Product Management Platform Of Gan River Source Ecological Thematic Data Based On High Resolution Remote Sensing

In recent years,although the economic development of our country is remarkable,the environment has also suffered very serious pollution,and the ecology has been greatly destroyed.In this context,both the government and the society begin to pay attention to the problem of environmental governance.In order to better develop the economy,it is imperative to strengthen environmental protection.To this end,we need to further improve the domestic environmental monitoring capacity.At present,the number of points in domestic monitoring stations not only has a small number of problems,but the distribution is not scientific at the same time.Most of them are located in the urban area,so the scope of the monitoring is relatively limited.This makes the research on pollution early warning,monitoring and application,pollutant distance transportation and other aspects of the research are greatly restricted.In recent years,the rapid development of communication and satellite remote sensing technology has made environmental monitoring have a more powerful monitoring tool.However,those who are engaged in environmental monitoring lack professional knowledge of remote sensing,and the number of controlled sources is also increasing.Especially in recent years,domestic remote sensing satellite technology has been progressing,and there is a tendency to replace the same kind of satellite in foreign countries.But at present,it is difficult to avoid many problems in the application of remote sensing data.Facing the above problems,this paper develops an environment detection platform for multi source remote sensing based on the.NET framework platform and the IDL language.The platform integrates data management and processing,environmental monitoring indicators and evaluation functions,and provides important technical support for domestic environmental monitoring.This study involves the following:First,it provides support for high-score remote sensing satellite data.At present,the format of remote sensing data is pluralistic,and the volume of data is large,and new types are constantly emerging.Therefore,encapsulation of data processing function modules to meet more format needs and extract information from a large number of information has become an urgent demand.This platform introduces the combination of metadata,data file and fast view,which can realize the unified processing and management of data.At the same time,the two languages of C# and IDL are used to complete the development of platform program,so that the corresponding advantage of the latter can be better used.In the system development process,encapsulation and plug-in technology is adopted,which can better enhance the scalability of the platform,so that it can better deal with the processing of remote sensing data with multiple sources and huge volumes,and effectively enhance the efficiency of the system.Second,package algorithm module based on plug-in technology.At present,the system code reuse level is low,high maintenance difficulty has not been well solved,this design will package and plug-in technology integration,refinement sub module to maximize the encapsulation of the related algorithms,one can effectively enhance the reusability,maintenance difficulty will be decreased,and system expansion the function has also been enhanced.Third,we set up a comprehensive platform based on high-score remote sensing.Using the above technology and the advantages of the development of Microsoft desktop application system based on IDL and.NET,the development of this integrated loop testing platform is finally completed.The platform can support the parallel processing function and realize the analysis of remote sensing data,so it can effectively improve the speed of the system.The application of the platform is displayed in the heavy metal mining area in South Jiangxi.
