摘要
本文简要介绍地图投影的类型及其变换的代价。解释了为什么高斯投影会成为现在GIS的空间数学基础的历史原因,并详细分析了为什么高斯投影不能作为大 GIS的空间数学基础的原因,由此,在作者多年研究的基础上,提出了适合大型GIS的空间数学模型,并详尽地分析了本模型的优点。
This paper first casts some light on the type the map - rejection and transform between the map - projections, then explains why the Gauss - projection was widely used for GIS and its historical reasons. Then comes the reasons that Gauss projection can't match the need of large GIS. Based on the above analyses, the author comes up with his solution and the advantages of his model.
