The Design and Application of Automatic Detection and Correction System on Spatial Conflict to Line Object Based on DWGDirect

摘要

This problem considered in this paper is the fully automatic spatial conflict detection and correction. In this work we discussed the implementation idea to spatial conflict detection and correction system based on DWGDirect by taking the conflict between contours and river lines for an example: at first we use the DWGDirect to get the data form digital map, position the conflict areas in rapid intersection algorithm, and conformably correct the contours by vector transformation. Experimental results show that it is practicable and meets the actual requirements.
