Creating a rhumb line bearing distance

Доступно с лицензией Production Mapping.

The Bearing Distance (Rhumbline) function calculates the output coordinate based on a heading, also an azimuth, and a distance. A line is also created that represents the distance between the input and output points.

1. Запустите 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.

   Подсказка:

   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 Bearing Distance (Rhumbline) 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.

   Подсказка:

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

7. Click the cell next to Azimuth and type the azimuth value.

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

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 Distance and type the distance value.

   The distance value represents the amount of space between the input coordinate and the output coordinate. The default unit is nautical miles.

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.

10. 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.

11. 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.

    Примечание:

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