Application Of 2D Map Display Technology In Remote Sensing Product Production Order Subsystem

Remote sensing technology is used in all areas of life.Its extensive application has brought the mass production of remote sensing product orders.However,the remote sensing production order itself has the characteristics of related information,which needs the relevant information of the order and the relevant information of the remote sensing data.How to create and manage the production order reasonably and efficiently is the problem to be solved in this thesis.In this project,the production order subsystem of remote sensing products is part of the scientific information product processing subsystem.Scientific information product processing subsystem is a product production project jointly developed by the school of computer and information engineering of Henan university and remote sensing of the Chinese academy of sciences.The remote sensing product order subsystem is mainly used for the interaction between the system and the customer,providing users with services to create and manage production orders.In the basic function subsystem of remote sensing products production orders at the same time,remote sensing products production orders subsystem application the two-dimensional map display technology,bring customers more intuitive,efficient service operation.In this project,I have completed the following two parts:First,design and implement the production order subsystem of remote sensing products.Remote sensing products production orders subsystem to achieve the main features,create production orders(Including the automatic access to satellite data,production time,satellite data over time,regional latitude and longitude,etc),at the same time,the user can also add satellite data files from a local PCS,to complete the order creation;Browse the production order;Modification of uncommitted order;Submit production order and other functions.Second,realize the application of 2d map display technology.The acquisition of image boundary(longitude and latitude)is a function of the production order of remote sensing products.The image boundary is obtained by two methods of two-dimensional map display technology in this project.One is to get the image boundary from the map view.Second,the image boundary is obtained through the urban area linkage.The basic functions of the production order subsystem of remote sensing products have been realized.The application of 2d map display technology in this subsystem makes it easy and easy to create and manage the production order as a whole,which has achieved the desired effect.
