- Abstract:
-
In this paper,using DEM terrain analysis technology,we 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,we analyzed the landform of the spatial distribution of the eruptive products that were from the eruption of Tianchi volcano in Changbai Mountains sssince 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,by which the spatial distribution of the eruptive products that was uninvolved by predecessors was speculated.These results can provide a remote sensing basis for making the large-scale volcanic geological maps of the Tianchi volcano,in Changbai Mountains,and especially for determining the scope and limits of some Holocene volcanic eruptive products.
