摘　　要：基于大比例尺地形图的图式要求,本文以几类典型的地形图符号为例,提出并详细论述如何利用SLD进行地形图的渲染展示。从空间数据的服务发布,到GeoServer中图层的符号化配置,根据点线面的不同呈现形态与SLD的渲染规则,分别从基于属性符号化、组合线型表达、整列符号填充这三个方面为例进行阐述,利用多样化的描述性特征,实现合理化的地图表达。Based on the schema requirements of large-scale topographic maps,this paper takes several typical topographic map symbols as examples,proposes and discusses in detail how to use SLD to render topographic maps.From the service publish of spatial data,to the symbolic of layers in GeoServer,according to the different presentation forms of points,polylines and polygons and the rendering rules of SLD,take an example on three aspects:attribute-based symbolization,combined line type expression,and column symbol filling,to illustrate using a variety of descriptive features to achieve a rational map expression.
