How to use the Spatial Join geoprocessing tool in ArcGIS Pro by Esri. Example data used is from the Hurricane Tracks by USA County video posted a few days earlier than this video. This video is targeted towards GIS students. All parameters of the Spatial Join tool are explained and outputs examined. The common question of source vs target feature layer is addressed in detail by showing how results change when the feature layers are switched around.
