Calculate Adjacent Fields (Cartography)

Summary

The most common use case for using this tool is to populate fields that can be used to label the adjacent pages in a map book. This tool appends eight new fields (each field representing one of the eight points of the compass: North, Northeast, East, Southeast, South, Southwest, West and Northwest) to the input feature class and calculates values that identify the adjacent (neighboring) polygons, in each cardinal direction, for each feature in the input feature class.

Usage

Syntax

ParameterExplanationData Type
in_features

Polygon grid index features to be appended with adjacent field data.

Feature Layer
in_field

Field whose values will be used to populate adjacent field data. Use actual field names. Do not use field aliases.
