The shapefile was created in ArcView using 250 m GLORIA sidescan image (gloria.tif) to identify areas of high backscatter. Only those areas that were not associated with steep slopes (derived from comparing This GIS data layer with a slope steepness map derived from the multibeam bathymetry) nor mass-wasting deposits (derived from comparing This GIS data layer with the masswasting shapefile) were included in This GIS data layer.gloria.tifUnknowngloria_bright.shpMetadata imported.C:\GOMGIS\data\sidescan\interpretation\gloria\gloria_coverage.shp.xml20040929Paskevich, V.2000Gulf of Mexico GLORIA sidescan sonar geologic interpretation: ArcView data coverages1.0Open-File Report00-019Woods Hole Science Center, Woods Hole, MAU.S. Geological SUrvey, COastal and Marine Geology Program1 CD-ROMremote-sensing imagehttp://pubs.usgs.gov/of/of00-019/Dataset projected froom NAD27 to NAD83 using Arctoolbox 9.0.20051213gloria_bright.shpgloria_bright_nad83.shpThe data layer has been checked for topological consisitency (Clean and Build completed).
