Rendering method, device and computer-readable storage medium based on rectangular grid

Abstract

The embodiment of the invention discloses a rendering method and device based on a rectangular grid, and a computer readable storage medium. The method comprises the following steps that: obtaining aplanimetric map to determine a datum point coordinate; according to the datum point coordinate, obtaining an alternating graph, wherein a plurality of hexagons in the horizontal direction of the alternating graph are arranged in sequence, and a plurality of hexagons in the longitudinal direction are subjected to interveined arrangement; according to the area of the alternating graph and the area of a preset target rectangle, obtaining a target map, wherein the target map comprises a plurality of rectangular grids subjected to grid code processing; obtaining the center point of the target map and the rectangular codes of the plurality of rectangular grids; according to the center point and the rectangular codes, carrying out position analysis on the plurality of rectangles in the target mapto obtain an analysis result; and according to the analysis result, carrying out rendering. The embodiment of the invention provides a data aggregation way based on the rectangle. The data aggregation way is simple, and a calculated amount is reduced so as to be favorable for subsequent rendering display.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a rendering method, device and computer-readable storage medium based on a rectangular grid. Background technique [0002] At present, in many geographic information system (Geographic Information System, GIS) applications, it is necessary to realize the GIS rendering of the distribution of a large number of information points. Before GIS rendering, data aggregation processing is required. The existing data pooling methods mainly include triangle pooling, parallelogram pooling and hexagonal pooling. Since the shapes of triangles and parallelograms are not similar to circles and squares, but the shapes of hexagons are closer to circles, and the coverage mechanism of hexagons and mobile base station signal cells is consistent, so hexagonal aggregation is mostly used at present. [0003] However, the circles obtained after the hexagons converge are arranged ob...

Problems solved by technology

[0003] However, the circles obtained after the hexagons converge are arranged obliquely, such as figure 1 As shown, it is not conducive to subsequent rendering and display, and this kind of aggregation method is complicated and requires a large amount of calculation
