Creating a circle/bearing intersection

Available with Production Mapping license.

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

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

   The Feature Builder window appears.

   Tip:

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

4. If the scratch dataset has not been added to the table of contents, click the Add Scratch Data Layers button at the top of the Feature Builder window.

   The dataset is added to the map using the current spatial reference.

5. Choose Circle Bearing Intersection in the list on the Functions tab.

   

6. Define a coordinate for the start point of the polyline by doing one of the following:
   • Click the Pinprick tool on the Production Feature Builder toolbar and click the map
   • Type the coordinates in the cells on the Input tab in the Coordinates area.

   Tip:

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

7. Repeat step 6 to define a coordinate for the starting point of the azimuth vector.
8. 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.

Tip:

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 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.

Tip:

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 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.

    Tip:

    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.

Tip:

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.

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.

Tip:

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.

12. 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.

    Note:

    You can only choose a value for MagVar Year if Magnetic Model is selected for the MagVar Source property.

Tip:

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.

13. 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.

Tip:

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.

14. 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.

Tip:

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.

15. Click the Execute button .

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