What does the development geologist want to do with the computer? Certainly he or she has the same needs as any other worker for general purpose business applications (word processing, spreadsheets, and so on), and these are not discussed here. In addition to these, numerous geoscience applications have been developed to make the geologist's job easier, and these are summarized in Table 1.

The major task of the geologist has always been to make maps, and this is where the first computer applications were developed and where the greatest progress has been made in refining techniques (see [[Contouring geological data with a computer]]). Computer-assisted map making can be merely posting values from the database on a basemap for hand contouring, or it can make use of one of the many specialized algorithms to compute a grid and contour that grid automatically. An intermediate approach is to digitize hand-drawn contours and compute a grid that exactly models the geologist's interpretation. The gridding step is desirable because it allows mathematical operations between surfaces (such as computing an isopach from two structure grids), volumetric reserve calculations, and three-dimensional perspective views of the surfaces, which are practically impossible to do by hand.
