The Design and Implementation of Roadworks Management System Based on GIS

Most of current construction project management software focus on text, quantity information and lack of engineering graphics, display, query and analysis of features and other spatial features. In order to solve these problems, GIS is taken as the core, Multipatch programming is used in the natural ground and roadbed, drawing 2D features are stretched for 3D visualization and dynamic 3D display of construction progress. The TIN model is constructed and the main spatial analysis functions are implemented, including the query of 3D point information, the query of longitudinal section, cross section, volume, surface area as so on at any position. A road engineering construction management system is developed in Microsoft Visual Studio2010 platform using c # 4.0 language, the GIS secondary development tools ArcGIS Engine9.3 and Microsoft Access2007 database. GIS is taken as the core in basic framework of the system, the system has a certain application prospect in the road construction management.
