Embodiment Construction
[0051]In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. the embodiment. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0052] The real space is a three-dimensional space. Mountains, rivers, forests, fields, lakes, grasses and seas are a community of life. Three-dimensional support is an inevitable choice for the unified management and comprehensive management of natural resources. With the new layout of the unified management of natural resources, the entire field of natural resources urgently needs t...

The invention provides a spatial data processing method and system and electronic equipment, and the method comprises the steps: carrying out the layering segmentation of original spatial data according to a geographic grid, building corresponding spatial data bodies according to a plurality of layers of grids, carrying out the spatial point location data thinning of each layer of data entity according to an equal data volume method, ensuring that tile masses of all levels are similar, wherein the spatial data volume comprises original spatial data of a corresponding hierarchy; then, uploading a determined spatial data body set of all spatial data bodies to a network server; and when the user side sends a spatial data processing request to the network server side, enabling the network server side to process spatial data volumes of related hierarchies in the spatial data volume set, and perform interactive operations such as real-time three-dimensional drawing, vector element pickup and vector query by adopting a WEBGL engine. According to the method, a spatial data body is adopted to replace a traditional grid tile, and the problem that the traditional three-dimensional grid tile only supports visualization and does not support application is solved.
Description
technical field [0001] The invention relates to the technical field of three-dimensional GIS rendering, in particular to a spatial data processing method, system and electronic equipment. Background technique [0002] The use scenarios of the existing 3D GIS systems include offline and online modes. Thanks to the development of network technology, calling data slices online through the network has become a regular mode of 3D GIS systems. The slicing process is to uniformly convert the original data into static raster tiles. The raster tiles are similar to pre-symbolized pictures. They only support data visualization and do not have application capabilities such as information query, symbol modification, and comprehensive comparison. The usage scenario is single . Contents of the invention [0003] In view of this, the purpose of the present invention is to provide a spatial data processing method, system and electronic equipment, which uses spatial data volumes to replace...
