Abstract: | ![]() The paper analyses,calculates and research the land area change based on the transformation from independent reference-ellipsoid-centric coordinate system to independent geocentric coordinate system and gauss projection central meridian change when making digital line graphs,and puts forward a speedy arithmetic method to calculate land area after the transformation of coordinate system and validates this method. |
