The invention discloses a method and a system for file completeness verification of remote sensing image data, relating to the field of processing of remote sensing data. The method comprises the steps of: selecting an appropriate data model according to the type of the remote sensing image data; and performing file structure verification, file composition verification, file attribute verification and file name verification in sequence for the remote sensing image data according to the data model. If the remote sensing image data comply with the corresponding verification rules, the remote sensing image data are considered acceptable in the verification; otherwise, the remote sensing image data are considered unacceptable in the verification. By adopting the method and the system for file completeness verification of the remote sensing image data, the data model corresponding to every type of remote sensing image data is created in advance, the corresponding data model is matched automatically during verification for the file structure verification, the file composition verification, the file attribute verification and the file name verification of the remote sensing image data, and the efficiency of verification of the remote sensing image data can be improved significantly.
Description
technical field [0001] The invention relates to the technical field of remote sensing data processing, in particular to a method and system for checking the integrity of remote sensing image data files. Background technique [0002] At present, many units need to use remote sensing image data in their business, but the composition and format of remote sensing image data files of different satellites and sensors vary greatly. Many remote sensing image data are organically composed of various types of files, all of which are indispensable, and only data with complete files and standardized naming can be effectively identified and utilized. Therefore, how to ensure that the image data management platform can It is extremely important to identify and process these complex remote sensing image data in time. [0003] The current common data management software mainly relies on custom development of specified data types to check the completeness of image data files. The developmen...
