Where ideas become working code.

Building the Future of Geospatial Standards

Builder Days are intensive, hands-on working sessions where developers, implementers, and standards experts come together to prototype, test, and refine candidate standards. It’s where specifications meet implementation, with participants building and testing together to find what works, identify what doesn’t, and improve standards before they move forward.

Who Participates?

Builder Days bring together developers, software architects, implementers, and anyone who wants to help shape emerging standards through practical collaboration. They’re also an accessible way for organizations to sponsor innovation without committing to a full Testbed.

How It Works

Start with a Challenge

Participants focus on a candidate standard, API, building block, or interoperability challenge.

Build Together

Working side by side—in person and online—the community prototypes, tests, and improves emerging specifications.

Feed It Back

The results go directly to the Domain and Standards Working Groups, helping refine specifications before broader implementation through Apply.

Why Builder Days?

Builder Days put emerging standards into practice early. By bringing developers, implementers, and standards experts together to build, test, and work through issues in real time, they expose what works, what doesn’t, and what needs to change before broader implementation.

Part of Connect

Builder Days are one of the ways the OGC community comes together. They connect the collaborative energy of Connect with the standards work of Build and the broader implementation activities of Apply.
