Shapefiles and Historical Aerial Photographs, Little Missouri River, 1966

8 aerial photographs were taken along the Little Missouri River in 1966. All images were geo-referenced to the 1995 digital orthophoto quarter quadrangles as described by Miller and Friedman (2009). Both the flood plain and active channel of the river were delineated on the 1995 digital orthophoto quadrangles and overlain on rectified photos. ArcGIS was used to draw the polygons that delineate the flood plain and active channel; the delineation was saved as a SHP file. The separate images (geoTIFFs) can be viewed as a composite along with that year's channel delineation (SHP file) using ArcGIS, or any other geographic information system (GIS) compatible program.
