Syntactic Characteristics and Smart Construction Mechanism of Thematic Map Symbol

Abstract

Abstract:

The construction for thematic map symbol is a very complex and intelligent process. This symbol can be automatically generated and easily shared on the web through the syntactic structure of semantic symbols. The symbol types, inner structure and its design pattern are expounded. And a syntactic construction theory based on letter (thematic maps primitive) - word (single thematic symbol) - sentence (combined symbols or complex symbols) structure model is put forward for automatic construction of thematic map symbol. Then, a formal description of the mechanism is given and a Object-relational model based design pattern is developed. Finally, A formal description model is proposed based two application systems. The results of this formal description have been applied to integrate application.

Key words: syntax, thematic map, symbol, linguistics, web cartography, construction
