摘要
以济源西北部 1∶ 5 0 0 0 0水系沉积物测量和嵩县小南沟金矿区地球化学勘查两个项目为实例 ,总结了 TIN模型在区域化探扫面和矿区化探剖面的辅助制图中的应用特点及需注意的问题 ,着重介绍了数据布局方法和调整 Delaunay三角剖分网技术 ,对在不规则采样区域边界带圈等值线的形状问题 ,首次采用虚设采样点的方法进行处理 。
The application character of TIN model aid mapping in the regional geochemical reconnaissance and geochemical profile survey in mining area and the problem that should be paid attention to is summarized using two projects as the examples, namely 1/50000 stream sediment measurement in northwestern Jiyuan and the geochemical exploration in the gold mine of Xiaonangou, focused on the data arrangement method and the technique of adjusting Delaunay triangle subdividing net. It is the first time to deal with the problem that concerned about the shape of the contour in the boundary area of the irregular sampling region with the nominal sampling spots and received good result.
