MapGIS点状符号共享方法研究

A Sharing Method of MapGIS Point Symbol

地图符号共享是地理信息共享的重要组成,MapGIS地图符号共享的研究能够较好地丰富和完善地理信息共享内容。针对MapGIS点状地图符号模型,研究其数学模型和符号结构,引入面向共享的通用地图符号(OpenMapSymbol,文中缩写为OMS),构建一种从MapGIS点状地图符号到OMS点状地图符号的映射模型。经实验验证,MapGIS点状地图符号能够较好地映射到OMS点状地图符号中,实现了MapGIS点状地图符号到通用地图符号的共享。

Map symbol sharing is an important component of geographic information sharing.A Research on MapGIS symbol sharing can enrich and improve the content of sharing geographic information.Aiming at MapGIS symbol model,this article studied its mathematical model and symbol structure by introducing the shared oriented general map symbol（OpenMapSymbol,abbreviated as OMS）.Finally,it constructed a mapping model from MapGIS punctuated map symbol to OMS symbol.Experiments result showed that MapGIS symbols can be well mapped and shared to OMS symbols.
