Abstract

Abstract: In detecting hidden dangers of dyke, the configuration of survey line is ineffective, and the interpretation result of 2D images could hardly describe hidden dangers or anomalies effectively. In view of this, the 3D model of dyke segment and the 3D terrain model around the dyke are established based on the 3D geographic information service platform. The geophysical prospecting database for hidden dangers of dyke is established, and a detection and analysis system is developed. Moreover, the data interface, database storage and 4D visualization expression of geophysical prospecting results are developed. In conclusion, the 4D visualization expression, dynamic analysis and management of time-lapse dyke detection results are realized.

Key words: hidden danger of dyke, geophysical detecting, GIS, 4D visualization, early-warning of danger
