摘要: 根据面状符号的结构特征和实现机制,提出了基于分层的面状地图符号设计方法,把面状符号分为若干层,每层采用一种填充方式,并在基于VC++的Cartosymbol软件中实现。结果表明,该方法既便于地理现象的表达,又便于计算机实现。Abstract: Integrating the structure and the implementation mechanism of the area map symbol, this paper prcsents a model of designing area map symbols in layers. An area map symbol is described in one layer or more layers, and every layer is implemented in a filling pattern to portray one geographic phenomenon. In the software of Cartosymbo, the method is realized.
