## An Improved Algorithm for Combination of Land-Use Data

• 摘要: 从计算几何的角度提出了一种改进的图斑合并(聚合和融合)方法。图斑聚合采用缓冲区合并的思想,可以有效地合并“桥梁”区域,并保持图斑的自然弯曲形态;图斑融合通过骨架线剖分小图斑,以共享边和地类为共同作用因子,将小图斑逐个合并到原始图斑的拓扑相邻图斑中。此算法有效地维持了图斑边界的自然弯曲,并顾及了图上显示地类的父类整体变化情况。

Abstract: We propose an improved algorithm of combination(aggregation and amalgamation) of parcels on the point of computational geometry.Aggregation is done with the concept of buffer,by which the so-called bridge can be merged efficiently,while amalgamation is done using skeleton.The process of amalgamation is influenced by both the curves shared by parcels and the types of the parcels.After being splitted by skeleton,the chosen parcel derives a set of polygons to be combined by the neighbor parcels one by one.This algorithm keeps the natural shape of parcels,and has taken the amount of the father level of shown parcels into account.
