Evan Patz — Geospatial Developer & Designer

Evan is a geospatial developer and designer based in NYC. He builds interactive web maps that make complex data legible through narrative structure and visual design. His background in engineering, computer science, and sustainable energy shapes the technical foundation of this work, while a lifelong passion for photography inspires his visualization approach.

His introduction to geospatial work traces back to his graduate thesis at Columbia University, where he used GIS and statistical methods to forecast electricity demand across the US by layering geographic, demographic, and energy data. From there, he moved into the sustainable energy industry, where spatial data was central to the work and gave him both the domain knowledge behind his visualizations and a practical fluency with complex geographic datasets.

Today, Evan handles the full stack from data to design to development: researching and sourcing datasets, cleaning and transforming spatial data in Python, analyzing and processing it in QGIS, designing visuals and narrative, and building the final interactive front end in JavaScript and HTML. The decisions at each stage are where his technical expertise and visual eye meet, creating captivating and impactful works.
