Node-red-contrib-cot2xtopo NPM

node-red-contrib-cot2xtopo

Parses CoT message from a stream, parses for PLI messages for coordinates and callsign, and then sends a location to CalTopo using the API and connect key generated by team accounts

SUMMARY

This Node RED subflow listens in on a network kml file such as the one produced by a CalTopo Team account map, parses out the position location information (PLI) of personnel and streams the cursor on target message to a TAK Server or multicasts to via UDP on a virtual private network.

Pre-Requisites

Node RED installed and continuously running (See Greg Albrecht's video on how to install Node-Red on Windows)
CalTopo Team account with a Map ID and the map's Base Permission set to URL
node-red-contrib-tak node

If using a TAK Server (Optional)

An open port on your TAK Server using an x509 authorization if you plan to use tls (most secure)
A certificates generated by the TAK Server and the TCP node (See Greg Albrect's video)

LIMITATIONS

If your team creates new maps for every call, you will need to manually inject the new Map_ID using the Inject node in Node RED or create a User Interface Text node. Your other option is to dedicate a specific CalTopo map for live-tracking or SMS Locators.

The function node has some filtering to assign a color for a terms found in the callsign. Edit those, needed.

CONTACT INFORMATION

If using an SMS Locator in CalTopo and if you provide a callsign titled subjectdigit (e.g. subject1 1118675309), the telephone number will be parsed and available in the TAK's Contact menu in ATAK / iTAK to allow you to call or text the subject by tapping the PLI in ATAK / iTAK. Using subject in the name will give the PLI a Magenta color / team.

NOTEUse this with caution, as if the subject is not actively updating their browser, their position will stale out due to mobile os security settings. SMS Locators should be treated as Last Known Positions.

REQUIRED NODES

INJECT: The msg.payload should be set to the CalTopo Map ID, which would be the last 5 characters of your CalTopo URL. For example, if your map url is https://sartopo.com/m/ABC12, the map id would be ABC12.
node-red-contrib-tak: This node is required to pass the CoT message from this subflow to a TAK Server or EUDs on a network.
TCP OUT:
- TAK Server: If using TLS, check on the SSL / TLS option and create or edit your TLS Configuration, as needed.
- UDP: This would need to be configured to your vpn settings and requires your Node Red instance to be on the same vpn to multicast to TAK end-user-devices.
