Embodiment Construction

[0083] Certain terms are used, for example, in the description and claims to refer to particular components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. As mentioned throughout the specification and claims, "comprising" is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect. The following descriptions in the specification are preferred implementation modes for implementing the present invention, but the descriptions are for the purpose of illustrating the general principle of the present invention, and a...

Abstract

The invention discloses a method and a device for updating map data, a navigation system and a server. The method comprises: extracting road information with construction attribute identifier from an electronic map, establishing a construction road database; querying and analyzing wheel paths on construction roads; according to analysis on the wheel paths and information of the construction roads, determining whether the construction road achieves a construction dissolving condition, and when the construction road achieves a construction dissolving condition is determined, correspondingly correcting road information in the electronic map, removing the construction attribute identifier on the construction roads, and marking the related roads as conducted and passable. The method and the device realize removing of construction attribute identifiers through big data analysis, on-site acquisition by an acquisition team is not needed, so manual operation cost is reduced. Through a communication network, the data is updated to user terminals in time, so as to ensure freshness of an electronic map.

Description

technical field [0001] The invention relates to the field of electronic maps, in particular to a map data updating method, device, navigation system and server. Background technique [0002] With the rapid development of the mobile Internet, there are more and more applications based on electronic maps, such as meal ordering services and taxi services. Although there are various forms of applications, the most important way of expression is positioning and navigation based on electronic maps. [0003] There are also various forms of application for navigation in electronic maps, such as drivers using electronic maps for self-driving navigation, or business travelers taking public transportation for bus navigation and so on. Before the emergence of electronic maps, people may need paper maps for travel, and because paper maps are inconvenient to carry, most people have to ask for directions to find their destinations. With the widespread application of electronic maps, peop...
