Geocoding and Network Analysis 

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 types of locations through geocoding.

Network analysis comprises several types of spatial analysis on transportation networks, such as determining the optimal path or route from one location to another or multiple locations, finding the closest facility, identifying a service area around a location, or servicing a set of orders with a fleet of vehicles.



Clemson University has a small academic license for ArcGIS StreetMap Premium - North America. This solution enables geocoding and network analysis without consuming credits for the following countries: American Samoa, Canada, Guam, Mexico, Northern Mariana Islands, Puerto Rico, Saint Pierre and Miquelon, the United States, and the U.S. Virgin Islands region.


For geocoding on a global scale, ArcGIS World Geocoding Service is available. Please note that Geocoding using ArcGIS World Geocoding Service consumes credits. As for the Network analysis, it consumes 0.005 credits per simple route on ArcGIS Online. 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).




The GIS labs have dedicated computers where ArcGIS StreetMap Premium - North America data are locally installed. These computers would be ideal for HIPPA-compliant tasks in that processes of geocoding and network analysis can be done locally, not over the Internet. Please find the following computers in each GIS lab.

  • Barre Hall, Room 109 (Computer ID: barrb109-01)

  • Cooper Library, Room 412 (Computer ID: coop412-01)

  • Lee Hall, Room 212 (Computer ID: lee212-05)

  • Lehotsky Hall, Room 231 (Computer ID: leho231-01)
