Abstract

The invention discloses a method for storing and managing massive spatial information data, comprising the steps of: establishing a distributed file system in a master-slave mode, and a storage management node located under the distributed file system for managing the entire life cycle of spatial information data; Under the command control of the management node, the file data is stored in a distributed manner with the file block as the basic unit. It is a distributed storage cluster formed by several data storage nodes and can be horizontally and smoothly expanded. The data storage nodes adopt a distributed storage strategy. The storage strategy is implemented based on the hash modulo algorithm. The invention solves the problem that the existing storage management method cannot effectively store and manage the spatial information data with the characteristics of massive, multi-source, heterogeneous and the like.

Description

technical field [0001] The invention relates to the field of research on storage relationships of massive spatial data, in particular to a storage management method and a storage management system for massive spatial information data. Background technique [0002] Nowadays, the development of satellite technology in China is in full swing, but some areas lack integration of satellite application data information, and there is a serious shortage of overall planning and information fusion. Among them, there are many problems in the storage and management of spatial information data. It tends to be multi-source (space-based, aviation, near space, etc.), and has a huge amount of data. The multi-source of data leads to a huge amount of data, and tens of millions of file data need to be stored; the high-resolution feature makes a single High-scoring spatial information data files (single data) can reach several GB or even tens of GB. It is an inevitable trend to build a storage ma...
