## **摘要**

本数据集由生物区域评估计划（Bioregional Assessment Programme）为制图目的创建，未源自任何原始数据集，其元数据由该计划编制。

本数据集为地图产品GAL_112配套的制图掩膜，用于实现清晰标注，并遮蔽报告地图中的冗余要素。

## **数据集历史**

先期创建了一个形状文件（shapefile），用于对数据进行掩膜以突出显示文本内容。

## **方法**

* 创建一个空的多边形形状文件（polygon shapefile）；
* 在ArcMap编辑会话中，通过描绘文本周边的多边形来填充该形状文件；
* 随后使用ArcMAP的高级绘图选项（Advanced Drawing Option）对文本后方的数据进行掩膜处理。
