ABSTRACT
The Global Spatial Data Model (GSDM) is an arrangement of time-honored solid geometry equations and proven mathematical procedures. The GSDM accommodates measurements and observations that have been reduced to their rectangular components, and reliable geometrical computations are performed in 3-D space without being distorted by the model. The GSDM provides a way to “level the playing field” in that raw data can be preprocessed to a common geometrical standard by knowledgeable specialists in various disciplines. The GSDM is also applicable when performing location and accuracy computations in a dynamic environment in which at least one if not both are moving relative to the Earth or relative to each other. The GSDM accommodates both network and local accuracies. The user remains in complete control of the map products generated from the GSDM database. Maps can be plotted directly from local coordinate differences, derivative map projection coordinates, or geodetic values.
