This interactive web application allows users to locate historical photographs of buildings, people, and places by their spatial extent or the 'viewing area' of each photograph. Users can locate all images of a specific building by clicking on a point on the map or by viewing the focal points individually. This is a great tool if you are doing research of a specific area. The application was built using the ArcGIS JavaScript SDK and Esri's Calcite Design System framework. Click Here to view the interactive map!
