 In a cooperative effort between the Teale Data Center GIS Solutions Group and the California Department of Fish and Game, bathymetric data sets from various sources were gridded, contoured, and then plotted using ESRI software.
 Among the contributing data sets, some six million National Ocean Service Hydrographic Survey depth points were processed for the entire California coast. Due to the volume of input data, processing was performed in 100-kilometer-by-100-kilometer zones. The ArcInfo commands TopoGrid and LatticeContour were used as primary interpolation algorithms. ArcInfo and ArcView facilitated the checkplots and data visualization.
In Northern California, especially dense hydrographic survey data provided excellent near shore detail for the gridding and contouring processes. This poster, produced using ArcView 3.2, ArcView Spatial Analyst 2, and ArcView 3D Analyst 1, illustrates some of the spatial data now available to assist with marine resources research and management.
