Map road network fusion updating method and system based on big data mining

Abstract

The invention provides a map road network fusion updating method and system based on big data mining. Dependence on field data surveying and mapping or floating car access by current map road networkupdating can be overcome. The method comprises mining road network updating information from a mining website library according to a preset mining strategy; further automatically performing preliminary screening according to a preset preliminary screening strategy to obtain effective update information, and then sequentially performing road network update information data fine screening arrangement, road network vector and rule attribute data update, road network differential fusion update and map data release update on the effective update information to realize update of the website map. Byadopting the updating method provided by the invention, the opening or updating information of all road networks can be quickly and comprehensively mined through the Internet, and is updated to the map data at the first time after data processing, so that the problem that the current map road network updating depends on field data surveying and mapping or floating car access is solved.

Description

technical field [0001] The invention belongs to the technical field of electronic map road network update, and in particular relates to a map road network fusion update method and system based on big data mining that can overcome the current map road network update's dependence on field data surveying and mapping or floating vehicle access. Background technique [0002] Traditional electronic map updates mostly rely on manual field surveying and mapping, mobile survey vehicles, and remote sensing image collection. After data collection, manual entry is performed in the office. There are problems with long map update cycles, high costs, and heavy workload. When the map is released, the current situation has fallen behind , the road network of the electronic map cannot be updated in time. In recent years, there has been a method of extracting and updating roads using floating vehicle trajectories, but it requires a sufficient amount of access vehicle trajectory data accumulate...
