Historical Photographic Analysis (HPA) is a GIS-based tool employed by the U.S. Army Geospatial Center (AGC) to identify features and activities that are potential environmental concerns for current and former U.S. military installations, in order to preserve landscapes for the future. These installation environments are dynamic and material used long ago may be hidden beneath the surface. Recent imagery may provide only a partial understanding of past land-use changes and activities at any given location, therefore analysts utilize historical aerial photography and imagery to address environmental concerns related to land use change. AGC’s Environmental Analysis Team analyzes historical data in conjunction with current imagery to reveal potential environmental concerns such as chemical warfare material, unexploded ordnance, radioactive material, landfill locations, surface features, and shoreline changes. The findings are integrated into a GIS, enabling users to view multi-layer time sequenced data in a digital environment. Recommendations and decisions can be made based on these analyses and findings, aiding with the restoration and remediation efforts of military installations.
