- Click the Bookmarks menu and select the Research areas bookmark-only area bookmark.
The map zooms to the Goose Creek area of the park. The polygons depict research-only areas. - In the Table of Contents, uncheck the Streams layer to turn it off.
This makes it easier for you to see and select the correct features. - On the Edit toolbar, click the Select tool.
- Select the southernmost Research areas polygon—the tan-colored one, as shown below.
- On the Edit toolbar, select Modify from the Features group.
This will open up the Modify Features window, which has a list of all the available tools. - Select Buffer from the Construct tools group.
- Select Buffer zones from the Template drop-down list.
The Select Feature Template window shows only templates that are valid output types for the particular command rather than all the templates listed on the Create Features window. In the case of Buffer, polygon and line templates would be listed, if available, since both these geometry types can store the new buffer feature. On the other hand, when using a command, such as Copy Parallel, that creates line features, only line feature templates are listed for that command. If you want to find a template by name, you can enter it into the <Search> box. - Next to ‘Buffer Distance’ type “300” and select m instead of the default ft.
This means a buffer will be created 300 meters (the map units) from the border of the selected polygon.
Click Buffer.
