Having your own Web-based mobile Global Positioning System (GPS)
tracking system doesn't have to be a complicated and expensive ordeal.
Now you can build your own simple mobile GPS tracking system from a
laptop and have the data delivered right to your own computer. With
the addition of a Web server--and a Google Maps client-side
JavaScript--you'll be able to see the data via the Web on an
interactive map.
