Problems solved by technology

Create a spatial index for spatial data, and cache strategies for logical structures. The logic of existing data structures can be used to construct new strategies based on business, as well as the consumption of memory and disk space. However, in the face of massive 3D geospatial data, the cost of this solution obviously not acceptable

Abstract

The invention discloses a spatial analysis method and system based on a Beidou grid code and a three-dimensional engine. The method comprises the following steps: encoding geographic spatial data according to the Beidou grid code; loading and rendering the geographic space data by using a three-dimensional engine; according to different accessed three-dimensional engines, rewriting the encoded geographic space data; and uniformly packaging interfaces of different three-dimensional engines to form a uniform map API (Application Program Interface) for externally providing a uniform API interface. According to the method, the Beidou grid code technology is utilized, the three-dimensional geographic space data is lightened, discretized and gridded, meanwhile, efficient association and integration of the three-dimensional data and the space sensing data are achieved on the basis of grid coding, the calculation efficiency of the massive three-dimensional geographic space data can be multiplied, and meanwhile, consumption of redundant memory and disk space is avoided.

Description

technical field [0001] This application relates to the field of spatial analysis, in particular to a method and system for spatial analysis based on Beidou grid code and 3D engine. Background technique [0002] In recent years, with the rise of the wave of smart city construction, spatial information has become the core and foundation of smart city construction due to its important characteristics of time and space, and geospatial information and visualization have played an increasingly important role in it. The software engine of the 3D geographic information platform serves the construction of digital cities. It has a comprehensive geometric model of geographic features, can easily manage multiple types of large-scale geographic feature data, and provides accurate spatial analysis and computing capabilities. However, in the spatial analysis of massive data, the spatial retrieval, analysis, and calculation capabilities provided by the engine are all vector matrices compose...
