Spatial Data Resources
Branner Earth Sciences Library and the Stanford Geospatial Center host a comprehensive set of base and thematic spatial data as well as a large collection of static maps. Please contact us to get a tour of the SGC data collection or set up a data research reference appointment.
Earthworks is Stanford University Library's portal for discovery and distribution of geospatial data. Earthworks provides federated search of more than a dozen other research collections and direct access to data for download. Earthworks currently contains records for over 72,000 spatial datasets and cartographic resources, with over 58,000 of those freely available under permissive licensing.
You can begin your search for GIS data online at EarthWorks, Stanford's cross institution geospatial discovery application:
Using Stanford's locator.stanford.edu Geocoding Service
The Stanford Geospatial Center maintains an ArcGIS Server-based geocoding service for research and teaching use. This service is meant to be used for bulk geocoding of thousands to millions of placenames and/or addresses in North America.
To access the Address Locator services:
- In ArcCatalog, or the Catalog Panel in ArcMap, expand the GIS Servers item
- Double-click the Add ArcGIS Server item
- Leave the default "Use GIS Services" option, click Next>
- For the 'Server URL' use: http://locator.stanford.edu/arcgis
- For 'User Name' use your SUNetID (prefixed with the 'WIN' domain) as WIN\SUNetID
- Enter the password associated with your SUNetID and check the option to Save Username/Password
- Click Finish
You should then be able to use the various Address Locator Services for bulk geocoding in ArcGIS.
What's Currently Available on locator.stanford.edu
The address locators inside the geocode folder include a Composite (capable of street addresses and postal codes) service for North America and separate services for U.S. Street Addresses and Postal Codes. There are also street address, placename and administrative unit locators for Brazil.
The address locators in the Rio folder include Address Locators built by The Spatial History Project at Stanford's Center for Spatial and Textual Analysis (CESTA). For more information about these geocoding services, see the Spatial History Project's Rio de Janeiro Historical Address Locator page.
Are You an R User?
Stanford Library's Claudia Engel maintains a repo with scripts for using the Stanford Geocoding Service in R. Find them here: https://github.com/cengel/ArcGIS_geocoding
