Abstract

The invention relates to the field of spatial data storage, in particular to an SQLite-based spatial data local storage method, a medium and electronic equipment, and is characterized by comprising the following steps: 101, defining a data model: designing a spatial data storage table, and defining the data model; 102, data compression: compressing the target data to reduce the size of a physicalfile; 103, storing the compressed data into an SQLite data storing the compressed data into the SQLite database; 104, performing data inverse solution: performing inverse solution to obtain coordinate values before data compression; 105, spatial query. According to the method, quick migration of the files is facilitated, the stability of the data is ensured, and efficient spatial data storageand accurate spatial query functions are realized.

Description

technical field [0001] The invention relates to the field of spatial data storage, in particular to a SQLite-based local storage method, medium and electronic equipment for spatial data. Background technique [0002] With the large-scale application of many telemetry methods such as remote sensing and aerial survey, a large amount of spatial data with geographic location information is generated. For massive spatial data, how to efficiently store it has become a very important part of the utilization process of spatial data. The traditional spatial data adopts the HDF storage format and the local storage solution of the storage service, which has the following problems: [0003] 1) It is inconvenient for quick migration of files. The registered storage service needs to be installed, and the normal operation of the storage service must be ensured during the migration process; [0004] 2) Data is easily corrupted. Files are easily damaged and cannot be repaired when encoun...
