Contour generation algorithm of research based on rectangular gridding method of irregular area

摘要

Combining with characteristics of contour, this paper puts forward the contour generation algorithm, which is proposed in the view of the actual problem. The existing literatures are almost for the research in inerratic area. The rectangular gridding method in this paper is for the seeking of contour in Irregular area and it solve the problem of seeking contour in Irregular area. The process contains grids interpolation algorithm of discrete data and the smooth algorithm of contour (Bezier curve fitting). The experimental results show that this algorithm is simple，easy to realize and good feasibility. Also it can seek contour in any Irregular and draw it. The research result has been applied in our project "Geological Disaster Monitoring Platform".
