Within the program, maps are entered from a digitizing tablet and contour areas and map volumes are computed. Plan includes an easy interface that guides the user through the program. Plan can analyze isopach, pore volume, hydrocarbon pore volume, and structure maps. For structure maps to be analyzed in Plan, the contours must have closure. For structure maps, contour areas are computed, but volumes are not.
Scales can be in English or metric units.
Faults, sink holes, and well locations can all be included on the map. While digitizing, Plan graphs contours, faults, sink holes, and well locations. Plan can be used with a variety of digitizing tablets connected to the computer through a serial port. Once a map is digitized and saved, it can later be reloaded and contours edited. Once a map has been defined, Plan presents two tables.
