Spatial data management method and system in cloud computing environment

Abstract

The invention discloses a spatial data management method and system in a cloud computing environment, and the method comprises the following steps: (1) designing the concept and specification of a spatio-temporal data asset directory: A, a spatio-temporal data asset item (Item): Item is a core atomic unit and represents that a single spatio-temporal asset serves as a GeoJSON function, date, time and link; the Item is expressed in a JSON format and is very flexible, and a user can customize other fields except the required field according to own requirements; and B, a spatio-temporal data assetdirectory (Catalog) is a simple and flexible self-linked JSON file. According to the method provided by the invention, quick retrieval and data use can be realized in the process from storage to utilization of the geospatial data under the current large data volume, and the utilization efficiency of the resource data can be improved; according to the method, the effect that once data is producedand it can be used by everyone can be achieved; according to the invention, the resource waste phenomenon of repeated storage is reduced, and a solid foundation is laid for subsequent more big data applications. The method conforms to the idea of current data governance.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a spatial data management method and system in a cloud computing environment. Background technique [0002] At present, with the continuous and rapid development of the geographic information technology industry, geospatial data has become more and more important to people's life and production. However, due to the particularity of geospatial data, it is difficult to effectively use different types of data in different business scenarios. Form a unified management mode, such as raster data of remote sensing images, vector data used for engineering surveys, etc. It is the complexity of spatial data that makes it often only possible to target a single business in the process of data search and query Scenarios, more comprehensive data cannot be indexed, and there will be confusion in resource management during the storage of spatial data, and there will be no reasonable and eff...

Problems solved by technology

[0003] The purpose of the present invention is to provide a spatial data management method and system in a cloud computing environment, which has the advantage of being easy to use, and solves the problem that in the process of searching and querying existing data, it is often only for a single business scenario and cannot be indexed more comprehensively In the storage process of spatial data, there will still be confusion in resource management, and the problem of not being used reasonably and effectively
