This paper will present the results of a new mapping and drafting technology utilizing the Z Max GPS Survey System at Tall Jalul, Jordan. This new GPS system is superior to earlier systems in that, among other things, it locks on to a larger number of satellites (both U.S. and Russian) which enables a more accurate location of geographic points-to a scale of centimeters. It employs ADAPT-RTK-Automatic Decorrelation and Parameter Tuning and Real Time Kinematic positioning. The geographical data from this new GPS system can be used by a new graphic software that can create 3D images that can be manipulated in a numbers of way for research and publishing. This new GPS system has been used successfully in the field of paleontology for mapping and creating 3D images of dinosaur skeletons, including small bones and teeth-it holds tremendous potential for archaeology. Its potential lies in the area of more rapid and accurate mapping and drafting, plus the data are all in a digital format for easy exchange with scholars. The paper will conclude with brief discussion of how this new technology might be integrated into the goals of ETANA.
