Abstract:The digital elevation model(DEM) is a new technology, which developed rapidly in recent years. It is widely applied in the surveying and mapping. Terrain analysis related to elevation using DEM is the main means of tectonic-activity and Neotectonic research. The analysis of geomorphological attributes can effectively provide important information on the geological structure and its evolution. Currently, there are many software applications that can be used to draw DEM topographic map, such as Mapsis, DEM, Global mapper, Arcgis, Surge with Topo Plug-in. In many cases, these applications are used to complete map drawing and data analysis However, these methods are deficient, when referring to new methods and innovative ideas. GMT is an outstanding common drawing software application that is widely used by many customers. It can produce beautiful graphics and has a flexible organization, while offering powerful data processing and analysis capabilities. The user can customize the maps for analysis according to their own research ideas and better display the results. It is a great professional drawing software and the ideal choice for high quality. In recent years, many researchers tried to solve specific GMT problems, such as GMT Chinese characters display function realization, special data input, and GMT interface visual operation. In this paper, we choose Matlab for visualization of GMT data processing and the command input to separate the GMT from the text command pattern and achieve simple operation and flexible application. This approach offers very important applications for many geological researchers and can help the users to improve the ability to display high-quality research results.
