GIS 中确定面对象与模糊面对象间拓扑关系的描述
DESCRIPTION OF TOPOLOGICAL RELATIONS BETWEEN CERTAIN OBJECTS AND FUZZY OBJECTS IN GIS
摘要
Abstract
Topological relation is the fundamental and most important relation in the study on spatial relations theory and application,and plays an important role in GIS spatial reasoning,artificial intelligence,data mining and other aspects as well.By analysing the evolution process of topological relations between simple area objects,we put forward an approach,which can describe the special topological relations between certain objects and fuzzy objects,and applied it to deducing in detail the meaningful topological relations between certain objects and fuzzy objects.It has verified through experiment that in theory the approach is feasible.Meanwhile,we adopted the hierarchical calculation when determining the topological relations between certain objects and fuzzy objects,this improved calculation speed and was less prone to error.关键词
