(Click here for larger image of PLT screenshot)Once users create "buddy groups," they can track their buddies' locations, and let others in the group see theirs. Perdiemco says that PLT has the ability to create zones, either rectangles or irregular polygons, and notify the user via email or SMS when other group members enter or leave the zone. In addition to tracking locations on a handheld, locations can also be tracked on a network-connected PC.
Users have a number of options in controlling how and when location information can be viewed, according to Perdiemco. Data sent to the company's map server is tagged with a PIN password, and only those with the PIN can view the data. PINs can be changed at any time to make location data unavailable, or the data can simply be deleted from the server -- all of which can be accomplished from a handheld device.
The PLT software and service is free for personal use. It requires a Windows Mobile device with GPS and a wireless data connection.
Perdiemco says it has applied for patents covering the GPS location and zone management software technology built into PLT.
