Interpolated bathymetry of Long and Tryne Fjords, Vestfold Hills, Antarctica

This GIS dataset is the result of the interpolation of bathymetry from depth measurements made in Long and Tryne Fjords in the Vestfold Hills, Antarctica (see Entry: VH_bathy_99). The Topogrid command within the ArcInfo GIS software, version 8.0.2, was used to do the interpolation. Coastline and spot height (heights above sea level) data, extracted from the Australian Antarctic Data Centre's Vestfold Hills topographic GIS dataset (see Entry: vest_hills_gis), was also used as input data to optimise the interpolation close to the coastline. See related URLs for a map showing the interpolated bathymetry.

本地理信息系统（Geographic Information System, GIS）数据集由南极维斯特福尔兹丘陵区朗峡湾与特赖恩峡湾的水深测量数据经插值处理生成（详见条目VH_bathy_99）。本次插值作业采用ArcInfo GIS软件8.0.2版本内置的Topogrid命令完成。从澳大利亚南极数据中心（Australian Antarctic Data Centre）的维斯特福尔兹丘陵地形GIS数据集（详见条目vest_hills_gis）中提取的海岸线与高程点（spot height，即海拔高度）数据，亦作为输入数据用于优化海岸线邻近区域的插值精度。可通过相关链接查看展示插值后测深地形的地图。
