Design of Dynamic Map Symbol Based on Multi-transform Assembly
-
-
Abstract
Multi-transform assembly is brought forward to design dynamic map symbol.The data structure of key frame,layer,graphic element,geometry and attribute are used to organize the dynamic symbol.The models of change rate are built to implement the dynamic change of symbol attributes,and the expandable 2D Morph transform matrix of graphic elements is provided,and the affine transform is united to implement the dynamic extraction and visualization of symbol
