Western Coastal and Marine Geology
This data catalog has been updated from an earlier open-file report 2007-1271 (version 1.0). In this updated catalog, each GIS data file is listed with a brief description, links to figures, metadata files, and downloadable files. The data were compiled in ArcInfo (version 9.1 ESRI, 2005). Raster data layers are either ASCIIRASTER or registered TIFF images in the UTM Zone 11 coordinate system with datum WGS84. Point, line and polygon features are in shapefile format, and are projected in UTM Zone 11 coordinates with horizontal datum WGS84. We recommend you create a single new folder within which to unzip the files you want to use.
The downloadable files have been compressed with WinZip. The .zip file for a TIFF image includes the image (.tif) and the world registration file (.tfw). The ASCIIRASTER .zip file contains the ascii file (.asc) and projection file (.prj). The .zip for a shape file includes .aux, .dbf , .shp, .shx, .sbx, .sbn, and .prj files.
This new data catalog also provides new bathymetry grids that correct a vertical offset within the older bathymetry data sets available in 2007-1271 (version 1.0).
