The embodiment of the application discloses a display method and device of the cannon check points on a three dimensional earth surface. The method comprises the steps of mapping the three dimensionalearth surface data into a two dimensional earth surface texture image, wherein the data points in the three dimensional earth surface data is in one-to-one correspondence with the pixel points in thetwo dimensional earth surface texture image, the pixel pints in the two dimensional earth surface texture image comprise the plane coordinates and the color components, the plane coordinates of the pixel points are determined according to the plane coordinates of the data points corresponding to the pixel pints, and the color components of the pixel points are determined according to the elevations of the data points corresponding to the pixel pints; determining the elevations of the cannon check points in the cannon check point data based on the color components of the pixel points in the two dimensional earth surface texture image; based on the plane coordinates and the elevations of the cannon check points, displaying the cannon check points in a target earth surface area. According tothe technical scheme provided by the application, the display efficiency of the cannon check points on the three dimensional earth surface can be improved.
