A method for displaying and correcting bus routes on a map

Abstract

The invention provides a method for displaying and correcting a bus route on a map. The method comprises the following steps: extracting GPS data from a GPS data source in a real-time manner; performing projecting calculation on extracted GPS data for correction; extracting a previous record from a correction database, judging the current direction through the combination of the previous extracted record and the current corrected data, and storing the current data into the correction database for updating; obtaining corrected GPS data from the correction database and displaying the obtained GPS data in a real-time manner by a client-side. According to the invention, the effect of a GPS for route display on a third-party map pack is corrected, and the driving direction of a bus and a previous bus station where the bus passes are computed, so that the precise display of the GPS position data of the bus on a third-party map is realized, accordingly the bus can be displayed on the bus route, and the use experience of a user can be greatly improved; a display terminal is not required to display both the routes of the coming direction and the leaving direction, thereby being more concise; the next route station of the bus can be foreknown, so that people can be reminded before the bus arrives at the station.

Description

technical field [0001] The invention relates to a method for displaying and correcting bus routes on a map, and belongs to the technical field of the Internet. Background technique [0002] In the development of an APP based on real-time positioning of buses, it is necessary to display the latitude and longitude information of the GPS device on the bus on the maps provided by different companies on the APP (Baidu, Kay Rucker, etc.), such as figure 1 Shown, the technology that prior art adopts is: [0003] 1. The server obtains the GPS device information from the cooperative company system each time, and stores it in the server database; [0004] 2. The client regularly obtains the latitude and longitude information of the GPS from the server; [0005] 3. On the third-party map package, the client displays the latest acquired latitude and longitude information on the map. [0006] It can be seen that the disadvantages of the prior art are: because the server obtains the me...

AI Technical Summary

Problems solved by technology

[0006] It can be seen that the disadvantages of the prior art are: because the server obtains the metadata of the GPS device, but the GPS device itself will have GPS errors, and the third-party map package used will also display the same GPS latitude and longitude due to the route errors of different companies. There will be deviations on different maps, which will eventually lead to GPS information not being completely and correctly displayed on the bus route, resulting in poor user experience and failing to achieve the desired effect of the product
