摘要
PURPOSE: A geographic information analysis method using invisible depth analysis is provided to compensate the refraction error of the light by the earth radius of curvature and to increase operation speed. CONSTITUTION: A view target point is selected(S100). Depth data of invisible area is calculated based on the line of sight by using a visible analysis algorithm(S110). A visible analysis algorithm uses a digital terrain model. An image is calculated by using the calculated data(S120).
