Design and implementation of marine geology 3D Geographic Information System based on Skyline

In order to improve display effect and analysis and decision ability of marine geology information, the Marine Geology 3D Geographic Information System is established based on Skyline software and Visual studio.NET development platform. It is a WebGIS application platform, builds submarine 3D scene by using the satellite image and marine geology survey data, provides 3D scene roaming, attribute query, submarine terrain browsing, sea level rise simulation, coastline change simulation, mineral resources evaluation and other functions, provides service for marine geology survey, development, management, and decision making. This paper mainly introduces the design of system framework, data preparation, and function realization for the purpose of discussing the design and realization of 3D WebGIS based on Skyline.

I. Introduction

With the quick development of global digital technology, 3D (three-dimensional) digital information has gradually become a mainstream application, due to the specific expression and visual advantage [1]. Compared with the traditional 2D (two-dimensional) GIS, 3D GIS application provides better display effect and analysis decision ability. In the expression, 3D GIS can vividly display object and natural phenomena, promote the popularization of GIS. In the spatial analysis, 3D GIS can not only fully integrate 2D spatial analysis functions, but also break the bondage of 2D plane mode. 3D GIS can meet the social service need of spatial information.
