A data acquisition device, comprising: a global positioning system, GPS, sensor configured to determine a GPS position comprising a latitude, a longitude, and an altitude, and a processor configured to: receive via the data acquisition device, from a host system, National Electrical Manufacturers Association, NEMA, formatted data for a destination address, the NEMA formatted data comprising a latitude, a longitude and an altitude associated with the destination address; receive, via the data acquisition device, an indication from a user of the data acquisition device that a delivery to the destination address is about to be made; determine, via the GPS sensor, a current GPS position of a location; compare said current GPS position of said location to the NEMA formatted data associated with the destination address; in accordance with a determination that said current GPS position of said location and the NEMA formatted data associated with the destination address do not correspond within a pre-defined territory specific tolerance limit: provide an alert to the user via the data acquisition device; receive, via the data acquisition device and after providing the alert, confirmation from the user that the destination address is correct: modify, in response to the confirmation from the user, the NEMA formatted data associated with the destination address to said current GPS position of said location; and transmit, via the data acquisition device, the modified NEMA formatted data associated with the destination address to the host system for updating of the NEMA formatted data for the destination address. a global positioning system, GPS, sensor configured to determine a GPS position comprising a latitude, a longitude, and an altitude, and a processor configured to: receive via the data acquisition device, from a host system, National Electrical Manufacturers Association, NEMA, formatted data for a destination address, the NEMA formatted data comprising a latitude, a longitude and an altitude associated with the destination address;
