Abstract

The invention provides a spatial data intelligent distribution service method based on big data. The invention relates to the field of spatial data distribution service. The method comprises the stepsof user spatial data collection and order information collection. Statistical analysis is carried out on personal information and behaviors of a user, so that user behavior portrait can be performed,a big data technology is used for carrying out user-to-spatial data content similarity calculation on information such as types and resolutions of spatial data ordered by users and carrying out user-to-user similarity calculation on information such as cities and industries where the users ordering the spatial data are located. and spatial data mining and potential user mining which are interested in the user are realized, and the mined spatial data are intelligently pushed to the user. According to the invention, the user information portrait is established according to the differentiated and dynamic demands of different users on the spatial data, so that intelligent analysis, intelligent acquisition, intelligent classification and intelligent distribution for the spatial data demand ofa specific user are realized, and the construction of an intelligent active push service mode of brand new spatial data distribution is facilitated.

Description

technical field [0001] The invention relates to the field of spatial data distribution services, in particular to a big data-based intelligent distribution service method for spatial data. Background technique [0002] At present, the data storage of my country's spatial data, especially remote sensing satellite data, mostly adopts the data storage mode of "database + file system", that is, the remote sensing data catalog is stored and managed by commercial databases, and the remote sensing data data bodies are stored in the file system. When users query and order remote sensing data, they first query the data catalog database in the remote sensing data commercial database, and determine the final required remote sensing data according to the thumbnails and thumbnails in the remote sensing data catalog database; then, based on the finally determined remote sensing data On, the corresponding data entities are obtained from the file system, and distributed to users by the dist...
