Police Investigation Command Positioning System Design And Implementation

Use the existing police geographic information system (PGIS) constructionpositioning information management platform. Through the establishment of specialgeographic information database, and carry out the geographic information systemconstruction, and other system integration. Use of the other information system toprovide rich material, make information to play a bigger role, improve informatizationlevel, reduce the cost, and realize the launching and linkage unit resource sharing, thecommander for the occasion requires command, scientific decision-making, and so on,provide powerful basis.But along with the rapid development of modern city, to our country publicsecurity work put forward higher requirements, traditional Web platform managementinformation and ideas already can not meet the current needs, especially for the publicsecurity reconnaissance command position needs. Police investigation commandpositioning system in the Android platform development, analysis and realize the policereconnaissance command positioning the core of the system function modules,including map module, directory services, path search, geocoding, reverse geocoding,estimating, scheduling, and early warning. For a line police officer directly provide allkinds of position information, make the information real-time change get greatlyimprove.The thesis first of all the key technology are analyzed and introduced, mainlyintroduced how to realize the function of each child function module, and finally theconclusion of the thesis design system was summarized.Through the continuous commissioning and perfect, the police investigationcommand positioning system can start in the reality for use, and other security systemcombination effect is better. In China some economic development fast cities havebegun to develop and use the police investigation command positioning system toquickly solve crimes, after use, reaction the result that come out, the effect is very good.
