Creating a LocationDataSource from Symbol Geometry/Attributes

rod182211 — Thu, 06 Jul 2023 04:45:39 GMT

Hi, I have developed an application which takes in feeds and places military symbology IAW the esri MIL-STD 2525D stylx on the map based on the feeds(Video concept below).

What I want enable is a Geotrigger based on when one or any of the Symbols on the map enter my definded fence parameters. I have no issue in achieving this utilising a NMEA feed as the LocationDataSource for my local node.

Unfortunately I don't know how to impliement a method to GeotriggerFeed locationFeed = "need away to get a alternate LocationDataSource from Symbology information"

I am hoping someone understands my question and can provide advice on a possible solution.

@rod182211 we have a sample app which shows how to implement geo triggers.

There is also some documentation explaining the subject.

Does this help?

Thanks for the reply. I have no issue with the methodology shown within the example. I already do that for my local node. This method uses the LocationDataSource provided by the NMEA feed. (All good) My application however connects multiple nodes communicating with each other. Each nodes location is transmitted across the network and an associated miltary symbol is shown on each node's map and updated as they move providing a picture of where every node is within a given location and time.

My question is, say I am at node A and I want to set a geotrigger on when Node B and or C enter a fence created my map only. The only reference I have is the symbol I have created on the map and its associated attributes. How can I leverage this information to feed the geotrigger. From what I can tell the only capability currently is via LocationDataSource provided by a local NMEA source.

@rod182211 I'm going to seek out someone on the geo-trigger team to assist with this.

Thanks heaps. I am also hoping to be able to achieve the same concept for location history.
