The invention discloses a surveying and mapping method based on municipal engineering, and relates to the technical field of municipal surveying and mapping, which comprises the following steps: establishing a control network, performing GPS observation calculation, performing elevation control, performing off-line control, performing measurement by using four GPS receivers, selecting a coordinate system, converting the coordinate system into a Gaussian orthographic projection arbitrary band plane rectangular coordinate, and performing mapping. Converting the side length of the Gaussian plane into the side length of the ground, and then carrying out the back calculation of the side length of the ground. According to the surveying and mapping method based on municipal engineering, a coordinate system is selected and converted into any rectangular coordinate with a plane of Gaussian orthographic projection, then the side length of the Gaussian plane is converted into the side length of the ground, and then the
