摘要
根据数学形态学的膨胀及腐蚀原理与方法,结合土地利用现状图特点,设计了适于工程应用的快速综合土地利用现状图斑的技术方法和流程。并以目前难以自动综合的树枝状狭长图斑或桥梁图斑数据为例进行了实验研究,验证了该方法综合土地利用图斑的高效、高质量的特点。
On the basis of the morphological expansion and corrosion principle, we put forward a method and flowprocess in landuse parcels generalization which is suitable to fast engineering application, combining with the general law of map generalization and minimum cartographic area, distances between patches and width of the par cel on landuse map. A typical case study of the difficult part of long and narrow patches proves that it is efficient to obtain the generalization goal using this method.
