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（GIS）数据集是针对南极维斯弗德丘陵区域朗峡湾与特赖恩峡湾的水深测量数据进行插值处理后得到的成果（详见条目VH_bathy_99）。本次插值作业采用版本为8.0.2的ArcInfo GIS软件内置的Topogrid命令完成。研究同时纳入从澳大利亚南极数据中心维斯弗德丘陵地形GIS数据集（详见条目vest_hills_gis）中提取的海岸线与高程点（海平面以上高度）数据作为辅助输入，以优化海岸线附近区域的插值精度。可通过相关链接查看展示插值后水深地形的地图。
