Method and system for improving cross route rendering efficiency

Abstract

The invention discloses a method and a system for improving cross route rendering efficiency, and relates to the field of aviation informatization management. The method comprises the following steps: pre-defining a priority rule; initializing priority values of the routes to enable the priority values of all the routes to be the same, and rendering a plane crossing graph; dividing the plane cross graph into map blocks with preset sizes, respectively detecting the number of cross points contained in each map block, and determining a target map block; and according to a priority rule, adjusting a display priority sequence of the target route in the target map block, and rendering the route into a vertical crossing effect with a hierarchical relationship. The method is suitable for rendering of cross routes, the efficiency and speed of route rendering can be improved, the target route is highlighted, and the impression of multi-route superposition is improved, so that the route viewing efficiency of a user is improved, and strategy planning of a new route is facilitated.

Description

technical field [0001] The invention relates to the field of aviation information management, in particular to a method and system for improving the rendering efficiency of cross-airlines. Background technique [0002] With the increasing development of China's civil aviation technology, the annual civil aviation market turnover amounts to hundreds of billions of yuan, and local governments are still faced with the need to open a large number of new routes every year. At present, in order to provide guidance for the opening of new routes, both local governments and Airlines usually draw the route information of relevant routes on the network map, which is convenient for visual display of route information and strategic planning for new routes. [0003] At present, the way to render the route on the map is usually to directly represent the route with lines and render it directly on the map. When the number of routes is large, there will be a large number of route intersection...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is that when the existing route rendering method is faced with a large number of routes, if the routes are not optimized for rendering, the routes will be intertwined and difficult to distinguish when they are mixed toget
