The continuous development of Internet and big database accelerate the data infiltration of constructions in various aspects. Three-dimensional Slope Information System which is based on web has auxiliary decisive significance on both planning slope engineering and constructions. Based on the two modules which are three-dimensional visualization and image processing in digital video surveillance, a slope information system is developed. The main conclusions are shown as follows: Based on UAV photogrammetry technology and the application of both BIM and GIS, three-dimensional visualization and its application can be realized economically. Based on advanced development of PFC3D, digital elevation model MySQL database and BP neural network, the rapid modeling and analysis of complex slope's numerical simulation are realized. Based on video image processing technology, the interaction between landslide movement and three-dimensional visualization are realized.
