Embodiment Construction

[0049] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. It should be understood that the embodiments described below by referring to the figures are exemplary only for explaining the present invention, and should not be construed as limiting the present invention.

[0050] Please refer to Figure 1 to Figure 10 .

[0051] 1) Upload the data to be loaded

[0052] The existing data types are original geometric data, data after coordinate compression, and binary data. The original geometric data represents the position of each point in x, y coordinates, and the data after coordinate compression represents the coordinates of the intermediate point in incremental coordinates from the starting point. , the binary data is to express the coordi...

Abstract

The invention relates to the technical field of big data visualization, in particular to a geographic big data visualization method and system based on progressive transmission increment drawing, andis characterized in that the method sequentially comprises the following steps of S1 transmitting to-be-loaded data; S2 adding a hierarchical label to the data; S3 loading data; S4 analyzing the data;S5 performing data increment drawing; and S6 carrying out the incremental drawing when the data is dragged. According to the method and the device, the display fluency when massive big data is dragged is ensured.

Description

technical field [0001] The present invention relates to the technical field of big data visualization, in particular to a geographic big data visualization method and system based on progressive transmission incremental rendering. Background technique [0002] Geographic information visualization is the use of graphics, computer graphics and image processing technology to display and interact with the results and data of geoscience information input, processing, query, analysis and prediction in graphical symbols, icons, text, tables, videos and other visual forms. theories, methods and techniques. In geographic information systems, visualization is based on geographic information science, computer science, cartography, cognitive science, information transmission and geographic information systems, and is dynamically, intuitively and visually represented through computer technology, digital technology, and multimedia technology. , Interpreting, transmitting geospatial infor...
