Cartographic masks for map products GIP 113

## **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\nThe dataset was created by the Bioregional Assessment Programme for use in cartographic outputs in Gippsland Basin bioregion product 1.1.3. The processes undertaken to produce this dataset are described in the History field in this metadata statement.\n\n## **Purpose** \n\nCartographic masks for map products GIP 113, 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 (2015) Cartographic masks for map products GIP 113.

**摘要**
本数据集由生物区域评估计划（Bioregional Assessment Programme）编制，旨在满足制图需求。本数据集未依托任何源数据集构建，其元数据由生物区域评估计划整理编制。

本数据集由生物区域评估计划编制，用于吉普斯兰盆地（Gippsland Basin）生物区域产品1.1.3的制图成果制作。本数据集的生成流程详见本元数据声明中的“历史”字段。

**用途**
用于地图产品GIP 113的制图掩膜，可实现报告地图的清晰标注，并遮蔽无关要素。

**数据集历史**
最初为实现数据遮蔽以突出文本内容，创建了一个形状文件（shapefile）。

制作方法：
* 新建一个空白多边形形状文件
* 随后在ArcMap编辑会话中，通过数字化勾勒文本周边的多边形完成文件填充
* 最终借助ArcMAP的高级绘图选项，为文本后方的数据添加掩膜。
