Abstract

An embodiment of the invention provides a method and device for displaying massive points in an electronic map. The method includes receiving point location data of each interest point in the target massive points, wherein the point location data at least includes latitude and longitude information; obtaining target document coordinates of each interest point in a target page document of the electronic map according to the latitude and longitude information of each interest point in the target massive points; adjusting the first size and first document coordinates of a pre-created Canvas element to make the Canvas element and a map container of the electronic map coincide; utilizing the Canvas element to draw each interest point in the target massive points on a layer of the Canvas elementaccording to the target document coordinates of each interest point to be displayed as the target massive points in the electronic map. By means of the technical scheme, all the interest points focused in the massive points can be displayed, and the performance of a browser can be improved.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a method and device for displaying massive points in an electronic map. Background technique [0002] At present, WebGIS (Network Geographic Information System) has been widely used, covering almost all fields including transportation, regional planning, military technical investigation, commercial finance, electric power and water conservancy, etc.; and its application methods are also diverse, including Geolocation, route planning, location query, real-time display, real-time traffic, etc. [0003] In some application scenarios, such as the background monitoring system of shared bicycles, it is necessary to monitor a large number of shared bicycles in real time, so it is necessary to display the abstract points of interest of all shared bicycles in the electronic map; another example is some LBS (Location Based Service , location-based service) system, it is necessary to ...
