Abstract

The invention discloses a geographic space data loading method and device based on a thinning algorithm and a storage medium, and the method comprises the steps: obtaining to-be-loaded geographic space data, and obtaining curve points conforming to curve characteristics in the to-be-loaded data; deleting the curve points through a thinning algorithm to obtain new geographic space data to be loaded; and loading the new geographic space data to be loaded. According to the method and the device, the data volume of the geographic space data to be loaded is reduced, the storage space is saved, and the processing speed of the data in use is increased.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a geospatial data loading method, device and storage medium based on a thinning algorithm. Background technique [0002] Traditional geospatial data is managed through the GIS platform and published and applied in the form of services. When the map resource source data is huge, the massive data not only takes up a lot of storage space, but also affects the processing speed of the data when it is used. Contents of the invention [0003] The main purpose of the present invention is to provide a geospatial data loading method, device and storage medium based on a thinning algorithm, aiming to solve the above-mentioned technical problems existing in the prior art. [0004] In order to achieve the above object, the present invention provides a geospatial data loading method based on a thinning algorithm, which includes the following steps: [0005] Obtain the geospatial da...
