title: Which maps I can use to track a fleet of vehicles?
body: <p>I have a project to track a fleet vehicles, each with a GPS device on board that sends its coordinates at regular intervals of time, I was going to use google maps for this purpose but I found that for such a thing should have a license which costs quite a bit. And even with Bings is the same speech.</p>
  
  <p>So I come to my question which maps (free) I can use to track a fleet of vehicles? There are other providers of maps to do a similar project?</p>
  
  <p>Thanks for the answers</p>
