We make your geographic data more valuable by creating beautiful and scalable web and mobile applications, and by creating analytics that uncover insights in your data.

Software Engineering

We can help you increase your organization’s impact by creating web and mobile software that is attractive, easy-to-use, and based on the latest technology.

User Experience Design

Through the development of personas, proven design processes, paper prototyping, and user-centered approaches, our responsive designs will address your audiences and their stakeholders’ distinct needs.

Data Analytics

Turn your data into an asset. By formatting, processing, geocoding, and analyzing your data we’ll help you unearth the unexpected. Harness geospatial analysis and visualization for lasting civic, social, and environmental impact.

Machine Learning and Computer Vision

We complete all steps of the process, from annotating imagery, to training advanced models, to running operations that help you gain insight from massive imagery data sets.

Big Data Processing

We can use GeoTrellis, Spark, Amazon Web Services, and other tools to build complex web applications that work with large data sets by distributing the work across computer clusters.

Research and Development

We both partner with our clients on collaborative research and develop our own research projects. We have extensive experience writing and winning grants from federal agencies and private foundations to support the development of our clients' projects.


We have distilled some of our best work into a few web products that harness the power of geography for positive civic, social, and environmental impact.

Legislative district and elected officials database for district assignment, advocacy, and district mapping to support citizen engagement in the US and other countries.

An open source web application that enables collaborative redistricting, including the ability to calculate metrics on-the-fly during the editing process and evaluate comparison to legal requirements.

An open source software toolkit based on Apache Spark that supports fast geospatial data processing by distributing tasks across computer clusters.

Open source collaborative urban ecosystem tools for tree inventory, community engagement, ecosystem services calculations, and urban forestry analysis.

Open source platform that helps users find, combine, and analyze earth imagery at any scale, and share it on the web.

A guided app for city-based climate change adaptation planners that utilizes our Climate API.

An annotation tool designed for geospatial data, including satellite, aerial, and drone imagery. GroundWork supports object detection, chip classification and semantic segmentation projects, ideal for creating training datasets for machine learning projects.

Open Source

We believe that communities of knowledge, culture and innovation are more vital and energetic when outcomes are shared, enabling others to more effectively build on past work. As active members of a global software community, we think it is useful and important to share some of our knowledge and expertise by making contributions to open source and other community-based software efforts.

Check our GitHub for a list of tools and libraries, as well as our work on the GeoTrellis, OpenTreeMap, OpenDataPhilly, and DistrictBuilder projects. Many of our colleagues are active contributors to other open source projects too.
