| Abstract: | Nowadays,more than 95% of navigational charts are Mercator charts.Mercator chart plays a significant role in navigation.Essentially,chart is a special kind of map.In the paper,based on the mathematics principle of Mercator projection and knowledge of Cartography,the formulation and deformation of Mercator are derived in detail.On this basis,the features of Mercator projection and characteristics and application of Mercator chart are further discussed. |
