岩溶区土壤地球化学调查多要素图层布点及三维导航采样法——以广西平果县为例
Methods of sampling points pre-layout on multi-element layers and 3D navigation for soil geochemical survey in karst area: a case study of Pingguo, Guangxi
摘要
Abstract
The karst area has some special characteristics such as the bead like distribution of peak and depression, the large area of mountains and the interleaving of the positive and negative terrain. In karst area,the location of the sampling points are often not satisfied by the method of"grid center",as it takes a long time to get to the place of sampling points. Thus,new sampling methods were studied. First,ArcGIS software was used to generate grids and grid points,and number them automatically. Secondly, the locations of grid points were adjusted through the superposition /toggle of high resolution remote sensing image,topographic map,geological map, soil type map and so on. Thus the pre-sampling points were generated in Omap PC terminal. Thirdly, the routes of investigation were planned and three-dimensional navigation was carried out in the field by Omap mobile terminal. This set of method fully implements the advantages of multiple GIS softwares,and realizes the transformation of data in the softwares perfectly. To be efficient with high quality and convenient to complete the indoor sampling points pre-layout and field navigation in karst area,this is also of great significance for other field investigation.关键词
