What is claimed is: 1. A location measurement system, comprising: a GPS receiver configured for attachment to a person and for determining earth location of the person; at least one of a display and an audio feedback that is attachable to the person; memory storing map data wherein the map data includes 3-D topographical information; and a processor configured to process the earth location and the map data to instruct display of a person's current location with a map on the display, detect contact with ground based upon movement of the person over the ground, determine vertical drop of the person based upon the movement of the person over the ground during at least one time interval in which lack of contact with the ground is detected followed by subsequent detection of contact with the ground; and compare the vertical drop of the person to a vertical drop determined for another person; wherein the comparison of the vertical drop of the person to the vertical drop determined for another person is configured for output to the at least one of the display and the audio feedback. 2. The system of claim 1, the GPS receiver, memory and processor being configured within a watch wherein the display is the display of the watch. 3. The system of claim 1, the GPS receiver further configured to determine speed of the person, the processor configured to instruct output of speed to the person on the at least one of the display and the audio feedback. 4. The system of claim 1, the GPS receiver configured to determine distance traveled of the person, the processor further configured to instruct output of distance traveled to the person on the at least one of the display and the audio feedback. 5. The system of claim 1, further comprising a vibrational sensor configured to determine the contact and the lack of contact with the ground. 6. A location determining system, comprising: a housing configured for attachment to a person; a GPS receiver configured with the housing for determining earth location; memory configured with the housing and storing map data wherein the map data includes 3-D topographical information; at least one of a display and an audio feedback con figured for attachment to the person; and a processor configured with the housing to process earth location and the map data to determine location of the person, to detect contact with ground based upon movement of the person over the ground, to determine a vertical drop of the person based upon movement of the person over ground during at least one time interval in which lack of contact with the ground is detected followed by subsequent detection of contact with the ground, and to instruct display of the person's location on a map, wherein the processor is further configured to compare the vertical drop of the person to a vertical drop of another person; wherein the comparison of the vertical drop of the person to the vertical drop of the another person is output to the at least one of the display and the audio feedback. 7. The system of claim 6, wherein the location determining system comprises at least one display, and wherein the display is positioned proximate to or integral with the housing. 8. The system of claim 6, further comprising an altimeter for determining altitude of the housing. 9. The system of claim 8, wherein the location determining system comprises at least one display, and wherein the display includes a watch for displaying one or both of the person's location and the altitude. 10. The system of claim 6, the processor configured to determine speed associated with movement of the housing. 11. The system of claim 10, wherein the location determining system comprises at least one display and wherein the display includes a watch for displaying one or both of the person's location and the speed. 12. The system of claim 6, further comprising a wireless transmitter configured with the housing to transmit data indicative of location to a remote location. 13. A performance measurement system, comprising: a first GPS receiver configured for attachment to a first person and for determining performance data for the first person, wherein the performance data of the first person comprises a vertical drop determined based upon movement of the first person over ground during at least one time interval in which lack of contact with the ground is detected followed by subsequent detection of contact with the ground; a memory for storing performance data for a plurality of people, including at least the first person; a processor coupled to the first GPS receiver, the processor configured to process the performance data for the first person and compare the performance data of the first person with performance data of at least one other person within the plurality of people; and at least one of a display and an audio feedback for attachment to the first person; wherein the comparison of the performance data of the first person with the performance data of the at least one other person is output to the at least one of the display and the audio feedback. 14. The performance measurement system recited in claim 13, wherein the performance data includes at least one of vertical drop, power, speed, drop distance, location, acceleration, and energy. 15. The performance measurement system recited in claim 13, wherein the memory is a server that is remote from the first GPS receiver. 16. The performance measurement system recited in claim 15, further comprising a second GPS receiver for attachment to a second person and for determining performance data for the second person, and a second at least one of a display and an audio feedback for attachment to the second person, and wherein the processor is further configured to process the performance data for the second person and compare the performance data of the second person with performance data of at least the first person; wherein the comparison of the performance data of the second person with performance data of at least the first person is output to the second at least one of the display and the audio feedback.
