Problems solved by technology

But when the scene is switched to a 3D scene, the data format of the thermal value data changes to {x, y, z, value}, the form of the gradient circle cannot be directly applied, and a flat heat map loses height information and cannot be expressed There is no way to describe the thermal value of a certain point in the space, such as the concentration at an altitude of 100 meters and the concentration at an altitude of 50 meters, so it is impossible to compare the effect of a field model in a three-dimensional space visually and intuitively

Abstract

The invention relates to the technical field of big data. The invention provides a three-dimensional field display method based on a GIS system. The method comprises the steps of obtaining multiple data sources, creating a three-dimensional field space based on the plurality of data sources and obtaining all target data points in the three-dimensional field space, calculating the concentration value of each target data point; obtaining a plurality of key target data points from all the target data points, associating a color value for the corresponding key target data point according to the concentration value of each key target data point, rendering all the target data points in the three-dimensional field space according to the plurality of key target data points and the corresponding color values, and then displaying the three-dimensional field. The invention also relates to a blockchain technology, and the target data point is stored in the blockchain. According to the method, theconcentration value of each target data point in the created three-dimensional field space is calculated, different colors are associated with the concentration values of the key target data points, avisual and vivid field model of the three-dimensional field space is displayed for a user, and the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of geographic information systems, in particular to a three-dimensional field display method, device, terminal and storage medium based on a GIS system. Background technique [0002] At present, the concentration display method of the web-side GIS (Geographic Information System) system in the industry is a two-dimensional thermal map, through a series of thermal value data: {x, y, value}, on a plane canvas with the center point outward The method of diffusion draws black and white diffusion circles, and the overlapping parts of the circles are superimposed in grayscale, so that the density can be displayed. When each point in the area obtains a gray value by superposition, a gradient color band is created, and a corresponding color number is obtained according to the gray value. When all pixels are replaced by the corresponding gray value, a binary image is displayed. Dimensional heat map. But when the sce...
