A bathymetric Digital Elevation Model (DEM) of Newcomb Bay, Windmill Islands

A Digital Elevation Model (DEM) of Newcomb Bay, Windmill Islands and terrestrial and bathymetric contours derived from the DEM. The data is stored in a UTM zone 49(WGS-84) projection.Heights are referenced to mean sea level.It was created by interpolation of point data using Kriging. The input point data comprised soundings and terrestrial contour vertices. THE DATA IS NOT FOR NAVIGATION PURPOSES.

本数据集包含风车群岛（Windmill Islands）纽科姆湾（Newcomb Bay）的数字高程模型（Digital Elevation Model，DEM），以及由该DEM衍生得到的陆地与水深等值线。该数据采用通用横轴墨卡托投影（UTM）第49带（WGS-84坐标系）存储，高程基准为平均海平面。本数据集通过克里金（Kriging）插值法对输入点位数据进行插值生成，输入点位数据涵盖测深数据与陆地等值线顶点数据。本数据不得用于导航用途。
