摘要
空间联机分析处理技术将GIS与联机分析处理技术OLAP相结合,提供在空间维度上进行不同尺度钻取的解决方案——SOLAP。在SOLAP的基础上,进一步考虑时间维度,设计了雪花模式的案事件时空数据立方体,通过对目标数据的切片、旋转、钻取等操作,分别基于案发地空间维度、案发时间维度和时空多个维度进行分析,探索案事件在时空上的分布规律,并结合二维颜色矩阵图、二维等值区域图、雷达图等图表对分析结果进行可视化展示,为公安机关犯罪预防、警力配置等决策提供技术支持。
Spatio-temporal online analytical processing （SOLAP） is a technology combining geographic information system（GIS） and online analytical processing technology （OLAP）. It provides a solution to support automated drill operations between the spatial levels of a spatial dimension. Based on SOLAP, the spatio-temporal data cube snowflake model of case is designed with further consideration of time dimension. Through target data operations of slice, drill, rotation, explore the temporal and spatial distribution of case, based on the analysis of space dimension, the time dimension, and the muhiple spatio-temporal dimensions. At last the analysis result is presented by two-dimensional color matrix chart, two-dimensional choroplethic map and radar diagram to provide technical support for crime prevention and police force allocation decision.
