Since 1980, the Indiana Geological Survey has collected coal stratigraphic data in accordance with the National Coal Resources Data System. This cooperative project with the U.S. Geological Survey generates, updates, and maintains coal resource information, including coal location, thickness, depth, stratigraphic position, and surrounding rock data. The Indiana Geological Survey’s Coal Stratigraphic Database provides location and stratigraphic information for 13,722 public point-source coal data in southwestern Indiana. The Indiana Geological Survey’s Coal Stratigraphic Database 2011 interactive application is a visual presentation of the database. It allows users to interactively search, explore, and compare coal stratigraphic data. These data are important for regional coal resource evaluation and can be used by the public, industry, and state and federal governments.
