Creating a buffered segment

The Segment Buffer function creates a polygon feature based on a segment created by two defined coordinates.

步骤:

1. Start ArcMap.
   提示:

   If the ArcMap - Getting Started dialog box appears, you can open a new or existing map document. You can also check the Do not show this dialog box in the future check box and click Open.

2. On the menu bar, click Customize > Toolbars > Production Feature Builder.
3. Click the Launch Feature Builder button on the Production Feature Builder toolbar.

   The Feature Builder window appears in ArcMap.

   The Feature Builder window

   提示:

   The Feature Builder window can be placed anywhere in ArcMap, or in the TOC, with the aid of the arrows showing the possible placement positions.

4. Choose Segment Buffer in the list on the Functions tab.

5. Define a coordinate for the start point of the polyline by doing one of the following:
   • Clicking the Pinprick button on the Production Feature Builder toolbar, then clicking on the map
   • Typing the coordinates in the cells on the Input tab in the Coordinates area
   提示:

   To view the input coordinates on the map, double-click the row headers for each coordinate.

6. Repeat step 4 to define a coordinate for the endpoint of the segment.
7. Click the cell next to Left Buffer and type the value for the left buffer.

   This is the width of the buffer to the left of the segment. The default unit is Nautical Miles.

   提示:

   You can right-click the parameter name and change the unit of measurement. If you change the unit of measurement after defining a value, the value is converted to the new unit of measurement, and you may need to redefine the value.

8. Click the cell next to Right Buffer and type the value for the right buffer.

   This is the width of the buffer to the right of the segment. The default unit is Nautical Miles.

   提示:

   You can right-click the parameter name and change the unit of measurement. If you change the unit of measurement after defining a value, the value is converted to the new unit of measurement, and you may need to redefine the value.

9. Click the drop-down arrow next to Buffer End Type and choose the type of corners to add to the ends of the buffer segments.
   • Clipped—The corners of the buffer are squared, so the geometry is rectangular.
   • Elliptic—The corners of the buffer are round, so the geometry is an oval.
10. Click the Execute button .

A polygon feature is created.

提示:

If the polygon does not appear, click the Add Scratch Data Layers button at the top of the Feature Builder window.
