Cartographic masks for map products GIP 112

## **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 1.1.2. 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 112, 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 112.

**摘要**

本数据集由生物区域评估计划（Bioregional Assessment Programme）编制，用于制图用途。本数据集未基于任何源数据集生成，其元数据由该计划编制。

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1.1.2的制图输出。本数据集的制作流程详见本元数据说明中的"数据集历史"字段。

**用途**

本数据集为地图产品GIP 112提供制图遮罩，用于实现清晰标注，并移除报告地图中的冗余要素。

**数据集历史**

本数据集最初为高亮文本的数据遮罩需求创建了形状文件（shapefile）。
制作方法：
· 创建一个空的多边形形状文件
· 在ArcMap编辑会话中，通过描绘文本周边的多边形来填充该形状文件
· 使用ArcMAP的高级绘图选项为文本后方的数据添加遮罩。
