Cartographic masks for map products GIP 114

## **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 1.1.4. 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 114, 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 114.

**摘要**

本数据集由生物区域评估计划（Bioregional Assessment Programme）为制图需求编制，未源自任何现有源数据集，元数据由该计划编撰。

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1.1.4的制图输出。本数据集的制作流程详见本元数据说明中的“历史”字段。

**用途**

用于地图产品GIP 114的制图遮罩，可实现清晰标注，并对报告地图中的无关要素进行遮蔽。

**数据集历史**

最初创建了一个形状文件（shapefile），用于遮罩数据以突出显示文本。

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完成该形状文件的填充

· 使用ArcMAP的高级绘图选项对文本后方的数据进行遮罩处理。
