Letter Intersections (Defense)

ArcGIS Pro 3.4 | | Help archive

Summary

Identifies intersections in a line feature class and adds sequential letters to output point features.

Usage

  • When naming a new field to letter in the Field to Letter (New Field Name) parameter, the first letter must be an alpha character, and the remaining letters must be alphanumeric or underscores.

Parameters

LabelExplanationData Type
Input Line Features

The input line features with intersections that will be lettered.

Feature Set
Output Intersection Points Feature Class

The output point feature class.

Feature Class
Field to Letter (New Field Name)

The name of the field that will contain the letter designator for each intersection.

Field
Input Area to Letter
(Optional)

The area that will limit the intersections identified; only intersections within this area will be identified and lettered.

Feature Set
Spatial Sort Method
(Optional)

Specifies how features will be spatially sorted for the purpose of lettering. Features are not reordered in the table.

  • Upper rightFeatures will be sorted starting at the upper right corner. This is the default.
  • Upper leftFeatures will be sorted starting at the upper left corner.
  • Lower rightFeatures will be sorted starting at the lower right corner.
  • Lower leftFeatures will be sorted starting at the lower left corner.
  • Peano curveFeatures will be sorted using a space-filling curve algorithm, also known as a Peano curve.
  • CenterFeatures will be sorted starting from a center point (the mean center will be used if no center is provided).
  • ClockwiseFeatures will be sorted starting from a center point and moving clockwise.
  • CounterclockwiseFeatures will be sorted starting from a center point and moving counterclockwise.
  • NoneNo spatial sort will be used. The same order as the feature class will be used.
String
Lettering Format
(Optional)

Specifies the labeling format that will be used for each feature.

  • Excel (A, B, C, ...)An alpha character (for example, A, B, C) will be used. This is the default.
  • Grid (AA, AB, AC, ...)A constant alpha character with an incrementing second alpha character grid (for example, AA, AB, AC) will be used.
  • Alternating Grid (AA, BB, CC, ...)A double alpha character that is incremented for each feature (for example, AA, BB, CC) will be used.
String
Starting Letter
(Optional)

The value that will be used to begin lettering.

String
Omit Letters
(Optional)

The values that will be omitted from the lettering sequence.

String
Minimum Distance Between Output Points
(Optional)

The minimum distance between intersections that are identified for lettering.

Linear Unit
Center Point
(Optional)

The center point that will be used to sort and letter features.

Feature Set
Add Distance and Bearing to Center
(Optional)

Specifies whether fields will be added to the output for distance and bearing to a center point.

  • Do not add distance and bearingNo distance or bearing fields will be added to the output. This is the default.
  • Add distance and bearingDIST_TO_CENTER and ANGLE_TO_CENTER fields will be added to the output.
