Abstract
This paper introduces the realization algorithm of ocean element curves and profiles on GIS. The algorithm projects the curves and profiles of ocean elements onto the geographic map. It realizes the combination of two-dimensional spatial geographic location, time dimension of curve change and spatial dimension of vertical profile, and displays three-dimensional information on a two-dimensional plane map. It can well express the actual survey data, statistical analysis data, and realize the comprehensive visualization of marine elements. The algorithm is useful in the visualization of ocean data. The algorithm has good application prospects in the visualization display of marine data, quality control of survey data, joint analysis of different elements or disciplines, and scientific research.
