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 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.

We claim: 1. A method of collecting mapping data, comprising: positioning a target at a first point of interest; operating a measuring device at a reference position which is spaced from the first point of interest to determine a distance from the reference position to the target located at the first point of interest, wherein the operating step comprises: firing a pulse of laser radiation from the measuring device at the target, detecting a portion of the pulse of laser radiation that is reflected from the target back to the measuring device, determining a time of flight for the reflected portion of the pulse of laser radiation, and determining a distance between the measuring device and the target based on the determined time of flight; recording information about the first point of interest with a data collection device that is located at the first point of interest; and recording the determined distance in the data collection device. 2. The method of claim 1, wherein the step of recording the determined distance comprises wirelessly transmitting the determined distance from the measuring device to the data collection device. 3. The method of claim 1, further comprising: determining an azimuth angle of a line passing from the measuring device to the target; and recording the azimuth angle in the data collection device. 4. The method of claim 3, wherein the step of recording the azimuth angle comprises wirelessly transmitting the azimuth angle from the measuring device to the data collection device. 5. The method of claim 1, further comprising: determining an inclination angle of a line passing from the measuring device to the target; and recording the inclination angle in the data collection device. 6. The method of claim 5, wherein the step of recording the inclination angle comprises wirelessly transmitting the inclination angle from the measuring device to the data collection device. 7. The method of claim 1, further comprising: operating the measuring device located at the reference position to determine a distance between the reference position and a target located at a second point of interest; recording information about the second point of interest with a data collection device that is located at the second point of interest; and recording the determined distance between the reference position and the target at the second point of interest in the data collection device. 8. A method of collecting mapping data, comprising: operating a measuring device located at a reference position to determine a distance between the reference position and a first point of interest that is spaced from the reference position, wherein the operating step comprises: firing a pulse of laser radiation from the measuring device at a target located at the first point of interest, detecting a portion of the pulse of laser radiation that is reflected from the target back to the measuring device, determining a time of flight for the reflected portion of the pulse of laser radiation, and determining a distance between the measuring device and the target based on the determined time of flight; recording information about the first point of interest with a data collection device that is located at the first point of interest; and recording the determined distance in the data collection device. 9. The method of claim 8, wherein the step of recording the determined distance comprises wirelessly transmitting the determined distance from the measuring device to the data collection device. 10. The method of claim 9, further comprising: determining an azimuth angle of a line passing from the measuring device to the first point of interest; and recording the azimuth angle in the data collection device. 11. The method of claim 10, wherein the step of recording the azimuth angle comprises wirelessly transmitting the azimuth angle from the measuring device to the data collection device. 12. The method of claim 10, further comprising: determining an inclination angle of a line passing from the measuring device to the first point of interest; and recording the inclination angle in the data collection device. 13. The method of claim 12, wherein the step of recording the inclination angle comprises wirelessly transmitting the inclination angle from the measuring device to the data collection device. 14. The method of claim 8, further comprising: operating the measuring device located at the reference position to determine a distance between the reference position and a second point of interest; recording information about the second point of interest with a data collection device that is located at the second point of interest; and recording the determined distance between the reference position and the second point of interest in the data collection device. 15. The method of claim 14, wherein the step of recording the determined distance between the reference position and the second point of interest comprises wirelessly transmitting the distance from the measuring device to the data collection device.
