should be able to download the map for field use.
- As they work in the field with the map, their phones will log their data (tracks, waypoints, etc) locally. Once they return to the command unit, they reconnect to the LAN and their data will be uploaded automatically to the base map.

Is this the right idea? Any recommendations on either the workflow or necessary hardware?

Cheers,
Tony

    Sort of.

    A single SARTopo Desktop install with multiple browsers accessing it over a LAN is definitely the recommended approach.

    You can publish a GPX or GeoJSON file that people can load onto their phones, and they can offload tracks at the end of the day, but the app does not automatically sync to SARTopo Desktop, only to sartopo.com. There are a lot of security issues with doing that, we're still a long ways off from being able to support automatic app-desktop sync. As a side note, in my experience it can also be difficult to get everyone's phones connected to a .local server name over wifi - I'd expect a bumpy road there, but maybe you'll have better luck.

    You should not need any special hardware, even when serving multiple users over a LAN, SARTopo Desktop is pretty light.
