Area Symbol Model for GIS Based on AutoCAD
Area symbol is an import part for GIS area objects, and area symbol model is essential to GIS. The traditional area symbol model widely used in domestic is elaborated in detail, and abnormal status came from the defective model are analyzed. In order to solve the questions, the common ground between AutoCAD hatch model and the existing GIS area model is pursued. And on this basis, an area symbol model for GIS based on array structure is proposed, that could avoid the basic problem of area display by area symbol. Accordingly, some suggestions are put forward for the change of area symbol model.
