摘要: 分别于2008年10月、2009年10月和2011年7月对鄱阳湖地区开展三个航次的科学调查,在分析实测数据基础上,利用TSM浓度应用HJ卫星CCD传感器数据,提出一种TSMI遥感反演的新方法,并与传统基于实测光谱与TSM浓度建立的方法对比分析,模型反演平均相对误差分别为17.5%和20.01%。实验结果显示,利用TSMI指数方法反演结果较优,不仅可以提高TSM浓度遥感反演精度,而且有利于解决内陆浑浊水体遥感监测中水色大气校正算法研究不足的问题。

Abstract: To solve the problem of 3D real-time visual design for roads,a method based on road template was realized based on lateral and lengthwise structures and the geographic environment of the road.Combining real-time interactive data and the template,the method dynamically creates a 3D road model adapted to the terrain and complying with road engineering and technical standards mutually.An application built on the Gaea Explorer,a 3D-GIS platform demonstrates the feasibility of the proposed method.
