    Feature discrimination/identification based upon SAR return variations

    A study of the statistics of The look-to-look variation statistics in the returns recorded in-flight by a digital, realtime SAR system are analyzed. The determination that the variations in the look-to-look returns from different classes do carry information content unique to the classes was illustrated by a model based on four variants derived from four look in-flight SAR data under study. The model was limited to four classes of returns: mowed grass on a athletic field, rough unmowed grass and weeds on a large vacant field, young fruit trees in a large orchard, and metal mobile homes and storage buildings in a large mobile home park. The data population in excess of 1000 returns represented over 250 individual pixels from the four classes. The multivariant discriminant model operated on the set of returns for each pixel and assigned that pixel to one of the four classes, based on the target variants and the probability distribution function of the four variants for each class

    Multiple data set integration and GIS techniques used to investigate linear structural controls in the southern Powder River Basin, Wyoming

    Lineaments in the Powder River Basin were mapped and categorized from Landsat TM imagery, a Digital Elevation Model (30 m), and Digital Line Graph (DLG) hydrology files. A GIS program was written using DLG information to eliminate those lineaments that were within 20° of roads and railroads. The DLG and DEM information was further used to stratify the topographic lineaments into slope-breaks, ridge-tops, or valleys. Rose diagrams created for each class of lineaments give important clues on the timing of their formation. The major northwest and northeast trends that these lineaments follow appear to correspond with those identified by previous works. Comparisons with subsurface data suggests that the concentration of lineaments is strongly coincident with gravity and magnetic highs and lows, possibly representing the surface expression of basement-rooted structure. Lastly, the location many reservoirs in the basin also coincide with higher concentration of lineaments over gravity and magnetic highs.;This project was partially funded by the Schumaker Fund, donated by Dr. and Mrs. Robert Schumaker. Also, supplemental funding was given by the American Society for Photogrammetry and Remote Sensing. I would like to thank all of those involved in supporting both of these funds. Their donations has made it possible for continuing research of GIS and geology
