Inserting the Topo North Arrow element (Production Mapping)

The Topo North Arrow is a declination diagram that can be placed in the page layout and represents the three norths:

North Arrow

This element can be converted to a graphic to allow alterations. You can ungroup the element and alter it by selecting the element, clicking Convert To Graphics, then clicking Ungroup to ungroup the elements. Perform the required edits, then regroup the elements by selecting them all and clicking Group. However, once you convert this element to a graphic, it becomes a group of lines, and text and is no longer configurable as a north arrow.

步骤:
  1. Start ArcMap.
  2. Load data into the map or open an existing map document.
  3. Verify that the map is in layout view.
  4. On the main menu, click Insert > Topographic > Topo North Arrow.

    A default north arrow is added to the layout. Continue with the next steps if you want to modify the properties for this element.

  5. Double-click the north arrow element.

    The Topo North Arrow Properties dialog box appears.

  7. if necessary, click the Date drop-down arrow to choose the declination date you want to use.

    Any date between 2005 and 2014 is currently supported.

  8. Uncheck the Update dynamically check box if you want to modify the element properties.

    When this check box is checked, the magnetic north, grid north, mils, and UTM zone are calculated using the current date and centerpoint of the active data frame.

  9. Perform the following for both the Magnetic North and Grid North area options:
    1. Click West or East for your north arrow.
    2. Type or select the number of degrees you want to use in the Degrees text box.
      注注:

      Modifying the value automatically sets the Mils value. You can also override the default Mils calculation by typing a value in the Mils text box.

    3. Type or select the number of minutes you want to use in the Minutes text box.

    注注:

    Modifying the UTM Zone parameter automatically populates the Grid North Degrees, Minutes, and Mils values. This property is useful for determining the grid north on a map with a UTM zone that differs from the centerpoint of the current map (that is, for maps with two UTM zones).

    The Spatial Reference Properties dialog box appears.

  11. Click Select.

    The Browse for Coordinate System dialog box appears.
