Problems solved by technology

[0004] For the existing spatial data storage, the version management is not sufficient. There is no good support for multiple imports of spatial data to generate multiple versions, but they are managed separately as different spatial data layers; in addition For the addition, modification and deletion of spatial data primitives, it is also necessary to save and backup as a separate incremental version, so that it can be restored at any time
[0005] When choosing version recovery, you should be able to choose a suitable recovery method according to the version type, such as replacing all records for the main version, and using incremental recovery for the version modified by the user record level. The existing geographic information system is not very good. nice to achieve this

Abstract

The invention provides a management method of spatial data version, comprising the following steps: S1, creating a database table of spatial data storage and importing the spatial data; S2, the evolution of the main version of the spatial data, including the import of the new version of the spatial data and the restoration of the original version of the spatial data; S3, branch version evolution of spatial data, including modification and submission of graphic elements or attributes of the current version of the spatial data; S4, the version tree application of the spatial data, and finding the required version spatial data in the version tree. The invention realizes merging and conflict processing of spatial data editing operation. The record-level version incremental backup and recoveryis realized, which improves the efficiency, and the spatial data version is advanced, traced back and fused, which makes the spatial data version management more flexible.

Description

technical field [0001] The invention relates to the technical field of computer software development, in particular to a method for managing spatial data versions. Background technique [0002] The development and application of geographic information systems has led to the continuous growth of spatial data, and the storage and management of massive spatial data has become very important, which is also the bottleneck of the development of geographic information systems. How to design a good spatial data version management model, support multi-version recovery, storage and backup of spatial data change operations, and provide more flexible spatial data editing functions have become problems that need to be solved in geographic information systems. [0003] The storage structure of spatial data has experienced five eras: file system storage, hybrid data storage, relational database storage, object-oriented database storage, and object-relational storage. At present, in terms ...
