| Abstract: | 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. |
