Abstract

The embodiment of the invention discloses a road network data updating method and device, equipment, a storage medium and a product, and relates to a map technology and a data road network in data processing. The specific implementation scheme is that the method comprises the steps: acquiring a road network updating instruction, wherein the road network updating instruction comprises road network data of an original version and updated road network data; establishing traffic road network data of the original version according to the feature nodes with the physical features in the road network data of the original version, and establishing updated traffic road network data according to the feature nodes with the physical features in the updated road network data; according to the plurality of feature nodes, establishing a mapping relationship between the traffic road network data of the original version and the updated traffic road network data, and taking the updated traffic road network data after the mapping relationship is established as updated target road network data. Therefore, the problem that an existing road network data updating method is large in accumulative error can be solved, and the accumulative error of the road network data is reduced on the basis that the road network data updating efficiency is improved.

Description

technical field [0001] The present disclosure relates to map technology and data road network in data processing, and in particular to a method, device, equipment, storage medium and product for updating road network data. Background technique [0002] In the context of smart transportation, urban traffic management requires a reliable and accurate road network data for positioning and analysis in various geographic information system (Geographic Information System or Geo-Information system, referred to as GIS) scenarios , data exchange and other needs. Due to the rapid update speed of the real road network, the update of grade or grade road network has been unable to meet the refined management and control needs of smart cities. [0003] In order to realize the day-to-day or even faster update operation of the road network data, the prior art generally uses different operators to manually update the road network data according to the update content of the actual road netwo...
