Abstract

The enormous volumes of geospatial data and the need to process and distribute them cry out for a unified framework that enables their efficient storage, analysis, and a high degree of interoperability. Discrete global grid systems provide such a framework by hierarchically tessellating cells to seamlessly partition and address the globe. Since they are usually based on a regular polyhedron, they partition the entire world into as many discrete data sets as the given polyhedron has sides. In this paper, we try to reduce the number of partitions to two, which is a minimum if we want to obtain spatially convex partitions without interruptions. Two approaches are presented, based on an adjusted spherical cube and an equidistant cylindrical projection. The distortions resulting from the application of these projections are compared and guidelines are presented to improve the quality of their implementation by reducing the distortion of the continental plates and making a better mapping to the WGS84 ellipsoid.

两分区离散全局网格系统——基于调整球立方和圆柱等距投影的方法比较

海量的地理空间数据以及处理和分发这些数据的需求迫切需要一个统一的框架，以实现有效的存储、分析和高度的互操作性。离散的全球网格系统提供了这样一个框架，通过分层镶嵌单元来无缝划分和处理全球。由于它们通常基于正多面体，因此它们将整个世界划分为给定多面体有多少边的离散数据集。在本文中，我们试图将分区的数量减少到两个，如果我们想要获得没有中断的空间凸分区，这是最小的。提出了两种方法:基于调整球面立方体和等距圆柱投影。比较了这些投影在应用中产生的畸变，并提出了通过减少大陆板块畸变和更好地映射到WGS84椭球来提高其实施质量的指导方针。
