Problems solved by technology

[0004] However, when the positions of stations and equipment along the railway line change, they cannot be reflected in the GIS map. In the process of using the GIS map, when the geographical coordinates of each station and equipment cannot be updated in real time, errors occur and affect the railway normal operation of

Abstract

The invention discloses a railway GIS map data processing method which comprises the following steps: acquisition target information of a target to be acquired is established, and an acquisition target data file is generated; the trained image target recognition neural network model is utilized to search an acquisition target, the geographic information of the current position of the acquisition target is marked on a GIS map, new geographic information is generated, the new geographic information is compared with the current geographic information, and the geographic information is corrected.According to the scheme, the problem that an existing railway GIS map cannot quickly and accurately update geographic information of stations, equipment and the like along a railway is solved; the GISmap is ensured to be more reliable and accurate in the using process, positioning errors are reduced, the correction result is accurate, and the cost and the working intensity of manually collectinggeographic information on site are reduced.

Description

technical field [0001] The invention relates to the technical field of map data processing, in particular to a method for processing railway GIS map data. Background technique [0002] Geographic Information System (Geographic Information System or Geo-Information system, GIS) is sometimes called "geoscience information system", referred to as GIS map data. A technical system for collecting, storing, managing, computing, analyzing, displaying and describing geographically distributed data in space. [0003] At present, the use of GIS maps in the railway field can realize real-time update and monitoring of equipment coordinates on the map, such as: which line is the on-site personnel, equipment or train located (uplink or downlink), which line of the station The track; which mileage point is the on-site personnel, equipment or train located near; which feature point of the turnout is located by the on-site personnel, equipment or train (basic rail joint, switch before the sw...
