Based on the Vector Topographic Map of the Road Paper Alignment Automation Technique

In view of the traditional paper location methods is low efficiency and restricting highway multiple selection problem,the road design,work outside the industry are analyzed,the research on vector topographic map of constructing digital terrain model of DTM method,proposes the application of latitude road CAD software module DTM function realization of desktop computer alignment automation technology.The application results show that: this technology can realize the data acquisition,route design,graphics design,scheme optimization integration,shorten the design cycle,road survey,improve design quality.
