Explain the integration and development trend of security and GIS technology

The introduction of GIS in the security field is not accidental. There are many links between the two. Their combination will greatly promote the development of the security industry. At the same time, it is also a good complement and perfection for GIS itself. Some of the relevant binding points between the two are analyzed as follows.

Target Geographic Information and Map Data Management

Geographical information refers to the integration of time-space-related goals in the security field in accordance with the basic form of geographic information, the formation of GIS map elements containing graphical objects and attributes, and integration into the spatial database in the form of data layers for unified management. The system basemap may contain one or more security domain-specific business layers. The layer contains a series of elements. One element represents a target and is composed of a graphic object and a property record. The graphic object usually consists of basic points (such as Camera), line (such as vehicle running track), surface (such as a monitoring cell), attribute table stores auxiliary information of the target (such as camera number, name, type, and other attributes, etc.), graphic object and attribute table record Lines are associated by a unique identification number to allow mutual investigation of spatial information and attribute tables.

With the deepening and expansion of GIS applications, in order to better promote the application and development of the industry, industry application standardization will become a necessity.

Emergency Decision Command and Geographical Mathematical Model

Emergency decision-making command generally means that when an emergency occurs, the related responsible department of the incident needs to quickly summarize the information and comprehensively evaluate the decision to guide a series of reaction actions and eventually solve the incident with the best solution. GIS, with its unique spatial-temporal visualization advantages, combined with perfect support for various complex geographical mathematical models, can achieve assisted decision-making applications in a variety of complex situations.

By introducing more scientific and reliable decision models, more effective and intelligent decision support can be achieved.

Video query and virtual reality

Video query is one of the basic functions of the monitoring platform, and it is also one of the most important functions. Here it is divided into real-time video query and video query. The purpose of the query is to locate as accurately as possible. Most of the time we look at real-time video to see if a place is normal (such as a corner), but the vast majority of current video surveillance platforms view real-time video without the query function, or Only simple queries based on attributes such as device names do not implement true spatial location-oriented precision queries. The use of virtual reality technology to build a 3D model of the monitoring target area, the user selection area into the 3D model for query operations, you can find related equipment, the same reason can be used for video inquiries, just add time conditions. Obviously, this search mode is more intuitive and more accurate. The introduction of virtual reality will give users a more intuitive and easier-to-use application experience.

Mobile Monitoring and Mobile GIS

Mobile target monitoring refers to the use of a centralized monitoring platform to manage and monitor a group of mobile targets with positioning device terminals. There are two main points, one is that the monitored target needs to carry the terminal of the positioning device, the other is that there is a monitoring center, and the monitored target reports the positioning information and status to the monitoring center through the wireless network. If the mobile GIS platform is configured on the monitored moving target at the same time, the moving target can have the GIS data collection, storage, and display capabilities, which can completely change the monitoring mode of the monitoring center and the passive monitoring of the moving target. This is in some scenarios. It is very important. If the network environment is unstable, the location information transmitted by the mobile target may be lost, resulting in incomplete location data stored by the monitoring center. In this case, the data stored in the mobile GIS carried by the mobile target may be used to complete the location information. The mobile GIS can also be used to visually display certain instructions issued by the monitoring center to the moving target.

With the development of the mobile Internet era, the trend of mobilization and networking has become obvious.

Cloud Video Surveillance Service and Cloud GIS

With the rise of cloud computing technology, people have initially felt its charm. For a considerable number of application scenarios, cloud services have many advantages. First, large-scale operators provide infrastructure so that the application side can save a large number of physical construction costs and maintenance costs. Second, the cost of using cloud services is lower than that of desktop applications alone, or less upfront investment and fixed monthly operating expenses. In addition, the application of cloud service deployment is more convenient in terms of upgrade and maintenance.

Currently, cloud video services are in operation. Utilizing the scaled hardware resources of cloud services and centralized and unified software technology support, the front-end video capture devices and back-end storage devices are unified and integrated and managed in a cloud service. To achieve cloud video surveillance services. Cloud GIS deploys GIS data and tools in cloud services and provides them to users.

The security monitoring application in the new period needs the support of GIS. Therefore, security monitoring to the “cloud” requires cloud GIS.
