Abstract


Pipe network is a complex spatial distribution system for a more intuitive understanding within the pipe network structure , this article describes the two - dimensional GIS pipe network map generation algorithm of the pipe network cross-sectional view of a vertical cross-sectional view of the space on the pipeline network topology analysis . This algorithm is based on C # and ArcEngine GIS spatial vector data provided by the three-dimensional coordinates cross-sectional and longitudinal section of pipe network visualization, calculation and output attribute data to profile topology analysis function , but also describes the the pipeline connectivity analysis algorithm to achieve the the space topological analysis of the longitudinal section of pipe network . And last use DWGDirect.net technology according to the section DRAWING country of standard , cross-sectional view and a vertical cross-sectional view is written and saved as DWG files , the application of this method to generate a cross-sectional view of the DWG format can be edited in AutoCAD , GIS AutoCAD interoperability . This paper mainly describes the research background and research status of this topic , describes the purpose and contents of research projects , which include a horizontal longitudinal section analysis module functional design, as well as data types and their characteristics, introduced in the research the use of key technologies, including ArcEngine technology and DWGDirect of . Cross-sectional analysis function algorithm design, including the capture cross section line intersects the coordinates of the point of intersection of the pipeline , the pipeline cross section generation algorithm , a cross-sectional view of the ground line generation algorithm, add text information ; longitudinal section analysis function algorithm design , including access to the starting point and the end point of the algorithm , connectivity analysis algorithms , pipeline longitudinal profile generation algorithm , the pipeline ground and horizontal lines of a longitudinal sectional view generation algorithm , the angle between the longitudinal sectional view of two segments algorithm , as well as a cross - sectional analysis algorithm to achieve the program .
