Bathymetry--Offshore of Salt Point Map Area, California

This part of DS 781 presents data for the bathymetry and shaded-relief maps of the Offshore of Salt Point map area, California. Raster data file is included in "Bathymetry_OffshoreSaltPoint.zip", which is accessible from http://pubs.usgs.gov/ds/781/OffshoreSaltPoint/data_catalog_OffshoreSaltPoint.html.

The bathymetry and shaded-relief maps of the Offshore of Salt Point Map Area, California, were generated from bathymetry data collected by California State University, Monterey Bay (CSUMB), and by Fugro Pelagos. Mapping was completed between 2007 and 2010, using a combination of 200-kHz and 400-kHz Reson 7125, and 244-kHz Reson 8101 multibeam echosounders, as well as 468-kHz SEA SWATHPlus interferometric system. These mapping missions combined to collect bathymetry from about the 10-m isobath to beyond the 3-nautical-mile limit of California's State Waters. NOTE: the horizontal datum of the bathymetry data (NAD83) differs from the horizontal datum of other layers in this DS (WGS84). These data are not intended for navigational purposes.

本数据集（DS 781）的此部分提供了加利福尼亚州盐角近海制图区的水深与阴影晕渲地形图数据。栅格数据文件包含于"Bathymetry_OffshoreSaltPoint.zip"中，可通过http://pubs.usgs.gov/ds/781/OffshoreSaltPoint/data_catalog_OffshoreSaltPoint.html获取。
加利福尼亚州盐角近海制图区的水深与阴影晕渲地形图，由加州州立大学蒙特雷湾分校（California State University, Monterey Bay, CSUMB）以及Fugro Pelagos采集的水深数据生成。制图工作于2007年至2010年间完成，所用设备包括200kHz与400kHz的Reson 7125多波束测深仪、244kHz的Reson 8101多波束测深仪，以及468kHz的SEA SWATHPlus干涉测量系统。本次测绘任务采集的水深数据覆盖范围约从10米等深线至超出加利福尼亚州水域3海里的边界。注意：本次水深数据的水平基准面为NAD83，与本数据集中其他图层的水平基准面WGS84不一致。本数据集并非为导航用途而设计。
