The aim was to display the quantity of coal available at various sulfur levels. The study areas were in the Appalachian Coal Region and, in particular, in a two county area in Maryland. Values for sulfur content, bed thickness, and quantity of coal were manipulated and mapped using several computer mapping programs. The problem definition, computer program used, study area selection and data acquisition, and the graphic techniques used are covered. The study areas and data used, and the computer maps produced are discussed in some detail. The step by step description of the mapping procedures used for the study areas, the references, and the technical aspects of program development are presented.
