For this option, the target features cannot be points, and the join features can only be polygons when the target features are also polygons. The target features must be polygons or polylines.

CONTAINS - The features in the join features will be matched if a target feature contains them.

Specify a distance in Search Radius parameter.

WITHIN_A_DISTANCE_3D - The features in the join features will be matched if they are within a specified distance of a target feature in three-dimensional space.

Specify a distance in the Search Radius parameter.

WITHIN_A_DISTANCE - The features in the join features will be matched if they are within a specified distance of a target feature.

INTERSECT_3D - The features in the join features will be matched if they intersect a target feature in three-dimensional space (x, y, and z).

INTERSECT - The features in the join features will be matched if they intersect a target feature.

For example, if a single point target feature is found within two separate polygon join features, the output feature class will contain two copies of the target feature: one record with the attributes of one polygon, and another record with the attributes of the other polygon.

JOIN_ONE_TO_MANY - If multiple join features are found that have the same spatial relationship with a single target feature, the output feature class will contain multiple copies (records) of the target feature.

The JOIN_ONE_TO_ONE option is the default. If one polygon has an attribute value of 3 and the other has a value of 7, and a Sum merge rule is specified, the aggregated value in the output feature class will be 10. For example, if a point target feature is found within two separate polygon join features, the attributes from the two polygons will be aggregated before being transferred to the output point feature class.

JOIN_ONE_TO_ONE - If multiple join features are found that have the same spatial relationship with a single target feature, the attributes from the multiple join features will be aggregated using a field map merge rule.

For example, if a point is WITHIN three polygons, then the point is counted three times, once for each polygon. If a join feature has a spatial relationship with multiple target features, then it is counted as many times as it is matched against the target feature. Learn more about how proximity is calculated If you want to find the 2 nd, 3 rd, or N th closest feature, use the Generate Near Table tool. When this situation occurs, one of the join features is randomly selected as the matching feature (the join feature's FID does not influence this random selection). When the Match Option is set to CLOSEST, it is possible that two or more join features are at the same distance from the target feature. For example, 15.5,, and 2.5 will result in 9.0 for Mean and 2 for Count. Null values in join fields are ignored for statistic calculation. For example, if three features with DEPTH attribute values of 15.5, 2.5, and 3.3 are joined, and a merge rule of Mean is applied, the output field will have a value of 6.1. Merge rules specified in the Field Map of Join Features parameter only apply to attributes from the join features and when more than one feature is matched to a target feature (when Join_Count > 1).

Keep All Target Features is checked (set to KEEP_ALL in scripting).

The Join Operation is set to JOIN_ONE_TO_ONE, and.A value of -1 for JOIN_FID field means no feature meets the specified spatial relationship with the target feature.ДЄll input target features are written to the output feature class only if: The JOIN_FID field makes it easier to determine which feature is joined to which target feature (TARGET_FID). When the Join Operation parameter is JOIN_ONE_TO_MANY, there can be more than one row in the output feature class for each target feature. Join_Count indicates how many join features match each target feature (TARGET_FID).ДЄnother new field, JOIN_FID, is added to the output when JOIN_ONE_TO_MANY is specified in the Join Operation parameter. Two new fields, Join_Count and TARGET_FID, are always added to the output feature class.

You can define which of the attributes will be written to the output by manipulating them in the Field Map of Join Features parameter. A spatial join involves matching rows from the Join Features to the Target Features based on their relative spatial locations.Д«y default, all attributes of the join features are appended to attributes of the target features and copied over to the output feature class.
