- WMS-Based Flow Mapping Services
- ABSTRACT Flow Mapping, also known as spatial interaction data visualization, has become widely used for exploratory spatio-temporal data analysis to understand complex spatial phenomena such as human migration, commercial trading, and social networks. The unitary flow mapping architecture, in wh ...
- SPATIAL SCENE SIMILARITY ASSESSMENT ON HADOOP
- Spatial Scene Similarity Assessment (SSSA) is an essential problem in spatial analysis, spatial query, and map generalization, etc. In SSSA, spatial scene similarity needs to be compared between query spatial scene and each candidate spatial scene. The computational complexity of spatial scene ...
- Grid computing of spatial statistics:using the TeraGrid for Gi*(d) analysis
- Wang, S., M. K. Cowles, et al. (2008). Grid computing of spatial statistics: using the TeraGrid forGi* analysis. Concurrency and Computation: Practice and Experience 20(14): 1697-1720. The massive quantities of geographic information that are collected by modern sensing tec ...
- 时空数据智能化处理与分析
- 地球表层系统是一个复杂的巨系统，不仅组成要素繁多，而且各要素间的相互关系复杂，地学分析就是运用系统论、信息论、控制论、高性能计算机、网格计算等现代科学方法和技术手段，综合空间技术和计算技术，揭示地标信息流的地球表层动力学机制与时空特性，反映区域分异和解释区域发展过程。 ...
- HPC in GIS
- The design of parallel GIScience applications is bound to specific conventional parallel computer architectures, such as SIMD(single instruction stream and multiple data streams) and MIMD(multiple instruction streams and multiple data streams) systems (Flynn 1966). This tight-coupleing approach is p ...
- Research note of Experiment in migration by computer
- The areas between migration, or other movement, occurs are connected by a band whose width represents the quantity moved. 1)Ideally a desirable parsing strategy is one which yields only a linear growth in the number of movements needing to shown. Wherei the geographical space is considered t ...
