1_README.TXT Continental Shelf GIS for the Monterey Bay National Marine Sanctuary By Florence L. Wong(1) and Stephen L. Eittreim(1) 2001 Open-File Report 01-179 Version 1.0 U.S. Department of the Interior Gale Norton, Secretary U.S. Geological Survey Charles G. Groat, Director (1) U.S. Geological Survey, Menlo Park, California 94025 This report is preliminary and has not been reviewed for conformity with U.S. Geological Survey editorial standards or with the North American Stratigraphic Code. Any use of trade, product, or firm names is for descriptive purposes only and does not imply endorsement by the U.S. Government. INTRODUCTION The U.S. Geological Survey (USGS) mapped and sampled the seafloor of the shelf areas of the Monterey Bay National Marine Sanctuary (MBNMS) between 1994 and 2000 to characterize the sanctuary's geologic environment. The focus of the studies is on the broad, flat continental shelf between San Francisco, California, to the north and Point Sur, California, to the south. This area is shallower than 200 m and covers approximately 3,000 sq km or 20 percent of the areal extent of the sanctuary. This compilation consists of the digital data sets from the studies assembled as geographic information system (GIS) files. The data include seafloor mapping, sample collection and analysis, and oceanographic processes. The interpretive reports from this study are available in a separate volume (Eittreim and Noble, 2002). REVISIONS AND UPDATES This GIS compilation will be revised and updated as new data become available. The most flexible way to do this will be to post changes on the internet (online). Version 1.0 will be published as a CD-ROM and will also be published online at http://geopubs.wr.usgs.gov/open- file/of01-179/. All future revisions will be published only online. The hosting site could change; if there is no forwarding link, go the USGS home page http://www.usgs.gov and search for of01-179. FILE AND DATA FORMATS Text files (.txt) on the CD-ROM and web site may be viewed without special software. Hypertext mark-up language files (.html) require a browser such as Netscape Communicator or Internet Explorer. GIF (.gif), JPEG (.jpg) or TIFF (.tif) images may be viewed by many common image software packages. The data files require ESRI ArcExplorer, ArcView, or ArcInfo. The data files can be accessed by these three applications directly from the CD-ROM. The source file for ArcExplorer, an application that ESRI licenses without charge for Windows operating systems, is included under the 'aexplore' directory. ArcView and ArcInfo are licensed applications that must be purchased. The data were compiled in ArcInfo (version 8.0.2, ESRI, 1982-2000), a commercial GIS, in the UTM Zone 10 coordinate system with datum NAD83. Raster data layers are in ArcInfo GRID format or are registered TIFF images. Point, line and polygon features are in ArcInfo COVERAGE. Shapefiles were generated for those coverages where the shape format did not degrade the data excessively. Each data layer is accompanied by FGDC-compliant metadata and an overview map. FILE ORGANIZATION Top level files: 1_readme.txt - this file 2_montgisx.html for X = 2-6; description of GIS 3_catalog.html - contents of the GIS 4_reference.html - bibliographic references autohtml.exe - Windows autoplay file autorun.inf - Windows autoplay file id.ico - Windows icon file index.html - browser startup file montgis.apr - project file to view data layers for ArcView users montgis.aep - project file to view data layers for ArcExplorer users showhtml.ini - Windows autoplay file sitemap.txt - directory listing version_history.txt - revision information Top level directories: aeplore - Source file and description for ArcExplorer 2.0.8 application for users of Windows NT/95/98 or higher data - ArcInfo data coverages, grids, and images with metadata files (.TXT). These files are in accessible to ArcInfo or ArcView directly from the CD-ROM or from http://geopubs.wr.usgs.gov/open-file/of01-179/data/. exp_arc - ArcInfo export files; available on the web site only html - subordinate web pages images - .gif,.jpg: images referenced by documents in this publication legends - .avl: ArcView legend files for selected data sets shape - Selected shapefiles, copies of projection (.prj), and metadata (.txt) files for use with ArcView and other applications that read .shp format files. Not all coverages could be converted to shapefiles because of the file name and item name character limits. If a coverage has more than one feature (for example polygons and lines), only one feature was converted to a shapefile. Subdirectories: The following subdirectories appear under 'data'; only selected ones appear under 'shape': backscat - sidescan sonar backscatter TIFF images and registration or world file; QUAD75: index coverage for image quadrangles basemaps - Coastline, sanctuary boundary, latitude/longitude graticules at 1-degree, 15-minute, and 7.5-minute intervals battopo - Elevation data below and above sea level as contour coverages and raster or grid files. geology - Earthquake epicenters, seafloor geologic map, Holocene sediment thickness, regional structure navigatn - Navigation tracklines, photo locations, instrument mooring sites samples - Sediment sample locations, results from analyses of foraminifers, hydrocarbons, mass and sediment accumulation, grain size from current study. Dredge sample descriptions from previous work. shaderel - Gray shaded-relief TIFF images based on elevation grids in battopo.
