高精度地形图的 Matlab 与 GMT 联合开发研究
Combined Use of Matlab and GMT Software to Draw High-accuracy Topographic Maps
摘要
Abstract
The digital elevation model (DEM ) is a new technology ,which developed rapidly in re‐cent 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 geo‐morphological 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 .GM T is an out‐standing 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 re‐search 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 GM T problems , such as GM T Chinese characters display function realization ,special data input ,and GM T inter‐face visual operation .In this paper ,we choose Matlab for visualization of GM T data processing and the command input to separate the GM T from the text command pattern and achieve simple operation and flexible application .This approach offers very important applications for many geo‐logical researchers and can help the users to improve the ability to display high‐quality research results .关键词
