Digital spatial data of former Air Force Plant 36 in Evendale, Ohio, were compiled from existing digital and paper maps for U.S. Air Force Aeronautical Systems Center, headquartered at Wright-Patterson Air Force Base, Ohio. The data are in the Ohio south state-plane coordinate system, North American Datum of 1983, in an ARC/INFO geographic information system format. The data comprise 32 layers, which include boundaries, topography, well locations, and natural and cultural features. These data can be useful for remediation projects on former AFP36. Most of these layers are at scales of 1:4,000 or greater and provide detail needed for spatial analysis. The data were compiled for the purpose of inclusion in the technical information system operated by ASC.
