receiving, by a server computer, said positional data of said locator device, said positional data including at least latitude and longitude information calculated by said locator device;
storing said positional information a tracking table associated with said server computer;
receiving, by said server computer, a request from a subscriber for positional information of said locator device;
validating, by said server computer, the identity of a subscriber user;
if said validation is successful, then retrieving subscriber information from a subscriber table associated with said server computer;
retrieving said positional information from said tracking table;
convolving said positional data with a map overlay without any further computation necessary to determine the location of said locator device, thereby producing a subscriber image having the positional data superimposed on a map image; and
transmitting said subscriber image to a subscriber computer over the Internet in accordance with information stored in said subscriber table.
