We are the Geospatial Experts

We build data systems that add geographic-intelligence to business processes. Oracle, ESRI, Java, FME and more. We combine proprietary and open source components into innovative and cost-effective solutions to our clients' problems.

Technology Mix

Geospatial Technology

We keep on top of the latest changes in enterprise spatial and web mapping technologies. Technologies from Google (Maps, Earth and KML), ESRI (ArcMap, SDE, and ArcIMS), and Oracle (IAS, Spatial, Designer, Database) are key components in the solutions we build.


We are not a vendor, and we recommend solutions that make the best use of your existing physical intellectual capital. A Refractions solution is technically sound, economically feasible, and long-term maintainable.

Open Source Experts

Refractions research is a world leader in open source geospatial technology. We develop the PostGIS spatial database and the uDig GIS desktop framework, and are active participants in many other open source projects.

PostGIS uDig

By using open source components, we can build geospatial systems that are flexible and inexpensive to deploy. Our clients like open source because it keeps costs down. We like open source because it gives us the freedom to innovate and build the best possible solutions.

Case Studies

Natural Language Spatial Search Engine for Rental Places-Rento

Natural Language Spatial Search Engine for Rental Places-Rento

Rento is a free web service that makes it easy to find a place to rent in Greece. Powered by PostgreSQL and PostGIS, it provides ad listings with photographs displayed on a map. Searching is accomplished through map navigation and natural language processing, with the search engine being capable of answering complex (spatial) questions such as "flat near the University of Athens" or "loft up to 800 euros near a metro station" (in greek).
