| Abstract: | To the small-scale map in ocean field,the traditional measurement method computes the lengths and areas with a relatively coarse precision.In order to improve the measurement precision,a new method has been provided in this study,which uses ArcEngine technology to finish the conversion between different projections and measure the earth's length,area as well as other information precisely.The different projections,such as WGS1984,Mercator,Lambert and Albers,also have been discussed,which can provide a good ... |
