What are the rules based on which resource locations are decided?

When a resource is in the field, the application sends the GPS coordinates of the resource to the routing engine, if they're available. This helps Routing decide the location of the resource.

These rules are used:

Activity Status	Scenario	Coordinates Sent
Route isn't yet started or no activity is started on the route	The resource’s GPS coordinates are obtained between 0–20 minutes.	The GPS coordinates are used.
	No GPS coordinates are available, or GPS coordinates are greater than 20 minutes.	The resource's Start Location is used if it's available.
	No GPS coordinates are available, or GPS coordinates are greater than 20 minutes, and no Start Location is assigned to the resource.	The resource's location remains undefined.
Route has a started or a completed activity	The resource's GPS coordinates are newer than the address of the started or completed activity and the resource is at a distance more than 20 minutes from the address of the started or completed activity (using airline distance and default company airline distance speed).	The GPS coordinates are used.
	No GPS coordinates are available, or GPS coordinates are older than the address of the started or completed activity, or the resource is at a distance less than 20 minutes from the address of the started or completed activity (using airline distance and default company airline distance speed).	The address of the started or completed activity is used.
SLR is enabled and resource completes a non-travel activity or an activity that doesn’t include address coordinates	Resource proceeds for the next activity that involves travel.	The current GPS location of the resource after the route is activated is used as the starting point of travel.
