Program Area: GEO
Geospatial Data & Tools for AnalysisOverviewGeoQuery.org
More data is available today than ever before, but organizations often don't have the means to use it. AidData's GEO program breaks down technological barriers and empowers a broad range of data users to produce new and meaningful research and insights using next-generation geospatial data, methods and tools.
Our powerful spatial data integration and extraction infrastructure is available for free public use through GeoQuery, a ground-breaking project that enables users without significant computing power or expertise to easily find, access and merge together spatial data from a wide variety of sources.
The GEO program also creates new datasets with information on development outcomes captured frequently and at high levels of spatial detail; provides the largest open-source repository of data on geographic boundaries; and innovates new geostatistical analysis and machine learning-based methods.
GeoQuery enables individuals and organizations without significant computing power or data science expertise to freely find and aggregate satellite, economic, health, conflict, and other spatial data from anywhere in the world into a single, simple-to-use file.
GeoBoundaries provides accurate data on the geographic boundaries of administrative areas around the globe. Unlike other boundary datasets, GeoBoundaries is an open product: all boundaries are free and redistributable, and are released with extensive metadata and license information to inform users.
For geospatial experts, GeoSIMEX is a geospatially-adapted SIMEX (simulation and extrapolation) model available as an R package. It helps research models establish a relationship between measurement error and covariate bias introduced by geospatial uncertainty to estimate the impact an intervention had.
Recent work has proven the effectiveness of satellite imagery and convolutional neural network (CNN)-based machine learning methods to predict poverty. AidData and its partners explore these data and methods, apply them in real world applications, and provide tools for other other researchers.

How GeoQuery works
GeoQuery performs advanced spatial statistics to extract data from open-source datasets on topics on such as:
- International Aid
- Population and the Environment
- Conflict and Health
- Economic Development
- Access to Infrastructure
Every data request you make returns an email with a single CSV where each row is a geographic boundary and each column is a requested dataset. This file can be read by nearly all software packages, and we also include a full PDF of metadata. All requests are made accessible at a unique, permanent URL to promote data sharing. See our Quick Start Guide.
