Cartographic masks for map products GIP 120

## **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 1.1.7. The processes undertaken to produce this dataset are described in the History field in this metadata statement.\n\n\n\nThis layer has been superseded by Cartographic masks for map products GIP 120 v02\n\n## **Purpose** \n\nCartographic masks for map products GIP_120, used for clear annotation and masking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 GIP 120.

## **摘要**

本数据集由生物区域评估计划（Bioregional Assessment Programme）为制图目的开发，未源自任何源数据集，其元数据亦由该计划编制。

本数据集由生物区域评估计划开发，用于吉普斯兰盆地（Gippsland Basin）生物区域成果1.1.7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。

此图层已被地图产品GIP 120 v02的制图掩膜（Cartographic masks）所替代。

## **用途**

用于地图产品GIP_120的制图掩膜，可实现清晰标注，并对报告地图中的冗余要素进行遮蔽处理。

## **数据集历史**

最初创建形状文件（shapefile）用于遮蔽数据以突出显示文本。

制作方法：

1. 新建一个无内容的多边形形状文件（shapefile）；
2. 在ArcMap编辑会话中，通过数字化环绕文本的多边形为该形状文件填充要素；
3. 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。
