This invention integrates a novel technique for mappers to efficiently collect attributes utilizing various wireless systems such as bluetooth. The wireless technique in the data-gathering device allows the flag-man/data gatherer to input useful information into the device, which can readily be available to the mapper at the other end. This invention makes the traditional mapping technique much more efficient and reliable. Due to the ability to exchange data promptly, it nearly diminishes the room for discrepancies. This device overcomes mainly two deficiencies in current mapping device: the need to use a wire to connect data recording device to a data-collecting device, and the need to use some form of oral communication (for ex. use of a radio transmission at an accident investigation site between police officers) to relay the attributes of the data being collected. This proves to be very efficient by cutting down the investigation data collection time to nearly half, especially at the times when there is heavy traffic and the accident needs to be cleared up as quickly as possible.
