COMPUTER GRAPHICS DEMONSTRATION -- AREA COAL AVAILABILITY STUDIES

A computerized mapping system was developed to provide procedures for the rapid and inexpensive display of coal reserve data. Mapping system output consists of two types of maps, point distribution and contour (isopleth), which can be produced for data (coal analyses) associated with a point location (outcrop, drill core, or mine samples). These locations can be in the form of latitude and longitude or Universal Transverse Mercator (UTM) grid coordinates. The primary advantage of this system is that it enables the display of a rapidly changing data base and computerized map generation without the intermediate steps of digitizing and overlaying to produce base maps. The mapping system is applicable to any regional mineral reserve or resource study for which point location data are available.
