The lack of active participation of the police in the urban planning process is one of the problems that the country's police now face, and this itself leads to a series of problems, including inappropriate location of police stations and offices, regardless of the three basic factors of geography, population and crimes. This problem is rooted in the attitude of the top managers of the Naja (Iran’s police force) and the country, while the city is the most important venue for police missions. The purpose of this article is to study the causes of the emergence of this problem, and further provide and mention grounds for police involvement in urban planning, so that a suitable solution can be devised to end this situation.

Once man left his house for the first time in search of food, he needed a way to return home. The marking of rocks in the round trip, the use of coastline and celestial bodies such as the sun, the moon, and the stars were the first solutions that were less accurate and time-consuming. Later, with the development of technology of radio systems, and then the positioning satellites, routing became faster and more precise. The Global Positioning System was first created by the US Army in 1983, with an expense of $ 12 billion, and with launching the first satellite into space. This system has a variety of basic, manual and car models that have higher accuracy and cost, respectively. The system consists of three spatial, ground and user controls. The receivers will compare the time of sending the signal from the satellite with its receiving time and determine from the time difference the receiver's distance from the satellite. It is necessary to receive information from four satellites in order to find 3D coordinates. Availability in all hours of the day, any kind of weather conditions and ease of use are among the benefits of the system. Variants of this system include TRANSIT, GLONASS, SRARFIX and DORIS. System error sources include: user’s calculation errors and decrease in geometric accuracy.

All events, including security and police incidents, are somehow introduced with their geographic position. A commander (or police planner) is forced to make decisions that require knowledge, awareness and information about his environment (Molavi and Farajzadeh, 2001: 126). In other words, environmental decision makers and policy makers, including NAJA, need spatial and geographical information (Ebadi-Nejad, 2003: 121. The results of the research show that there is a significant relationship between the incidence of crime and characteristics of the place of occurrence (Pourahmad, Guidance and Police, 2003: 81), and each crime occurs in a specific place and geographic position. For example, the concentration of crimes in the central part of cities varies with residential districts. In such a situation, the GIS will be fully responsive to the needs of the police, because this system is basically compatible with positional information. In other words, its main task is to make a reference for information.

Geographic Information System (GIS) was introduced for the first time in Canada in the early 1960s, and since then its users increased day by day until it became global in the 1980s.Large institutions, and even small companies whose number of staff do not exceed the number of the two hands’ fingers, have established national or global geographic information systems to be able to provide valuable information and data to public and private departments and companies. In this way, they prevent unnecessary repeat of work during collecting data and digitizing maps.Today, most of the papers in this science reflect the results of field experiments and pay less attention to the principles of this science. As a result, it's often observed that experts are very capable at the advanced stage of science but weak at its fundamental stage.
Unlike most data types that are commonly used in new information systems, geographic data is of particular complexity, since these data should include information about location, probable topological connections and recorded characteristics of certain matters. The topological and spatial aspects of the GIS used in design and mapping, and the means of distinguishing between these systems and a new system are among the information that have applications in various fields such as banking, secondary research, booking of airplane tickets and recording medical cases.
Geographic data are connected to certain points of the earth’s surface based on standard coordinate systems. If the subject under study relates only to a limited area, the coordinate system can be purely local, otherwise it may be a visual network at the national or international level, such as the Mercator Coordinate System, which is confirmed by everyone in the field. Geographic data are often recognized as a geographical example of "topics" and phenomena. All geographic studies use phenomenological concepts such as city, river, flood plain, limits of classes of plant species and soil continuity as the main components of the analysis and synthesis of complex information.
