Land-use/Land-cover Monitoring

Techniques of remote sensing, geography information system and global positioning system are applied to monitor national region in all weather conditions, to ensure the accuracy, integrity and update of land investigation, land use and land dynamic monitoring, thus achieving effective management of land resource.

Precision Agriculture Management

Agriculture information can be obtained by remote sensing satellite in nearly real-time, including crop categories and growing status, by analyzing remote sensing image data, which provides decision-making support for planting activities, pest control and production increase.

Water Resource Monitoring

Remote sensing technique is widely applied in disasters monitoring, evaluating of floods and drought, investigation of soil erosion, hydraulic engineering plan, ecological environment monitoring and river pollution monitoring. By taking advantages of satellite remote sensing, demands of water conservancy department can be met, which leads to Intelligent water conservancy.

Forestry resources management

With use of remote sensing technology, geographic information system and cloud-computing, datas can be effectively obtained in real-time and be used in daily management (including forest-fire prevention, deforestation, and statistics of forest resources, etc.), to provide technical support for resource monitoring and performance evaluation on ecological project, and to perform macro, dynamic, precise and continuous monitoring on national forestry area in all weather conditions.

Ocean Environmental Monitoring

Marine remote sensing is used to monitoring marine and coastal zones, with technical advantages of multi-temporal, multi-band, fast response and large area coverage. Marine remote sensing can be applied to marine environment and resources investigation, marine fishery dynamic monitoring, marine pollution measurement, marine disaster warning, coastal and island investigation, marine engineering management, marine surveying and mapping and route selection.

Environmental Protection Support

Remote sensing technique plays an important role in monitoring、 managing and control of environment pollution, including water and air pollution, by providing ecological data services to environmental protection administration departments and enterprises
