What are GIS applications
GIS(Geographic Information Systems) within the last 30 years has made remarkable development, are widely used in resource surveys, environmental assessment, disaster prediction, land management, urban planning, post and telecommunications, transportation, military police, water electricity, public facilities management, agriculture, forestry animal husbandry, statistics, commerce and finance in almost all areas.
The following is a GIS application areas and role within their respective fields
Resource Management
Is mainly used in agriculture and forestry sector to deal with a variety of agricultural and forestry resources (such as land, forests, grasslands) distribution, classification, statistics, graphics and other issues. Mainly “positioning” and “pattern” of two sets of issues.
Resource Configuration
In the city’s various utility services, disaster mitigation in the distribution of goods across the country, energy security, food supply to institutions throughout the configuration, and so on, are resource allocation.GIS in such applications, the goal is to ensure the most rational allocation of resources and maximize the effectiveness of.
Urban Planning and Management
Spatial planning is an important GIS applications, urban planning and management is one of the main content. For example, in a large-scale urban infrastructure construction, how to ensure that the proportion of green space and a reasonable distribution, how to ensure that schools, public facilities, sports facilities, services, facilities, etc. to have the largest coverage (urban resource allocation problem) and so on.
Land Information System and Cadastral Applicaiton
Of land and cadastral management involves the nature of land use changes, changes in contour plots,cadastre-owned power relations have changed, and many other elements, using GIS technology can be efficient, high-quality completion of these tasks.
Environmental Management and Modeling
Regional ecological planning, environmental status quo assessment, environmental impact assessment, pollutant reduction allocation decision support, environment and regional sustainable development, decision support, environmental protection facilities management, environmental planning.
Emergency Response
Able to resolve in the event of floods, war, nuclear accidents and other major natural or man-made disasters, to arrange the best evacuation routes, and equipped with the appropriate transport measures and support facilities.
Application in GeoScience
Terrain analysis, watershed analysis, land use studies, economic geography studies, spatial decision support, spatial statistical analysis, mapping and so can make use of GIS software to complete,Avismaps GIS is a good Geo-Analysis Application Software System.
Business and Marketing
The establishment of commercial facilities to fully consider their market potential. For example, the establishment of large shopping malls shopping centers if you do not take into account the distribution of the other, waiting for the building of the regional distribution and number of the surrounding neighborhood, once completed may not be able to achieve the desired marketing and service side. And sometimes even shopping malls selling varieties and market positioning, must be built-up areas with population structure (age structure, gender composition, educational level), consumption levels, and so considered together. GIS spatial analysis and database functions, you can solve these problems. Real estate development and sales process, also can take advantage of GIS capabilities in decision-making and analysis.
Facilities Management
The city’s above and below ground infrastructure (telecommunications, water supply, road transport, natural gas pipelines, sewage facilities, electricity facilities, etc.) is widely distributed in every corner of the city, and these facilities clearly have a geo-referenced features. Their management, statistics, summary use of GIS can be completed, and can greatly improve efficiency.
Site Selecting Analysis
According to the characteristics of the regional geographical environment, considering the allocation of resources, market potential, traffic conditions, terrain characteristics, environmental impact and other factors, in choosing the best location within the region, is a typical GIS applications, fully embodies the GIS spatial analysis function.
Newwork System Analysis
The establishment of transport networks, underground pipeline network of computer models to study the traffic flow, traffic to deal with emergencies underground pipelines (burst pipes, circuit), etc. emergency. Police and medical aid selection of the best path, vehicle navigation, etc. are all examples of GIS network analysis applications.
Visualization Application
Digital terrain model as a basis for the establishment of city, regional, or large construction projects, a famous scenic spots of the three-dimensional visualization model, multiple angles view, can be widely used in publicity, urban and regional planning, large-scale project management and simulation , tourism and other fields.
Distributed Geographic Information Application
With the network and Internet technology development, running on the Intranet or Internet environments GIS application types, the objective is to achieve a distributed geographic information storage and information sharing, and remote space navigation.
