基于ArcEngine的灾害地质立体图图切剖面算法设计与实现

灾害地质立体图图切剖面作为立体图三维分析的一个重要部分,是进行地质灾害分析、预测和防治工作的有力工具.切出的二维剖面图与灾害地质立体图相配合,可以清晰地反映出图区内地层、灾害体、构造的空间分布特征,对于认识各种地质体和灾害体赋存的地质条件和时空分布规律,指导地质灾害预测和防治具有重要的意义.本文在前人工作的基础上,采用面向对象的开发方法,以ArcEngine为基础开发平台,利用C#.NET语言、GIS技术,基于基础地质数据,建立地质剖面图的数据模型,探索在ArcGlobe平台支持下的三维区域灾害地质图中实现自动图切剖面的技术与方法,并在QuantyView平台上,实现了方便、快速、准确的对任意地区任意地段地质剖面的自动绘制.

Algorithm design and implementation of transverse cutting profile for the Three dimensional geological hazard maps based on ArcEngine

The transverse cutting profile of three-dimensional geological hazard maps,as an important part of the three-dimensional analysis in three-dimensional geological hazard maps,is a powerful tool for analyzing,forecasting and preventing geological disasters.It can clearly reflect the spatial distribution of stratum,disaster bodies and geological structure in the region for cutting out two-dimensional profiles matched the three-dimensional geological hazard map,which is of great importance for realizing the geological conditions and temporal and spatial distribution where exist various geological bodies and disaster bodies,and directing the prediction and prevention of geological disasters.Based on previous research,this paper established the data models of geological section map and probed the techniques and methods of transverse cutting profile automatically in three-dimensional environment supported by ArcGlobe,adopting object-oriented development methodology and the base development platform ArcEngine,and using C#.NET languages,GIS technology,based on base geological data.At the same time,the automatic drawing for geological transverse cutting profile of any region was conveniently,fast,and accurately implemented in QuantyView software.
