Abstract

A data update method and device, the method comprising: map matching the data on a GPS to obtain failed GPS map matching data (101); obtaining a GPS data cluster group (102) that reflects the road shapes from the failed GPS map matching data; and updating the GPS data cluster group to the electronic navigation map (103). The data update method and device relate to data processing technology and can quickly update the data of the electronic navigation map.

Description

technical field [0001] The invention relates to data processing technology, in particular to a data update method and device. Background technique [0002] Global Positioning System (Global Positioning System, GPS) satellite navigation and GPS location service are more and more favored by people, and people have higher and higher quality requirements for GPS satellite navigation and GPS location service. As the core component of GPS satellite navigation and GPS location services, people's requirements for the current situation and fineness of navigation electronic maps are also gradually increasing. [0003] At present, the main process of updating the data of the navigation electronic map is field data collection. The existing field data collection method is: use a geographic data collection vehicle to drive in the streets and alleys in the geographical area, and collect and verify data on all roads in the geographical area. [0004] When using the existing field data col...
