A research project at AidData

Integrate satellite, conflict, aid, economic, health and more subnational data, from anywhere in the world, into a single simple-to-use file compatible with Excel, STATA, or your own favorite program.

Get Started

Want to use spatial data, but don't have experience using ArcGIS, Q, or other programs for satellite imagery or spatial data analysis? Our Quick Start Guide walks you through a simple spreadsheet-based analysis using data downloaded from GeoQuery, designed to be completed in under 10 minutes.


Researchers at William and Mary

GeoQuery is a part of AidData, a research lab at William and Mary. With one foot in applied practice and the other academia, we are able to provide open access to our data thanks to the contributions of full-time GIS analysts and engineers, faculty members, and students from nearly all walks of life. Click here to meet our students, or head over to AidData to see our faculty and staff.

Applied Practitioners

We've conducted analyses with the same data available on this site for dozens of organizations, including the World Bank, GEF, KFW, USAID, and more. As a part of these and other projects, AidData staff and faculty have been creating and integrating geospatial data for over 10 years, and every datasets that is included in GeoQuery is extensively vetted for accuracy.

Committed to Transparency

Every line of our code is open source, and we provide human readable documentation on every procedure and step GeoQuery uses to process data. We also regularly present our work at conferences, publish in peer-reviewed outlets, and provide all of the raw data used in GeoQuery for download by experts.


Every request you make will return an email with a single CSV where every row is a geographic boundary and every column is a requested dataset. This file can be read by nearly all software packages, and we also include a full PDF of metadata - you can download an example here. All requests are made accessible at a unique, permanent URL to promote research replication and data sharing. Want the technical details? Learn more about how it all works here.

Revolution #14: New Ways to Get Our Data “in the raw”

There are three requests we hear over and over again from researchers: (1) Can I use my own custom boundaries? (2) Can I have the underlying raster data you’re using? (3) Can I visualize the data? For the past two years, the answer to these questions has been “No”, and “maybe someday”. So, I’m very […]

Revolution #13: “The Cloud”

We’ve had a lot of buzz around the office this week about the cloud, generally fostered by our discovery of paperspace (a cool startup that makes rolling your own computers in the cloud much easier).  We’ve dabbled with AWS, Google Compute, and a few other offerings before, but we’re constantly asked (at conferences and internally) […]

Revolution #12: New Year, New Boundaries

As we start the New Year, we will take a break from our regularly scheduled programming to talk about the ever changing state of political boundaries. I work on the GeoBoundaries team, where I come across all kinds of fun facts about the world we live in. I get to decide (or defer to source […]
