地质灾害三维遥感解译成果的自动制图方法

Automatic mapping of the results of 3D remote sensing interpretation of geological disasters

针对三维环境下地质灾害遥感解译成果制图需借助第三方软件,难以自动实现的问题,介绍了基于三维GIS平台iTelluro(网图)的地质灾害遥感解译成果的自动成图方法。以遥感解译专题图制图规范为依据,根据用户选择的比例尺和制图范围,从影像数据库和三维GIS图层中自动获取遥感影像图层、矢量图层、地质地理图层和解译专题图层数据,设置专题地图的渲染样式,并在基于iTelluro的地质灾害三维遥感解译系统上实现了该方法。该方法提高了地质灾害遥感解译成果的制图效率,可及时为地质灾害防治与应急提供信息产品。

As it is difficult to transfer the mapping disasters in 3D virtual environment without third - results of remote sensing from the interpretation of geological party software, this paper introduces a method for automatic mapping of the results from the remote sensing interpretation of geological disasters based on a 3D GIS platform named iTelluro. Based on the mapping specification of the remote sensing interpretation from thematic maps, we can acquire the remote sensing image layers, vector layers, geological and geographic layers and interpretation topic layers from the image database, and then choose 3D GIS layers according to the scale and mapping range, set the rendering styles of the thematic map and finally realize the method in the 3 D remote sensing interpretation system of geological disasters. This method can improve the efficiency of the mapping results from the remote sensing interpretation of geological disasters, and can provide the information products for prevention and control of geological disasters as well as for tackling the emergency event.
