The invention discloses an electronic map automatic generation method based on engineering line data. The method comprises the following steps: constructing a line geometric model containing a plurality of temporary speed limit server models by taking station in-station information, station interval information and jurisdiction boundary information as elements of the temporary speed limit server models; reading an engineering data table and a field message of the existing engineering line, and processing in combination with the constructed line geometric model; and for the processing result, according to the set longitude and latitude information of the starting point of the existing line and the azimuth angle of each signal point, calculating the longitude and latitude information of each signal point of the main line and the side line to obtain a corresponding electronic map. According to the method, the efficiency of generating the electronic map data is high, manual participation is little, the method is not restricted by field factors, and the method can adapt to the test environment requirements of any line and multiple lines of a train control system simulation test platform based on satellite positioning.
