Configuring a calibrated line segment

Segments are a collection of lines that make a neatline. Segments can be calibrated (pattern or line at set intervals) or uncalibrated. Learn more about selecting settings for grid units, map units, angular map units, and relative units.

Segments may only cover a specified portion of the source area of interest side by enabling the Section option. Segment sections allow grid components to only be created for a subsection of the original segment length.

If a neatline has been set to have shared identical segments, the Shared Children text box contains a list of shared segments. The Grids and Graticules Designer determines whether segments are identical. If you want to share segments, you must design segments with identical properties. The easiest way to ensure that the segments have identical properties is to use Copy and Paste on the shortcut (context) menu to create new segments while in the nonsharing mode.

For calibrated segments, the calibration pattern can either begin at the neatline or at the origin of the segment's coordinate system. If the Interval is set to start at the coordinate system, the length calculation can only be done using the Along Axis of Orientation option.

For segment sections, the origin and length of the section must be specified. The origin determines where the section starts in relation to the original segment (the entire length of one of the neatlines' side). Length settings include a specified value and unit of measurement. See Grid units for more information.

步骤:

1. Start ArcMap.
2. Click the Grid and Graticule Designer button on the Production Cartography toolbar.
3. If necessary, click the Neatline component in the tree view on the Grids and Graticules Designer window.
4. Right-click the Neatline component, then click Add > Segment.

   A Segments component is added to the tree view below the neatline.

5. In the tree view, right-click the segments component and choose Properties.

   The Segment Properties window appears.

6. If necessary, click the Segment General tab.
7. If necessary, check the Use Ancillary Coordinate System check box in the Ancillary Coordinate System area to choose an ancillary coordinate system.
   1. Click the Type drop-down arrow and choose an ancillary coordinate system type.
   2. Click the Spatial Reference Properties button .

      The Spatial Reference Properties dialog box appears.

   3. Set the spatial reference properties.
   4. Click OK.
8. Type the number of units to use for an interval in the Interval text box.
9. Choose a unit of measurement for the interval.
10. Choose a pattern option in the Pattern area.
    • Neatline—The pattern starts at the grid's neatline.
    • Coordinate system—The pattern starts at the beginning of the coordinate system.
11. Type a value in the Start text box.
12. Type a value in the Gap text box.
13. Choose an option in the Length Calculation area.
    • Along Axis of Orientation—Determined based on the area of interest's orientation
    • Along Line—Determined based on the selected edge of a polygon feature
14. Choose an option in the Repetitions area.
    • End of Extent—The pattern is repeated indefinitely until the end of the source extent is reached.
    • Custom—You specify the number of repetitions.
15. If the Custom option has been chosen, type a value in the Custom text box.
16. Click the Feature Settings and Symbol tab.
17. If necessary, check the Calibrated Line (checked applies coordinate system settings) check box in the Options area.
18. If necessary, check the Section check box in the Options area and configure the sections by doing the following:
    1. Choose an option in the Origin area.
       • From Point—The same start location as the original segment.
       • Center—The center point of the original segment.
       • To Point—The endpoint of the original segment.
       • Offset—A value and unit can be specified to shift the starting location of the section in relation to the original segment.
    2. Type a value in the Offset text box.
    3. Click the drop-down arrow and choose the unit of measurement to use for the offset.
    4. Type a value in the text box in the Length area.
    5. Click the drop-down arrow and choose the unit of measurement to use for the section length.
19. Click Symbol.

    The Representation Rule Selector dialog box appears.

20. Choose a line symbol and set the appropriate symbol properties.
21. Click OK.
22. Close the Segment Properties window.
