Geocoding is the process of transforming location information (e.g., street addresses, place names, etc.) into coordinate data (e.g., latitude/longitude) that can be plotted and symbolized on a map.

Reverse geocoding is the process of taking latitude and longitude values from a map layer and converting them into street addresses or place names.
 

Add XY Data is a tool that lets users convert a spreadsheet with xy coordinate data (e.g., longitude, latitude) into a geospatial point layer that can be plotted and symbolized on a map.
