Remote Sensing Information Processing Service



What we can do for our users?

Remote Sensing Information Processing is our data-based application service for customers in remote sensing applications. Users can entrust us with the processing of complex remote sensing information, and at the same time, they can also assist users in assisting remote sensing applications.


We are doing

We are striving to build an integrated space-to-land remote sensing platform and "remote sensing +" technological innovation, continuously expand the application of remote sensing data, deepen the value of remote sensing data, research and establish application models, combining aerospace and remote sensing, the Internet, big data and cloud computing, in geology Prospecting, precision agriculture, environmental monitoring, watershed management, disaster prevention and reduction, government informatization, and industrial informatization provide intelligent decision support.


Serving the country's land, urban planning, urban construction, forestry, agriculture, transportation, electricity, water conservancy, mining, oil, natural gas, archeology, environmental and other industries


Service area


We are committed to the country’s important mineral energy supply. We use the “Remote Sensing + Address” professional technology approach to guide our country’s major mineral energy supply, and extensively develop coal, multi-metal, oil and gas resources, natural gas hydrates, coal bed methane, remote sensing geological surveys and evaluations. It has undertaken a large number of basic geological surveys such as regional geological surveys, remote sensing geological surveys, and mineral resources exploration and evaluation. It has profound historical accumulation and technological leadership, and has made positive contributions to safeguarding the country’s strategic energy supply.



Geological prospecting


In recent years, we have carried out regional geological surveys and mineral geological surveys and other projects in China's Yili, Western Kunlun, Weihe, Qinghai Province, and Dachaidan. The district completed 19 adjustments of mining results and accumulated rich experience and valuable information.




Regional geological survey



Resource remote sensing


According to the remote sensing spectrum analysis, the micro-permeability extraction and analysis of hydrocarbons are carried out, providing technical references and direct basis for the delineation of oil and gas reservoirs.

The remote sensing data was used to invert the distribution of frozen soil thickness, extract information of hydrocarbon micro-altelinealterations, and combined with remote sensing tectonics and comprehensive interpretation of lithologic bottoms to establish a natural gas hydrate prediction model, and then to predict and evaluate hydrocarbon accumulation.

Hydrological remote sensing


Combining the analysis of hydrogeological conditions and groundwater activity, the use of remote sensing data to interpret the distribution of surface water, springs, and rich water areas, analyzed and evaluated the occurrence of groundwater resources, and successively conducted hydrogeological assessments in various regions to provide local socio-economic development. Reasonable use of water resources and provide decision-making basis.


Remote sensing


Using the combination of remote sensing and geoscience techniques to carry out geological interpretation of line engineering, disaster assessment, resource occupancy evaluation, and exclusion of hidden dangers, and provide decision-making reference in the feasibility study stage of the construction of highways, railways, long-distance pipelines, and high-voltage power transmission lines. It has the advantages of high efficiency, high speed, low cost and scientific evaluation. It has been applied in more than one hundred routes, highways and oil and gas pipelines throughout the country.


Hydrological remote sensing



Environmental remote sensing


Remote sensing surveys and monitoring are conducted on major ecological and environmental issues such as natural resources, biodiversity, land desertification, and mine geological environment.

For ten consecutive years, we have undertaken major national projects such as remote sensing survey and monitoring of the ecological environment in the country, and evaluation of the ecological environment of the National Geopark. We have also undertaken a large number of remote sensing interpretation projects for the environmental impact assessment of projects.

Using remote sensing to provide technical services for the harmonious development of man and nature.


Urban environmental monitoring


The use of remote sensing information extraction technology can quickly and accurately obtain urban environmental impact factors, pollution sources and pollution status, and provide monthly decision support for urban protection work.

In 2015, we completed the construction of an environmental monitoring and management system for Xi’an, China, and conducted dynamic remote sensing monitoring of air quality, urban green space, water resources, wetland environment, dust at construction sites, and vehicle exhaust gas in Xi’an, and realized the automatic updating of environmental data and online inquiry. Share in real time.


Enviromental remote sensing



Disaster remote sensing


Using the advantages of rapid data acquisition by remote sensing to provide technical support for emergency rescue, it has played a technical support role in China’s Wenchuanearthquake, Yushuearthquake, Zhouqudebris flow, and Jiuzhaigouearthquake emergency response, and provided remote sensing image data to the disaster area for the first time. Rescue provides a reliable basis.


Disater remote sensing



Based on the research and application of Geographic Information System (GIS), combined with Internet of Things technology, big data and cloud computing platform, to provide intelligent, digital solutions for coal, petroleum, land, planning, transportation, electricity and other industries.


We have developed systems solutions such as smart mining systems, digital watershed management systems, digital oilfield systems, intelligent pipe network systems, etc., which have played a positive role in enhancing enterprise management efficiency, improving operational quality, ensuring safe production, and achieving intelligent management decisions. 


Industry infomatization



Smart energy



In terms of graphic processing, it has undertaken a number of projects such as land and resources surveys, geological disaster investigations, regional geological surveys, geological and mineral prospecting, hydraulic ring geological surveys, and national mineral rights verification, geological survey work deployment, and dynamic evaluation of the entire survey area. Professional image production and output. He has undertaken the digital map production and export of a number of highway engineering geological survey environmental monitoring and evaluation, digital city, three-dimensional GIS and other market projects in different regions of the country, completed the establishment and update of multiple GIS databases, and achieved a number of national technologies Achievement Award.
