dc.descriptionTechnical Report
dc.description.abstractThe Terrestrial Geospatial Remote Assessment for Ingress Locations (GRAIL) portion of the Army Terrestrial Environmental Modeling and Intelligence System Science and Technology Objective–Research (ARTEMIS STO-R) program was developed to use remote methods of terrain analysis to search for areas suitable for vehicle or aircraft maneuverability, based on slope, roughness, vegetation, soil type, and wetness, and to also perform direct classification of imagery based on soil strength. The product of the GRAIL project was a software program entitled GRAIL Tools. Using a series of filters, GRAIL Tools first eliminates areas of unsuitable slope, land use, obstacles, and vegetation. The algorithms for these filters, using both unsupervised and supervised classification approaches, were applied and trained by a limited amount of ground truth strength measurements to improve GRAIL Tools’ site selection capabilities. GRAIL Tools then searches for sites that meet geometric criteria for landing and drop zones, the final result being a map of potential landing and drop zones superimposed over satellite imagery. The first generation of GRAIL Tools has proven capable of identifying austere landing and drop zones using remote assessment techniques. GRAIL Tools has been integrated in to the U.S. Army’s Situational Awareness Geospatially Enabled (SAGE) software platform.en_US
