| Abstract: | The relation between central meridian & projection plane choice and the distortion value of projection length of areas was discoursed on, and then the essentiality to make use of intrinsic coordinate system was explained. Through coordinate conversion, making use of former data, not only enables the method to satisfy precision requirement and economize capital, and offer lessons from experiment for reference of engineering alike. |
