Problems solved by technology

[0002] At present, the scatter diagrams that show the dynamic distribution of construction machinery are drawn using the geographic information visualization open source library MapV. The MapV plug-in is a plug-in produced by Baidu. Figure 1 With the increase of the number of scatter points representing construction machinery, the rendering page will become very stuck after more than 100,000 scatter points, which will further cause the page to open for a longer time until the browser crashes

Abstract

The invention relates to the technical field of data processing, and particularly relates to a scatter point drawing method and device. The scatter point drawing method comprises the following steps:obtaining geographic coordinates of a plurality of engineering machinery, converting the geographic coordinates into plane coordinates corresponding to a map selected by a user, wherein the plane coordinates comprise a first plane coordinate and a second plane coordinate, and the first plane coordinates represent the engineering machinery in the non-working state, and the second plane coordinatesguarantee the engineering machinery in the working state; and finally, sequentially drawing the first plane coordinates and the second plane coordinates on different layers in a scatter point mode according to preset frequency, and displaying all the layers in an overlapped mode. According to the scheme, the geographic coordinates can be converted into adaptable plane coordinates according to different maps, and the application range is wider, meanwhile, the plane coordinates are rendered according to the preset frequency, and the situation that pictures are jammed due to the fact that the rendering amount is too large is avoided, and the rendering effect is guaranteed.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a method and device for drawing scatter points. Background technique [0002] At present, the scatter diagrams that show the dynamic distribution of construction machinery are drawn using the geographic information visualization open source library MapV. The MapV plug-in is a plug-in produced by Baidu. Figure 1 When used together, and as the number of scatter points representing construction machinery increases, after more than 100,000 scatter points, the rendered page will become very stuck, which will further cause the page to open for a longer time until the browser crashes. Therefore, it is very necessary to provide a new method of drawing scatter points to adapt to different maps while ensuring rendering efficiency. Contents of the invention [0003] The purpose of the present invention is to provide a method for drawing scatter points, so as to adapt to d...
