Our goal is to provide an introduction to the study of minimal energy problems, particularly
from the perspective of generating point configurations that provide useful discretizations of …

通过梳理近十多年来地球剖分格网的相关研究文献, 从剖分建模(四边形剖分,
等积剖分和立体剖分), 编码计算(层次编码运算, 填充曲线编码运算和整数坐标编码运算) …

The creation of a digital representation of the Earth and its associated data is a complex and
difficult task. The incredible size of geospatial data and differences between data sets pose …

This survey discusses recent developments in the context of spherical designs and minimal
energy point configurations on spheres. The recent solution of the long standing problem of …

There are many ways to generate a set of nodes on the sphere for use in a variety of
problems in numerical analysis. We present a survey of quickly generated point sets on …

By analyzing the related literatures on the earth tessellation grid (ETG) in recent 10 years,
the research achievements in this field are systematic reviewed in four aspects, ie. the earth …

We define a family of random sets of points, the Diamond ensemble, on the sphere S 2
depending on several parameters. Its most important property is that, for some of these …

Geospatial sensors are generating increasing amounts of three-dimensional (3D) data.
While Discrete Global Grid Systems (DGGS) are a useful tool for integrating geospatial data …

Three-dimensional (3D) buffer analysis is among the basic functions of 3D spatial analysis,
and it plays an important role in 3D geographic information systems. The rapid development …

为克服传统QTM 格网面积变形较大的缺陷, 在“纬线法” 剖分的基础上, 引入变经纬度等面积剖分
的思想, 提出了一种新的等面积改进剖分模型. 该模型通过调整纬线的位置 …
