6.5.4. Spatial join
In section 6.4.1. spatial queries were performed. In a similar manner, multiple layers can be spatially linked to each other using the Spatial Join (Analysis) tool. Spatial joins allow the attributes of features in separate layers to be linked together based on their shared spatial locations. This is useful for amalgamating different types of information into the same layer. The Spatial join (Analysis) tool can be used to perform this task. The Target Features can be any spatial data source supported by ArcGIS and will be transferred to the Output Feature Class along with the Join Features. The Join Operation determines how joins between target and join featured will be handled if multiple join features have the same spatial relationship with a single target feature; one-to-one or one-to-many (search spatial join in the ArcGIS online help menu for more information).
