Geocoding is the process of converting location information - such as street addresses or place names - into geospatial data that can be displayed as features on a map. This page provides more information about geocoding options associated with Esri licensed resources, including use of ArcGIS Online for small batch geocoding and a geocoding service provided to Ohio State affiliates for large batch geocoding.
Ohio State affiliates can use the university's ArcGIS Online organization for geocoding in the course of university-related activities permitted under the terms of our Esri institutional agreement. As geocoding in ArcGIS Online is one of the more expensive operations in terms of credit consumption, it is recommended only for small batch geocoding of 10,000 records or less (and see the credit policy page for more information about use of credits in ArcGIS Online).
ArcGIS Online should only be used for geocoding data that are able to be shared externally. If you are working with S2 - Internal or S3 - Private data, we recommend using the geocoding service detailed below. Additionally, ArcGIS Online cannot be used for geocoding data that is classified as S4 - Restricted data. If you have questions regarding options for geocoding S2, S3, or S4 data, please contact email@example.com.
This short tutorial on converting a list of historic places into a map provides an introduction to the geocoding workflow in ArcGIS Online (in this case using place names, but the workflow is largely the same when using street addresses). If you need to create your Ohio State ArcGIS Online organizational account, please see the instructions provided on the ArcGIS Online page.
To provide a convenient alternative for large batch geocoding by Ohio State students, staff, and faculty, the Center for Urban and Regional Analysis (CURA) operates a geocoding service with coverage of the United States based on Esri Business Analyst datasets.
The geocoding service is available for Ohio State students, staff, and faculty to use for university-related activities permitted under the terms of our Esri institutional agreement. The service cannot be used for commercial purposes or by third parties not affiliated with Ohio State.
Data derived from the service cannot be delivered to third parties not affiliated with Ohio State without making a request to firstname.lastname@example.org for consideration.
The service cannot be used for geocoding data that is classified as S4 - Restricted data. If you have questions regarding options for geocoding S4 - Restricted data, please contact email@example.com.
There is a limit of 200,000 geocodes per batch. Larger datasets may be geocoded using multiple batches.
There is no assumption of accuracy or quality of the service or its results. The service is provided as-is.
The service may be discontinued at any time due to abuse or changes to the terms of our Esri institutional agreement.
We do not offer instructions on the use of the service beyond what is found on this page below. Esri provides additional documentation on geocoding with ArcGIS Pro.
If you need to install and license ArcGIS Pro before using the geocoding service, please see the instructions provided on the ArcGIS Pro page.
