Which is the target feature in ArcGIS Spatial join?
The target features can be any spatial data source supported by ArcGIS. The attributes from the join features are 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.
How is a spatial join different from a join?
Joins attributes from one feature to another based on the spatial relationship. The target features and the joined attributes from the join features are written to the output feature class. A spatial join involves matching rows from the Join Features to the Target Features based on their relative spatial locations.
What does join one to many mean in ArcGIS?
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.
When to use a radius of 100 meters for spatial join?
Using a search radius of 100 meters with the spatial relationship INTERSECT is the equivalent of saying: if a join feature is within 100 meters of a target feature, consider the join feature to be a match.
How to make a join field unique in ArcMap?
The Input Join Field and the Output Join Field can have different names. If a join field has the same name as a field from the input table, the joined field will be appended by _1 (or _2, or _3, and so on) to make it unique. If values in the Output Join Field are not unique, only the first occurrence of each value will be used.
What does the input table do in ArcGIS?
The Input Table can be a feature class (including shapefile) or a table. All fields in the Input Table will be kept during the join. Optionally, only selected fields from the Join Table will be added to the output.
