| Abstract: | With the improvement in location precision of GPS-RTK,the distance of data transmission and with the enhancement of its dependability,the application of GPS-RTK technology with depthometer in the fields of topographical measurement under ocean,lake,river,and channel measurement is more and more important.This paper discusses the characteristic of layout of control net work and data collection in topographical measurement under water.And then details the method of coordinate transform in measurement by using GPS-RTK technology,including model of 7 parameter transform and 3 parameter transform.Finally,the paper emphasizes the acquirement about height abnormity and the method of height transform. |
