摘　　要：针对大中比例尺地图中的行政界线、地块权属界线的制图综合问题,利用Douglas Peuker算法,提出距离阈值自适应求解算法对图形进行综合;将平差理论应用于综合后图形的处理中,保证图形的综合质量。讨论了面积、长度、固定点、直角/直线条件的建立,结合实例,研究了综合、平差的算法框架与实施步骤。In this Paper,cartography generalization of administration borderlines and land borderlines in large and medium scales maps is studied.Distance threshold self-adaptable method is provided.The maps are generalized using Douglas-Peuker method.In map generalization adjustment theory is applied,through which map generalization quality is guaranteed.Area,distance,fix point,right-angle/straight line adjustment equations are studied and built.Method framework and implement process of generalization and adjustment are studied by examples.
