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 (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 ...

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 ...
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 ...
