What is the frequency at which Tracker collects a user's location? Is it based on the Field Maps Collection Settings > Streaming, or is it a set interval based on either distance traveled or time?
Wanting to report on average speeds and time spent on activities (walking, driving, stationary) in a dashboard, but need some reference to how often the points are obtained for those calculations.
This is covered in depth in this FAQ. Basically, points are collected based on distance and activity in order to avoid capturing unnecessary points and to improve battery life. There is no strict temporal frequency.
Thanks. Wasn't sure if the frequency of point collection could be modified any or not.
So, doesn't look like I'll be able to do what I was hoping to... report (on a dashboard indicator widget) report the total amount of time spent performing walking, driving, stationary activities.
Yeah I don't think you'd be able to do this on-the-fly. You'd have to post process the data to find times when someone was moving and when they were dwelling. There are tools in GeoAnalytics Server that can detect dwell locations when called from Pro or Map Viewer.
Check me on this...
If walking points are collected every 5 meters, and speed is reported in meters per second:
Is that right?
Won't be 100% accurate, since I'm using average speed, but hopefully will be close enough for rough estimates.
Only thing I won't be able to report on is time spent being stationary (standing still performing an inspection on a meter), since there is no speed and nothing in the FAQ that specifies how often points are collected when stationary.
