To support the use of geospatial data & technology in research and teaching at Stanford
(whatever that means at any given time)
Treat geospatial technology awareness as information literacy and research skills
We deliver "small bite" targeted services (training, support, consulting, software provisioing, data services), with the objective of building research skills among our users that maximize the use of our data collections, particularly those we spend annual budgets on.
I'd like to do network analysis of optimal delivery routes, based upon rail and navigable waterways...
How do we capture the home locations of cholera patients who live in villages that aren't on the map?
How do I display a photo collection on a web map when there are 170,000 photos in the collection?
I've got a database of 100 million global business addresses. How do I geocode that?
geospatial data is different
it has geometry
and scale
and extent
and temporality

Earthworks.stanford.edu
is powered by the Stanford Digital Repository (SDR) and The Stanford Spatial Data Infrastructure (SSDI)
The SSDI exposes the live OGC spatial data services that power Earthworks fuctionality
(WFS, WMS, etc...)
A geocoding service provides augmentation services for data. Input implicit locations and it returns explicit locations
A geocoding and routing services are some of the most sought after augmentation services in data science. They turn implicitly spatial data into explicitly spatial data
locator.stanford.edu an highly performant geocoding service, based upon Esri's ArcGIS for Enterprise Server
locator.stanford.edu/arcgis
- North & South American Coverage
- Processing of ~ 1 million per hour
- REST API for direct integration
- Multiple inputs:
- Street Addresses
- Administrative boundaries
- Geographic Placenames
- Multiple outputs
- Geographic coordinates
- Administrative geographies
- Normalized inputs
- Uncertainty values

"Spatial" Data is...
- Tabular data
- Vector data
- Pixel data
- Relational data
- Text-based data
- Temporal data
- Complex data objects & formats
In short, if you can make spatial data discoverable, you're already making most data types discoverable.
Services and Access designed in partnership with the people who work directly with our researchers
...for non-librarians.

If we want to be "the face" of data science support and services at Stanford University, we've got to get facetime with data scientists!
