    <abstract lang="eng" displayLabel="Abstract">This raster dataset is a 20-meter resolution grid containing shaded surface relief (hillshade) bathymetry data for Monterey Bay, California. These data have been low-pass filtered. Grids are provided in GCS WGS 84 and UTM Zone 10 (NAD 83) projections. This layer is part of the GIS Data of the Monterey Bay collection, a compilation of data and imagery of the Monterey Bay area, including coastline, imagery, and bathymetry.</abstract>
    <abstract lang="eng" displayLabel="Purpose">This collection of data provides documented layers of of the Monterey Bay to persons/institutions of interest throughout the research and educational communities. These maps help define the geological variability of the seafloor and provide a detailed framework for future research, monitoring, and management activities.</abstract>
    <note lang="eng" displayLabel="Preferred citation">Hatcher, G (1998). 20-Meter Hillshade Bathymetric Grid (Filtered): Monterey Bay, California, 1997. Monterey Bay Aquarium Research Institute. Available at: http://purl.stanford.edu/ts626mr4994</note>
    <note displayLabel="Supplemental information">All data are registered to the WGS84 datum with two versions of each feature, image, and grid coverage included in the collection. One is in a Geographic (decimal degrees) coordinate system and the second is in a Universal Transverse Mercator (UTM) zone 10 projection.

For strict accuracy and hard-copy production requiring feature, grid, and/or image data, the UTM projection coverages should be used. In fact, some ArcView functions will not be available unless the data are displayed in a projection. This is because a Geographic Coordinate System is NOT a projection but rather a spherical coordinate system dealing directly in latitude and longitude.  However, at the scale of maps covering Monterey Bay, the errors produced by ignoring this fact are small. 

NOTE: To most easily use the grid data, the ArcView Spatial Analyst extension should be installed on your system.</note>
