Bathymetry Hillshade--Offshore Santa Cruz, California

This part of DS 781 presents data for the bathymetry and shaded-relief maps of Offshore Santa Cruz, California. The raster data file is included in "BathymetryHS_OffshoreSantaCruz.zip", which is accessible from http://dx.doi.org/10.5066/F7TM785G.
The bathymetry and shaded-relief maps of Offshore Santa Cruz, California, were generated from bathymetry data collected by the U.S. Geological Survey (USGS). Mapping was completed in 2009 using a 234-kHz SWATHplus bathymetric sidescan-sonar system. The mapping mission collected bathymetry data from about the 10-m isobath to beyond the 3-nautical-mile limit of California’s State Waters. NOTE: The horizontal datum of this bathymetry data (NAD83) differs from the horizontal datum of other layers in this data release (WGS84).

本DS 781数据集板块提供加利福尼亚州圣克鲁兹近海的水深测量数据与海底晕渲地图数据集。
该栅格数据文件收录于"BathymetryHS_OffshoreSantaCruz.zip"压缩包中，可通过链接 http://dx.doi.org/10.5066/F7TM785G 获取。
加利福尼亚州圣克鲁兹近海的水深测量数据与海底晕渲地图，由美国地质调查局（U.S. Geological Survey, USGS）采集的水深数据生成。
本次制图工作于2009年完成，采用了234 kHz的SWATHplus水深侧扫声呐系统。
本次测绘任务采集的水深数据范围约为10米等深线至加利福尼亚州管辖海域3海里界限以外区域。
注意：本批水深测量数据的水平基准为NAD83，与本次数据发布中其他图层所采用的WGS84水平基准存在差异。
