Cartographic masks for map products GAL113

## **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\nThis dataset contains shapefiles used mask features and layers in maps which are unwanted, or behind annotation layers, for clearer map presentation. This dataset is used for the report maps in the Bioregional Assessment Galilee Product 1.1 - Chapter 3.\n\n## **Purpose** \n\nCartographic masking to enhance label and feature legibility for maps in chapter 3 of the Bioregional Assessment Galilee subregion Product 1.1\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 GAL113.

**摘要**
本数据集由生物区域评估计划（Bioregional Assessment Programme）为制图需求开发，未基于任何源数据集生成，其元数据由生物区域评估计划编制。

本数据集包含用于遮蔽地图中无关要素与图层，或注记图层后方内容的形状文件（shapefile），以优化地图展示效果。该数据集用于生物区域评估项目Galilee产品1.1第3章的报告用图制作。

**用途**
用于对生物区域评估Galilee分区产品1.1第3章的地图进行制图遮蔽，以提升注记与地图要素的可读性。

**数据集历史**
本数据集最初为遮蔽数据以突出文本内容而创建形状文件。

制作方法：
· 创建一个空的多边形形状文件
· 在ArcMap编辑会话中，通过数字化环绕文本的多边形来填充该形状文件
· 随后使用ArcMAP的高级绘图选项（Advanced Drawing Option）为文本后方的数据添加遮蔽效果。
