A. K. TURNER Department of Geology and Geological Engineering
Colorado School of Mines Golden, Colorado 80401 USA Geology deals
with three-dimensional data. Geoscientists are concerned with three
dimensional spatial observations, measurements, and explanations of
a great variety of phenomena. The representation of
three-dimensional data has always been a problem. Prior to
computers, graphical displays involved specialized maps,
cross-sections, fence diagrams, and geometrical constructions such
as stereonets. All were designed to portray three-dimensional
relationships on two-dimensional paper products, and all were time
consuming to develop. Until recently, computers were of little
assistance to three-dimensional data handling and representation
problems. Memory was too expensive to handle the huge amounts of
data required by three-dimensional assessments; computational
speeds were too slow to perform the necessary calculations within a
reasonable time; and graphical displays had too Iowa resolution or
were much too expensive to produce useful visualizations. Much
experience was gained with two-dimensional geographic information
systems (GIS), which were applied to many land-use management and
resource assessment problems. The two-dimensional GIS field matured
rapidly in the late 1980's and became widely accepted. The advent
of the modern computer workstation, with its enhanced memory and
graphical capabilities at ever more affordable prices, has largely
overcome these earlier constraints.
