“…A role of the U.S. Army Engineer Research and Development Center (ERDC) in the OLS Demonstration Program was to verify the capability of the Boeing OLS-MS software for locating large, smooth, flat, obstructionfree areas (Ryerson and McDowell 2007). In that regard, ERDC evaluated the quality of four field sites at three locations: southern Indiana, Ft. Bliss, TX, and the El Centro Naval Air Facility (NAF), El Centro, CA.…”

A goal of the Air Force Research Laboratory Opportune Landing Site (OLS) program was to locate large, smooth, flat, obstructionfree areas safe for aircraft operations. The ERDC was tasked to evaluate the quality of OLSs as located by OLS Multi-Spectral (OLS-MS) software that was developed by the Boeing Company and uses Landsat multispectral imagery. ERDC conducted extensive field work evaluating OLSs in Indiana, New Mexico, and California. However, while seeking these OLS-MS-selected field sites, many other software-selected potential OLSs were casually observed not to satisfy requirements with regard to obstructions. Our objective was to evaluate a statistically valid sample of OLSs for freedom from obstructions. We utilized OLSs located by the final version of the OLS-MS software, plotted them over orthophotoquads, and assessed their intersections with obstructions within geographic information system (GIS) datasets containing natural and cultural features. A sample of OLSs was also visually evaluated to assess the accuracy of the GIS analysis process. Features in the GIS datasets often did not correspond exactly with features on the ground, a source of analysis error that may be due to digitizing uncertainty and differences in the creation dates of the images and datasets. The success of the OLS software in avoiding obstructions is presented in the results.

“…Several new approaches have been taken to improve the capability of rapidly locating OLSs from the use of satellite imagery (Manley 2001, Ryerson and McDowell 2007, Vincent and Jennings 2004. Using the approaches described by these authors, the OLS Program is demonstrating and improving upon the capability of current technology for locating satisfactory sites, with the future goal of landing airplanes without first placing "boots on the ground.…”

“…The OLS program is intended to demonstrate how existing technologies can rapidly accelerate the process of selecting OLSs using remote sensing technology and state-of-the-ground forecast tools (Ryerson and McDowell 2007). However, in the process of demonstration, techniques within the program are being improved and made more robust.…”

Abstract:The Army relies on agility and speed, including the ability to conduct air transport operations where no runways exist, and where engineers cannot be pre-positioned. One of the most difficult problems is locating large, smooth, flat, and obstruction-free areas that are sufficiently firm to support at least one aircraft operation, and preferably many. The Opportune Landing Site (OLS) program demonstrated the use of remote sensing technology and state-of-the-ground forecast tools to accelerate the process of selecting OLSs. To evaluate the quality of the selected OLSs, ground truth measurements were conducted at Fort Bliss in New Mexico. Before conducting field measurements, several sites identified by OLS software were visually inspected to evaluate and select a suitable OLS for field testing. Evaluation procedures were based on Air Force Civil Engineer Support Agency (AFCESA) recommendations for evaluating airfield pavements. Soil strength and moisture measurements were made at several locations along the OLS, and overall quality was evaluated during three seasons. Assessment software was able to predict an OLS adequate for landing a C-130, but not capable for a C-17. This was true for all three field assessments at Fort Bliss.
