Embodiment approach 1

[0057] see figure 1 , a remote sensing image metadata extraction and sharing system based on grid services, client system 101 1 to 101 N A connection is established with the platform application server 103 through the Internet 102 . client system 101 1 to 101 N Communicate with the platform application server 103 to process or access remote sensing image metadata. Client system after installing the plug-in 101 1 Archiving of remote sensing image files is also possible. The client system generates instructions for processing and querying remote sensing image metadata. The platform application server 103 communicates with one or more departmental application servers 105 through the Internet 104 1 to 105 N establish connection. When executing the extraction, archiving, and querying instructions from the client system, the platform application server 103 will analyze the parameter information contained in these instructions, and then access one or more departmental applic...

Abstract

The invention discloses a grid service-based remote sensing image extraction and sharing system and a grid service-based remote sensing image extraction and sharing method. The system comprises a client system, a platform application server, a department application server, a metadata server, a remote sensing image data server, a metadata proxy service module, a grid service management module, a metadata extraction service module, a metadata management service module, a metadata archiving service module and a metadata query service module. The method comprises the following steps of: extracting metadata of a remote sensing image according to the type of the remote sensing image; specifying a remote sensing image catalog for batch processing by a user, batch-processing archived remote sensing image data, and extracting and storing image metadata; and transmitting a metadata query request to the metadata proxy service module by the client system, summarizing and returning an image metadata set which meets each metadata query condition. Through the system and the method, various types of remote sensing image data of the department can be managed, searched and shared.

Description

technical field [0001] The invention relates to the field of remote sensing image management, more specifically, relates to an extensible remote sensing image extraction and sharing system, and a method for extracting and sharing remote sensing images by the system. Background technique [0002] Nowadays, remote sensing technology has developed rapidly, and remote sensing data is becoming an important data source for major scientific research and engineering construction such as urban planning, earth science research, and digital earth. However, with the continuous increase in the amount of remote sensing data and the expansion of application fields, how to scientifically and effectively manage, store, update and reuse existing remote sensing data resources has become a hot spot in the current spatial information metadata research. Metadata refers to data about data, which is specially used to describe a series of information closely related to remote sensing data itself, su...
