Problems solved by technology

However, this method is relatively cumbersome when the remote sensing data is stored in the database. Both uploading files and entering data information require more manual participation, which is time-consuming and error-prone.

Embodiment

[0028] The first step is to select a piece of remote sensing data (including remote sensing data, metadata XML, thumbnails, etc.) as test data, put the data into the monitoring folder, and the data monitoring module will immediately detect this new data into the monitoring folder ;

[0029] In the second step, the data content analysis module parses and reads the metadata XML file in the test data. The content and description of the metadata XML file are as follows:

[0030]

Abstract

The invention discloses an automatic monitored storage method of remote sensing data products based on a file transfer protocol (FTP) and an extensible markup language (XML). The automatic monitored storage method is used for replacing an ordinary manual storage method of the remote sensing data products, can achieve remote automatic monitoring discovering of the remote sensing data products, data content analyzing and data storing and reduces steps for manual processing and time compared with a manual storage method. NET, FTP, XML and other technologies are adopted as a basis for achieving automatic data monitoring and storage, five functional modules including a data monitoring module, a data content analyzing module, an FTP transferring module, a data information storage module and a journal recording module work synergistically to achieve automatic monitoring and storage of remote sensing data. The automatic monitored storage method of remote sensing data products based on the FTP and the XML is easy to achieve, effectively manages storage of the remote sensing data products, adopts computers for automatic processing in main processes, is less in man-machine interaction, improves work efficiency and is wide in application prospects in the field of remote sensing data products storage management.

Description

technical field [0001] The invention belongs to the technical field of remote sensing data management. In particular, it relates to a remote sensing data product automatic monitoring storage method based on FTP and XML. Background technique [0002] File Transfer Protocol (FileTransferProtocol, FTP) enables the sharing of files between hosts. FTP uses TCP to generate a virtual connection for control information, and then generates a separate TCP connection for data transfer. Control connections use a TELNET-like protocol to exchange commands and messages between hosts. The file transfer protocol is a protocol for transferring files between two computers on the TCP / IP network. FTP is one of the earliest protocols used on the TCP / IP network and the Internet, and it belongs to the application layer of the network protocol group. The FTP client can issue commands to the server to download files, upload files, create or change directories on the server. [0003] Extensible Ma...
