THREE-DIMENSIONAL GIS FOR THE EARTH SCIENCES

Earth scientists are frequently confronted with problems that involve 3-dimensional phenomena, but up until now the main computerized geoprocessing tool available to them has been the 2-dimensional GIS. New 3-dimensional geoprocessing capabilities are being developed and will be in their hands in 1989. These systems address a class of problems that could not be dealt with before and will provide answers to questions that we did not realize we could ask.
