Indiana Coal Quality Database (ICQD)

The Indiana Coal Quality Database is an interactive map application that allows users to search, explore, and compare coal stratigraphic data. The database was first published on CD-ROM in 2005, with an updated CD-ROM released in 2012. The dataset is a compilation of various physical and chemical parameters collected by Indiana Geological and Water Survey researchers since 1954, and is updated as new information is gathered.

Indiana Coal Mine Information System (CMIS)

The Coal Mine Information System (CMIS) is a repository for historical coal mining information in Indiana. It was developed through a cooperative agreement between the Indiana Geological Survey (IGS) and the Indiana Department of Natural Resources, Division of Reclamation. In addition to historical documents, prepared maps and reports, the CMIS has compiled digital geographic data and associated mine information such as workings maps, entrances and subsidence areas. This data is publicly accessible through an online map viewer (link below).
