Fully Automated Compilation of Gravity and Geophysical Maps.

摘要

A wide variety of gravity and geophysical maps can be produced by fully automated methods. The locations of gravity measurements,gravity anomaly values,gravity anomaly contours,continental outlines,title,legend,labels,and other data to be shown on the maps are computer generated,then drawn by automatic plotting equipment. This procedure is used to prepare charts showing the density and distribution of gravity data holdings,contoured gravity anomaly maps and other graphics needed for gravity data evaluation and mean anomaly prediction purposes,maps of gravity station elevations used as vertical control in topographic map compilation,and maps of glacial ice thickness for geophysical analysis.
