Abstract

The present invention is applicable to the technical field of geographic information, and provides a spatial vector data indexing and query method based on HBase distributed storage. The method includes: establishing a spatial database metatable, and each record in the spatial database metatable corresponds to a spatial vector Data set table; each server node queries the space vector data set table according to the query conditions, and returns the query results to the client. The invention uses the RowKey index composed of partitions, spaces, attributes, object IDs, etc., which can effectively improve the organization of vector space data, thereby avoiding redundant storage of data; at the same time, it also customizes the partition strategy, which can automatically and evenly distribute data to each On the server node, the resource utilization rate of each node of the cluster is relatively balanced; in addition, the present invention also adopts a spatial coding method based on the XZ-Ordering idea, which can effectively solve the problem of line and area elements crossing geographic grids.

Description

technical field [0001] The invention belongs to the technical field of geographic information, and in particular relates to a space vector data index and query method based on HBase distributed storage. Background technique [0002] Spatiotemporal big data is an important part of big data and a basic information resource. With the gradual implementation of the national big data strategy, the data assets of government departments are becoming more and more perfect, which makes the total amount of spatiotemporal big data continue to increase. [0003] Traditional relational databases have been difficult to meet the storage, management and query applications of massive spatiotemporal big data. Therefore, it is urgent to break through the performance bottleneck of relational databases in mass data storage management and retrieval. In recent years, a number of excellent NoSQL (Not Only SQL, not just SQL) distributed databases have emerged in the field of big data storage, the m...
