Creating a circle/bearing intersection

The Circle Bearing Intersection function creates a point at the location where the heading for a bearing and a radius intersect.

Pasos:

1. Start ArcMap.
   Sugerencia:

   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.

   Sugerencia:

   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 Circle Bearing Intersection 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
   Sugerencia:

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

6. Repeat step 5 to define a coordinate for the starting point of the azimuth vector.
7. Click the cell next to Radius and type a value for the radius of the circle that is going to be created using the first coordinate.

   This is the radius of the first circle created based on the first coordinate. The default unit is Nautical Miles.

Sugerencia:

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 Azimuth and type a value for the azimuth of the second point.

   The azimuth is the angle at which the output coordinate should be calculated. The default unit is degrees.

   The azimuth used should be in a direction that is going to intersect the circle created using the first coordinate.

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. If necessary, click the cell next to MagVar Value and type a value for the magnetic variation.

   This can be a specified value or from a field defined in the MagVar Source parameter. The default unit is degrees.

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.

10. If necessary, click the drop-down arrow next to MagVar Year and choose a different year for the World Magnetic Model.

    This is the year associated with the magnetic variation value.

11. If necessary, click the drop-down arrow next to MagVar Source and choose a source for the magnetic variation.

    This is the source of the magnetic variation value.

12. Click the cell next to Interval and type a value.

    This is the length of the segments that are searched for an intersection between the coordinates and the cutoff point. The default unit is Nautical Miles.

13. Click the cell next to Cutoff and type a value.

    This is the maximum distance that can be searched for an intersection from the first and second coordinates.

14. Click the Execute button .

A point appears at the location where the bearing and the radius intersect.

Sugerencia:

If the circle and intersection point do not appear, click the Add Scratch Data Layers button at the top of the Feature Builder window.
