摘要
针对GridGIS系统的动态特征、空间数据的复杂特性和专题图层的交互应用等问题,构建了空间集市模型,通过数学工具分析模型中各个性能参数指标的变化情况,并对空间集市模型的相关理论结果,采用实验模拟测试方法进行分析和比较,验证空间集市模型的适用性和灵活性,对真实GridGIS场景具有一定的应用价值。
This paper constructs a spatial load balancing model based on multi-thematic layers in GridGfS, which is named Spatial Market Model, to solve the problems about the dynamic features of GridGIS, the complication of spatial data and interactive applications of thematic layers. It uses mathematical methods to analyze the changing situations of the parameters of perform- ance in the model, adopts the simulated method to analyze and compare the relative results （in theory） of the model. Experiments verify the validity and practicability of Spatial Market Model.
