The attributes from the target features and the attributes from the joined features will be joined to the target features layer. However, a subset of attributes can be defined using the Field Map parameter.
The attributes from the join features will be joined to the attributes of the target features. See the explanation of the Join Operation parameter for details on how the aggregation of joined attributes are affected by the type of join operation.
This parameter is hidden and is not supported. All joins will be performed as a one-to-one join.
To achieve a one-to-many join when the output is created in an output feature class, use the Spatial Join tool.
Keep All Target Features
Specifies whether only target features with a spatial relationship with a join feature (known as an inner join) will be preserved or all target features will be preserved, even without a spatial relationship with the join features (known as an outer join).
The attribute fields that will be in the output with the corresponding field properties and source fields. By default, all fields from the inputs will be included.
Fields can be added, deleted, renamed, and reordered, and you can change their properties.
Merge rules allow you to specify how values from two or more input fields will be merged or combined into a single output value. The following merge rules can be used to determine how the output field will be populated with values:
Specifies the criteria that will be used to match rows.
Join features within this distance of a target feature will be considered for the spatial join. A search radius is only valid when the spatial relationship is specified (the Match Option parameter is set to Intersect, Within a distance, Within a distance geodesic, Have their center in, Closest, or Closest geodesic). For example, using a search radius of 100 meters with the Within a distance spatial relationship will join feature within 100 meters of a target feature. For the three Within a distance relationships, if no value is specified for Search Radius, a distance of 0 is used.
Distance Field Name
The name of a field, which will be added to the join, that contains the distance between the target feature and the closest join feature. This parameter is only valid when the spatial relationship is specified (Match Option is set to Closest or Closest geodesic). The value of this field is -1 if no feature is matched within a search radius. If no field name is specified, the field will not be added to the join.
