Aerial photographs were taken along the Little Missouri River in 2003, however the 2003 IKONOS satellite imagery is proprietary and therefore cannot be served here. The channel delineations for all years, including 2003, and the delineation of the outer flood-plain boundary are stored as shapefiles and are included in this data release. 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 overlaid 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 a geographic information system (GIS) application.
