摘要：
Digital Elevation Model has wide applications to drainage networks, topography parameters and hydrological analysis. Because of a variety of reasons, we easily make errors during the process of data collection. However, we can obtain a range to conclude the true value of data by using the correct investigation methods. In this paper, definition system of digital elevation grey model (DEGM) was proposed by using grey operation, and a modified case was to be verified the feasibility of grey model in real applications.
