Shapefiles and Historical Aerial Photographs, Little Missouri River, 1939-2010

The data archive contains the aerial photographs and channel delineations used in our analysis. The images have been geo-referenced to the 1995 digital orthophoto quarter quadrangles as described by Miller and Friedman (2009). The separate images for each year can be viewed as a composite along with that year's channel delineation using a geographic information system (GIS). The 2003 IKONOS satellite imagery is proprietary and, therefore, cannot be served here. The channel delineations for all photo years (including 2003) and the delineation of the outer flood-plain boundary are stored as shapefiles. These shapefiles can be manipulated using GIS applications to reproduce the spatial analyses reported in Miller and Friedman (2009). This metadata record is associated with the project landing page that describes the entire data package. The seven child items on the landing page are each associated with a different repeat photography year. Each child item provides all images taken in that year and a SHP file that delineates channel location. Each year's photography consists of 4-8 scanned and referenced aerial photographs or digital satellite imagery in a geoTIFF format. SHP files from any year can be overlaid on top of the images to visualize change in channel location. TIFF images and associated SHP files are included as attachments or external sources and can be downloaded directly from the ScienceBase page.
