In this paper, using DEM terrain analysis technology, the authors acquired a three-dimensional topographic map, which can give prominence to the valley information. By the DEM technology, such as slope analysis, elevation profiles analysis, three-dimensional perspective, the authors analyzed the landform of the spatial distribution of the eruptive products that were from the eruption of Tianchi volcano in Changbai Mountains since Pleistocene. The results were compared with that of the Predecessors’ filed geological survey. The topography features of eruptive products in the study area were summarized.
