How does one make sure how comparable maps are? This ebook goals on the idea of spatial similarity family members and its software in automatic map generalization, together with the definitions, type and contours of spatial similarity kin. integrated are also calculation types of spatial similarity kin among arbitrary person gadgets and among arbitrary item teams, and the appliance of the speculation within the automation of the algorithms and techniques in map generalization.

Suppose that A1 and A2 are two objects in the geographic space. Their property sets are C1 and C2, and C1 6¼ Ф and C2 6¼ Ф. If C1\C2 ¼ C\ 6¼ Ф, C\ is called the spatial similarity relations of object A1 and object A2. The definition of spatial similarity degree was also discussed by Yan (2010). Spatial similarity degree is a value between [0, 1]. It is used for evaluating the similarity relations of spatial objects. 1 Definitions of Similarity 21 Based on the two definitions, Yan (2010) presented three deductions: 1.
The domain of geospatial information is particularly rich in this respect due to the varieties in human spatial languages for expressing and communicating spatial information. Naturally, a spatial similarity-based concept named “Semantic Geospatial Web” (SGW) appeared in recent years (Egenhofer 2002; Fonseca and Sheth 2003). SGW is envisioned as a new information retrieval environment that will facilitate meaningful access to geospatial information (Nedas and Egenhofer 2003; Rodrı´guez and Egenhofer 2004).
3. Approach to determining when a map generalization system or a map generalization algorithm should be terminated in the process of map generalization. 12 1 Introduction The three goals of the research are dependent on each other. The fundamental theories of spatial similarity relations are the foundation of the research. The calculation approaches to spatial similarity relations are based on the fundamental theories and are the main body and also the most important and most difficult part of the study.
