Crime Space Analysis Application Technology Based on WebGIS
基于WebGIS 的犯罪空间分析应用技术

By analyzing crime spatial data and related criminal theories, we discuss some of classical or new technology and model of crime spatial analysis such as crime hot spot, four-color warning, and string of case analysis. Realize the case of business data visualization by using the address matching technology, and also combines the mapping cutting block and map classification display technology （Tile Cache） with Ajax technology and the powerful WebGIS platform. According to these researches,crime spatial analysis system based on B/S （Brower/Server） model was designed and established. It has been found that the system is an effective and practical tool for the public security department to control social order and fight against crime.
