Foreword

Appendix A, Appendix B, Appendix C, Appendix D, Appendix E, Appendix F, Appendix G, Appendix H, Appendix I, Appendix J, Appendix K, Appendix to this standard

Record L, Appendix M is a normative appendix.

This standard was proposed by the Information and Communication Bureau of the Ministry of Public Security of the People's Republic this standard is under the jurisdiction of the Computer and Information Processing Standardization Technical Committee of the Ministry of Public Security.

This standard was drafted. Kunming Municipal Public Security Bureau Information Management Supervision Detachment, Yunnan Cody Knight Information Technology Co., Ltd., Kunming Yongquanbao an Electronic Technology Co., Ltd.

1 Scope

This standard stipulates in principle the construction process of urban police geographic information system, as well as the construction objectives, methods, contents and the technical requirements are followed to regulate the construction and management of police geographic information systems.

This standard applies to the construction of the whole process of the urban police geographic information system of the public security system.

2 Terms and definitions

The following terms and definitions apply to this standard 2.1 the process of information system construction begins with the formulation of requirements and the formation of concepts, after analysis and demonstration, system design and development, and use and maintenance processes.

Until the end of the system can not meet the user's needs for another round of system construction, the process is called the information system life cycle.

The police GIS is a spatial analysis function and powerful visual performance capability that is unique to GIS technology.

Integrate police data information with spatial information, and monitor the distribution and real-time operation of various police work elements in space.

Analyze its internal linkages, rationally configure and schedule resources, and improve the auxiliary analysis and decision-making of the rapid response and collaborative processing capabilities of various police departments.

Policy and command and dispatch information system.

3 Construction process

The process of information system construction starts from proposing requirements and forming concepts, after analysis and demonstration, system design and development, and use and maintenance processes.

Until the end, the user's needs could not be met and another round of system construction---software upgrade was carried out. This process is generally called the birth of an information system.

Information system lifecycle (informationsystemlifecycle). Police use of geographic information system (policegeographicinformationsystem) as a kind of information system, it also has its life cycle. In accordance with the principles of engineering methods for information system construction, combined with public security applications and geographical information the characteristics of the information system, the life cycle of the police GIS can be divided into nine stages. problem definition stage, feasibility analysis stage, demand score Analysis stage, overall design stage, detailed design, data organization stage, program coding stage, trial operation and review and acceptance stage, operation and maintenance stage.
