Abstract
Quality control of indoor data process of channel backsilting survey is introduced on the basis of AutoCAD platform and the theoretical results by marine measuring software NetAPI as well as the oceangraphic depth measuring experiences. By studying a series of technologies such as fix-point sampling,triangulation meshes, editing and manipulation(regionalization,cutting,open-window),the high-precision backsilting sections in different periods can be quickly drawn with batches and the backsilting quantities in any area can be calculated accurately. In that case,the backsilting survey results are optimized and higher-quality survey data are obtained.关键词
