A geographic information system (GIS) is a system designed to capture, store, manipulate, analyze, manage, and present spatial or geographic data. The acronym GIS is sometimes used for geographic information science (GIScience) to refer to the academic discipline that studies geographic information systems and is a large domain within the broader academic discipline of geoinformatics. What goes beyond a GIS is a spatial data infrastructure, a concept that has no such restrictive boundaries.
National Geographical Organization (NGO) was founded in 1921 and started its main activities in the filed of geomatic services .
NGO successfully has executed both national and international important projects all over the world and at the present time covers a wide variety of services as follows:
1- Producing coverage topography maps in all scales.
2- Producing urban large scale maps (1/500,1/1000,1/2000).
3- Producing Operational Navigation Chart (ONC) and Tactical Pilotage Chart (TPC) .
4- Producing digital hydrographic charts which are known as Electronic Navigation Charts (ENC) .
5- Aerial photography with large format digital camera .
6- Direct receiving of satellite imagery and image processing.
7- Producing Thematic maps.
8- Technical services related to Border area and border protocols
1-Developing Spatial Data Infrastructure (SDI) in Ministry of Interior and Communication
2-Launching fleet management system, collecting and monitoring information
3-Designing and implementing spatial decision support system for strategic routes
4-Desiging and launching spatial information system for Management of Property and Land
5- Locating high potential area using a passive defense point of view
6- Designing and implementing Police spatial information system
Designing and implementing Police spatial information system
The primarily objective of spatial information system is to define and provide a framework for police activities which are performed with the aim of operating this system in various police headquarters. Given the objectives of police department in the areas of urban security, crime surveillance, and the protection of cities, as well as facilitating crisis management, this headquarter needs full knowledge of all its centers throughout the country. Therefore, possessing a system to manage and display spatial and descriptive information of these centers is very important and necessary
GIS is a necessary tool for crime mapping in law enforcement agencies worldwide. Crime mapping is a key component of crime analysis. Satellite images can display important information about criminal activities. The efficiency and the speed of the GIS analysis will increase the capabilities of crime fighting.
