摘　　要：为了解决矢量瓦片在线制图过程中遇到的注记标注问题,从矢量瓦片数据和地图样式配置两方面提出了一套处理方法,包括基于分类与分层的注记配置、基于注记优先级的图层顺序配置以及基于注记类型的分类优化配置。通过实验证明运用该方法可以在注记压盖和分布方面优化注记的标注,增强了地图的易读性、美观性与清晰性。In order to solve the problem of label placement encountered in vector tile online drawing,a set of methods are proposed in terms of vector tile data and map style configuration,including the label configuration based on classification and layering,the order of layer configuration based on the priority of label,the optimization according to the feature type of label.Experiment shows that the methods can optimize the label placement in label overlapping and distribution while enhancing the readability,aesthetics and clarity for maps.
