基于Google Earth数据的Surfer三维地形建模

Surfer 3D Terrain Modeling Based on Google Earth Data

对于资源潜力不明的新勘查区,尤其是地形复杂区,快速获取其地形图或三维地形模型,是开展相关勘查工作的基础.以滇西北茅草坪铜多金属矿区为例,提出了利用Google Earth平台提取研究区的三维空间数据,借助Surfer软件生成等高线和三维曲面模型的一种绘制大比例尺地形图或三维地形模型的直观、便捷方法 .该方法具有低成本、高效、准确的特点,可操作性强,可在当前地质勘查工作中广泛应用.

To the new exploration area with unknown resource potential, especially in complex terrain area, quickly accessing the topographic maps or 3D terrain model, is the basis for conducting exploration work. This paper takes the example of northwest Yunnan Maocaoping copper metal mine proposed study area using Google Earth platform to extract an intuitive and convenient method which makes use of the three-dimensional spatial date,contour and 3D surface models,generated with the Surfer software a draw large-scale topographic maps or 3D terrain model. This method is low-cost, efficient,accurate characteristics,operability, and can be widely used in geological prospecting work.
