【Abstract】 Name automated placement involved in many factors, such as name parameters, the precedence level of features, the relation between name and symbols, the overlap checking of name and feature and automated decision of name size. The parameters of name, symbols and feature precedence level can be stored in tables of relation database respectively. There are proposed two methods of overlap checking, one is real overlap of names, another is virtual overlap of names in this paper. For the compute efficiency of raster data, both methods are based on the raster data. We also present the algorithm for name placement of line feature based on raster data and the flow charts of algorithms. Finally we introduce a software of name automated placement "AutoLabel".更多还原
