There is interest in ways of displaying the quantity of coal available at various sulfur levels. It was felt that computer mapping of the coal data might provide a relatively quick and inexpensive tool. The mapping was accomplished using the SYMAP computer program. The report contains eight sections: introduction to SYMAP, preparation of packages, map package electives, user subroutine and advanced uses, programming and systems guide, the SYMVU program, the GRID program, and program modifications. This includes all of the technical material necessary to prepare, interpret, and use the three programs, as well as the program modifications made during the project.
