基于南方cass的土地利用图斑绘制改进方法研究

摘要

The polygon drawing is very important in the second national survey of land use. The paper based on the new standards of urban land use data , studied the deficiency in the traditional method of drawing polygons by southern cass and put forward a line-based method. Using this method, we completed the polygon drawing of a 17 square kilometers area, and it was proved that the method could greatly improve efficiency of polygon drawing and had application value in the second national survey of land use.%第二次全国土地调查中土地利用图斑绘制是十分重要的环节.依据城镇土地利用数据建库的新绘制要求,研究在南方cass下传统的基于面的图斑绘制方法的不足,并提出一种改进的基于线的图斑绘制方法.采用该方法,很快完成了某县城镇17 kmz的土地利用图斑绘制工作.实践证明该方法可以大大提高土地利用图斑绘制的工作效率,确保土地利用数据的质量,具有推广应用的价值.
