Cartographic masks for map products GAL115

## **Abstract** \n\nThis dataset was created within the Bioregional Assessment Programme for cartographic purposes. Data has not been derived from any source datasets. Metadata has been compiled by the Bioregional Assessment Programme.\n\n\n\nCartographic masks for map products GAL_115, used for clear annotation and masking unwanted features from report maps.\n\n## **Dataset History** \n\nA shapefile was created for the use of masking data to highlight text.\n\n\n\nMethod:\n\n\n\n\\* A new polygon shapefile was created with no content\n\n\\* The shapefile was then populated in an ArcMap editing session by digitizing polygons which surround text.\n\n\\* ArcMAP's Advanced Drawing Option was then used to mask data behind text.\n\n## **Dataset Citation** \n\nBioregional Assessment Programme (2014) Cartographic masks for map products GAL115.

## 摘要

本数据集由生物区域评估计划（Bioregional Assessment Programme）为制图需求创建，未使用任何现有源数据集进行衍生制作，元数据（metadata）由生物区域评估计划编制。
本数据集包含针对地图产品GAL_115的制图遮罩，用于对报告地图进行清晰标注并遮蔽非必要要素。

## 数据集历史

曾创建一个形状文件（shapefile），用于对数据进行遮罩处理以突出显示文本内容。

## 方法

* 新建一个无内容的多边形形状文件
* 在ArcMap编辑会话中，通过数字化环绕文本的多边形完成该形状文件的填充
* 随后使用ArcMAP的高级绘图选项对文本后方的数据进行遮罩操作
