陆海地理要素空间差异对比研究

Comparative Research on Spatial Differences Between Terrestrial and Marine Geographical Features

在陆地和海洋统筹联动发展的趋势下,多尺度、多时相、多源的陆海基础地理信息数据的交互共享变得越来越重要;然而陆海地理要素的空间差异给二者的融合和使用带来了困难。以地形图和电子海图为例进行对比分析,着重从二者的空间表现角度进行差异比较,并深入分析了其产生的原因,为解决陆海地理数据空间差异和实现数据融合共享打下基础。

Under the trend of the integrative development of land and marine areas,the interaction and sharing of multi-scaled,multi-temporal,and multisource terrestrial and marine basic geographic information are becoming more and more important.However,spatial differences between topographic maps and electronic charts made it difficult to share and use.Taking topographic maps and electronic charts for example,this paper compared mainly the spatial differences between them,and analyzed the causes.This study could provide a good foundation for the solution of the difference and spatial fusion of terrestrial and marine multi-source geographical data.
