BATTOPOG is a 30-meter grid of offshore bathymetry and onshore topography assembled from USGS Digital Elevation Model (DEM) and National Oceanic and Atmospheric Administration (NOAA)/National Ocean Service (NOS) data. BATTOPSD.TIF is a shaded relief version of BATTOPOG converted to a TIFF image. This is one of a collection of digital files of a geographic information system of spatially referenced data related to the USGS Coastal and Marine Geology Program "Monterey Bay National Marine Sanctuary Project" . The data were collected and analyzed between 1994 and 2000. Purpose: These data are intended for science researchers, students, policy makers, and the general public. The data can be used with geographic information systems (GIS) software to display geologic and oceanographic information about the shallower areas of the Monterey Bay National Marine Sanctuary.

Degnan: extracted bathymetry data from NOAA (1998), gridded it in GMT (Wessel and Smith, 1998) with a 2-second grid spacing, and exported the grid values as ASCII xyz coordinates. Process_Date: 199911 Process_Step: Process_Description: W.C. Lee: converted bathymetry xyz coordinates to ArcInfo point coverage. Created ArcInfo TIN from point coverage; converted TIN to 50-m grid (Arc: TINLATTICE, quintic option). Assembled 30-m elevation grid for western part of Point Sur 30- x 60-minute quadrangle from 7.5-minute USGS DEMs. Process_Date: 199912 Process_Step: Process_Description: Note - Names of intermediate files are used in the following description for reference only; those intermediate files are not included in this dataset. F.L. Wong: Applied low-pass filter (Arc: FILTER, 2 iterations) to bathymetry grid to smooth data. Resampled bathymetry to 30 m cell size and converted to integer grid BATIG. Converted elevation grid SFBR-EL north of latitude 37 North (Graham and Pike, 1998) from datum NAD27 to NAD83 and z-units from decimeters to meters. Similarly converted Monterey elevation grid (Ramsey, 1997). In study window, built a grid mask enclosed by the coastline and the scratch boundary. With mask active, merged Point Sur, Monterey, and SFBR-EL 30-m grids as TOPOG. Converted TOPOG from floating point to integer grid TOPOIG. Merged TOPOIG and BATIG as BATTOPOG. Applied shading scheme (Mark, 1992) to grid to produce shaded relief grid BATTOPOSHDG Converted battoposhdg to TIFF image BATTOPSD.TIF.
