A system for asset tracking and monitoring including a data server coupled to a wireless network and global information network, a mapping database, a user interface, a plurality of wireless GPS devices having varying data formats. Each wireless GPS device (e.g., GPS/cellular phone, GPS/pager device) is registered in the system (i.e., identified by a unique address or the like). Users log into the system and request the location of the registered device via the global information network (e.g., Internet World wide Web interface). The data server receives GPS position information from the various GPS devices regarding the location of each device. This information can be explicitly polled (i.e., requested) by the data server or automatically sent, by the registered device, to the data server on a scheduled basis. A data converter processes the GPS position information into a common format. The data server then generates a map identified with the location of the device in question. The map is displayed to the user via the Internet (World Wide Web) interface.
