The paper proposes a method which applies database and GIS technology on the visual management of LMT data contrary to the shortcomings of traditional information management methods,which integrates survey sounding location with different spatial data sources such as administrative areas information,traffic information,digital elevation and tectonic information.The paper introduces the principle and process of the platform's implement,and also describes the realization of survey points' plane projection and survey line's straight fitting.Application results show that the platform not only effectively manages data in simple and graphical ways,but also provides necessary information for the field production and data's qualitative processing and interpretation.
