| description | The invention discloses a geographic coordinate conversion method and device of dwg data, computer equipment and a medium, the geographic coordinate conversion method of the dwg data in one embodiment comprises the steps that the dwg data is acquired, and points in the dwg data have coordinates in a rectangular coordinate system; acquiring a reference point in the dwg data and acquiring a coordinate of the reference point in a geographic space coordinate system; according to the position relation between other points in the dwg file and the datum point and the relation between unit longitude and unit latitude, the coordinates of the other points in the dwg data in the geographic space system are calculated, and conversion is completed. According to the geographic coordinate conversion method provided by the invention, conversion is completed by utilizing the relationship between the unit longitude and the unit latitude on the basis of the reference point, so that the accuracy of data conversion is improved.
