| Abstract: | Based on the principle of the oblique distance between two points, this paper selects the research data, designs procedure and calculates the difference between the calculated horizontal distance by slope distance and the projection distance to the ellipsoid. Further, the error contour is drawn, and the variation of the horizontal distance error with the variation of the distance between two points and the vertical right angle is studied. |

| Keywords: | slope distance horizontal distance vertical angle contour line |
