Can a feature be joined based on an attribute?
An attribute join matches features based on field values. You can join features based on a spatial relationship, a temporal relationship, an attribute relationship, or a combination of the three.
How does spatial join work in ArcGIS Pro?
A spatial join matches features (rows) from the input features (the Target Layer and Join Layer parameters) based on their spatial locations. A temporal join matches features (rows) from the input features based on their temporal relationships. An attribute join matches features based on field values.
How are join features aggregated in ArcGIS Pro?
Join one to one —The attributes from the multiple join features will be aggregated. For example, if a point target feature is found in two separate polygon join features, the attributes from the two polygons will be aggregated before being transferred to the output point feature class.
When does a point become a join feature?
A point can be a join feature only if a point is also a target feature. If the entirety of the feature in the join features is on the boundary of the target feature, the feature will not be matched. Touches — The features in the join features will be matched if they have a boundary that touches a target feature.
Which is an example of a join feature?
Joins attributes from one layer to another based on spatial, temporal, or attribute relationships, or a combination of those relationships. Both examples show a spatiotemporal join using the Join Features tool.
Can a target feature contain a join feature?
Contains — The features in the join features will be matched if a target feature contains them. The target features must be polygons or polylines. The join features can only be polygons when the target features are also polygons. A polygon can contain any feature type. A polyline can contain only polylines and points.
When to check all features in a join layer?
When checked, all features in the target layer are returned in the output, even if the target feature does not have a match in the join layer (a left outer join). An example of one-to-one and one-to-many attribute joins, with and without Keep all target features checked.
