Problems solved by technology

[0009] Aiming at the deficiencies of the prior art, the present invention provides a three-dimensional visual rendering method of geographic big data, which does not need to directly retrieve geographic location data, shortens the time for data storage and pollution, and thus improves the rendering of massive geographic location data Efficiency, solves the problem that due to the large amount of geographical location data in the existing solutions, it takes a certain amount of time to process or store these data. If the amount of data is larger, it will take longer, and the rendering of the data Slow, prone to stuttering

Embodiment Construction

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. 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.

[0028] A three-dimensional visualization rendering method of geographic big data, the specific steps are as follows:

[0029] Step 1: Layer the visible area of ​​the map so that the visible area of ​​the map is divided into at least two levels of data layers. Each data layer is positioned according to its own latitude and longitude coordinates. The representation numbers of each data layer are S1 and S2 , S3...Sn;

[0030] Step 2: Data processing. First analyze and then filt...

Abstract

The invention relates to the technical field of visual rendering, and discloses a geographic big data three-dimensional visual rendering method. The method comprises the following steps: 1, layering a map visual area, so that the map visual area is divided into at least two or more data layers, each data layer is positioned according to own latitude and longitude coordinates, and the representation number of each data layer is S1, S2, S3... Sn; 2, firstly analyzing the data of each data layer and then screening the data; 3, respectively calling out the data of each data layer and loading the data into a data storage unit; and 4, rendering the data corresponding to each data layer in the data storage unit, and rendering each data layer in a one-to-one manner by a data rendering unit. According to the geographic big data three-dimensional visualization rendering method, the data of the geographic position does not need to be directly called, the data storage and pollution time is shortened, and then the rendering efficiency of mass geographic position data is improved.

Description

technical field [0001] The invention relates to the technical field of visual rendering, in particular to a three-dimensional visual rendering method of geographic big data. Background technique [0002] In recent years, with the rapid development of the Internet, more and more geographical location information display applications have adopted the B / S architecture, and browsers have been used as display windows on the display side. When encountering location information that needs to render massive amounts of data at the same time, the browser's natural single-threaded operation characteristics will greatly limit rendering performance, resulting in slow rendering and lag. [0003] Among them, the patent number is CN111192339A, which discloses a rendering method of geographic location data, including the following steps: dividing the visible area of ​​the map into several grids of preset sizes, and creating a canvas for the display layer for each grid; [0004] assigning ea...
