Creating points

The point component creates a two-dimensional lattice of points that are the intersection of two virtual grid lines. One of the grid lines has an orientation of north–south, and the other is oriented east–west. Points can be used to create ticks, crosshairs, and Military Grid Reference System (MGRS) coordinates. Annotation can be created from points.

Pattern settings for points include:

• Neatline—Point patterns start at the grid's neatline.
• Origin of point's coordinate system—Point pattern starts at the origin of the grid's coordinate system.

In the geodatabase feature class for points (PNT), each point has fields, TEXT_X and TEXT_Y, that store the coordinate location for that point. The values that are stored with the point feature are the actual coordinate values based on the specified coordinate system for the corresponding linear feature.

Repetition settings for points include:

• End of Extent—Pattern continues to the end of the area of interest.
• Custom—You specify the number of repetitions.

On the Feature Settings and Symbol tab, you can specify an angle for the rotation of each point feature's symbol. Angle settings include:

• Perpendicular to Coordinate System—Automatically created based on coordinate system.
• Perpendicular to Segment—Automatically created based on the segment.
• Custom—You set the angle.

On the Feature Settings and Symbol tab, you can choose a symbol from the Representation Rule Selector dialog box.

步骤:

1. Start ArcMap.

   注意:

   Ancillary coordinate systems are optional.

   1. Check the Use Ancillary Coordinate System check box in the Ancillary Coordinate System area.
   2. Click the Type drop down list and choose an ancillary coordinate system type.
   3. If necessary, click the Spatial Reference Properties button .
   4. Choose a coordinate system to use as the ancillary coordinate system.
   5. Click OK.
8. If necessary, click the Point X tab on the bottom of the Point Properties tab.
