Geocoding is the process of transforming a description of a location—such as a pair of coordinates, an address, or a name of a place to a location on the earth's surface. You can geocode by entering one location description at a time or by providing many of them at once in a table. The resulting locations are output as geographic features with attributes, which can be used for mapping or spatial analysis. You can quickly find various kinds of locations through geocoding.
HOW TO GEOCODE LARGE DATASETS
Geocoding using ArcGIS Online consumes credits. Each Clemson user has a total of 3,000 credits. If you are geocoding thousands of points, you will use all of your credits and won't be able to use ArcGIS Online for the intended functionality (publishing data, story maps, etc).
CCGT has its own dedicated GIS server that provides geocoding services to the Clemson community free of charge and without taking any credits. Users can geocode millions of points without any issues or concerns.
If you wish to learn how to geocode without using your credits, please watch this video, and follow this tutorial.
