Acquisition Parameters of Stratified Reliefs by Grid DEM Profiles Method on the Upper Minjiang

With the development of neotectonics, quantitative research on stratified reliefsis required whene valuating vertical uplift movement. In order to solve these problems, a system of stratified relief data acquisition method is proposed and tested on the upper Minjiang River, China. In the research zone, the vertical spatial data of stratified relief was acquired by using a unit grid to analyze the distribution of reliefs in the DEM profiles, which are perpendicular to the river. A field survey and DGPS profile verified the availability of this method.
