Notable Environmental Features In Some Historical Aerial Photographs From Ashley County, Arkansas, Don C. Bragg, Robert C. Weir Jr.
Notable Environmental Features In Some Historical Aerial Photographs From Ashley County, Arkansas, Don C. Bragg, Robert C. Weir Jr.
Journal of the Arkansas Academy of Science
A collection of 1939 aerial photographs from Ashley County, Arkansas was analyzed for its environmental information. Taken by the US Department of Defense (USDOD), these images show a number of features now either obscured or completely eliminated over the passage of time. One notable feature is the widespread coverage of "sand blows" in the eastern quarter of the county, suggesting a major soil liquefaction field consistent with strong seismic activity (magnitude 6.0 on the Richter Scale). Also seen in these photographs are the vestiges of the large prairies once found on the Pleistocene terraces of southern and eastern Arkansas. The …

Assessing The Spatial Accuracy Of Applanix DssTm Model-301 Sensor Stereo Imagery Using A Survey Gps Ground Control Network, Robert C. Weih Jr., David W. Rowton
Journal of the Arkansas Academy of Science
During the past decade, Geographic Information Systems (GISs) have become widely used in many disciplines and that has created demands for accurate high-resolution digital data, especially digital imagery. Photogrammetry has emerged as one of the most important disciplines employed in the collection of spatially related information for use in GIS databases, especially for terrestrial landscapes. This study assessed the horizontal and vertical accuracy of the Applanix Digital Sensor System (DSS"") 301 orthophotographs. The study area was located on the University of Arkansas at Monticello campus and included 950 acres. To assess the spatial accuracy of the DSS, 56 Ground Control …
