Xie Yuanli, an associate professor and tutor for graduate at College of Urban and Environmental Science in Northwest University. Now he is the member of Committee on Photogrammetry and Remote Sensing, the 10th council of Chinese Society for Geodesy Photogrammetry and Cartography, executive member of Shaanxi Province Society for Geodesy Photogrammetry and Cartography. He graduated from Wuhan Technical University of Surveying and Mapping with the bachelor’s degree of Photogrammetry and Remote Sensing. Later, he achieved the master degree at Wuhan University with the major of Geographic Information System. From 1992 to 2001, he worked at First Survey and Design Institute of Railways. From 2003 until now, he has been working at Northwest University. His research mainly focuses in the area of Photogrammetry and Remote Sensing, the Scale of Landscape Ecology. And he also teaches the courses like Digital Photogrammetry, Digital Image Processing for Remote Sensing and Geographic Information System. As early as 1995, he started to do application research on Digital Photogrammetry, 3S technology integration and intellectualization of railway survey and design, automatic aerial triangulation aided by airborne GPS. He presided in the following projects: Application and development of HELAVA Digital Photogrammetric System; Application of Digital Photogrammetry in railway; Computer graphic system for farmland graphs of railway subgrade; Application for Zhongyuan oilfield gathering and transportation pipeline management system based on GIS; Application for oil production plat in Shengli oilfield management system based on GIS; Design and 3D visualization of Moon-Globe plan; QuickBird remote sensing image mapping for the planning scheme area of Baoji; Study on dynamic monitoring system of soil erosion based on DEM(project of Natural Science Foundation of Shaanxi province), etc. As one of the key research members, he participated in the study of coordinated development mechanism between major cities area in Northwest and PREE system (NSFC project), environmental remediation and landscape planning for south coast of Yanhe river in Dong Guan of Yan'an (Yan’an city entrust project). The following are the papers published in recent years:
