| Abstract: | The formula of calculating correction of distance distortion about Gauss projection in the hydrographic field mapping is proved from the formula about proportion of length in Gauss projection.The rule about the distance distortion changed by latitude and longitude is analyzed.The relationship between the distance distortion and the zone-dividing in Gauss projection is construed.The necessary of calculating correction of distance distortion in the hydrographic field mapping and the possibility of reducing the amount of zone-dividing in Gauss projection on the seashore of China are discussed. |
