I am trying to track the location of my devices and input them on a map, also what’s the best way to save the location data to analyze and get insights from!

You can store the lat and lon on the device and then send an event when the values change or update Particle variables. Remember to convert the float to double to include as a Particle variable. You could set up a webhook to post the location to a google sheet or some other service that can receive and plot on a map the lat and lon.
