Cartographic accuracy control for inland electronic navigation chart
Kun Bai · Journal of Dalian Maritime University · 2010
A data processing flow of inland electronic navigation chart was proposed based on IHO S-57 standard to improve the cartographic accuracy according to the inland data source characteristics.Some measures were adopted by establishing readability CAD layer control mechanism,floating point conversion model and conversion algorithm between regional coordinates to improve cartographic accuracy.Tests show that the proposed measures can effectively control the cartographic accuracy.
