3DKeene is a free digital archive documenting downtown Keene, New Hampshire, through interactive, walkable 3D scans. Focused on Central Square, Railroad Square, and other downtown locations, the project captures streets and landmarks before, during, and after reconstruction, creating a civic record that visitors can explore in a web browser. Its scans preserve places as they appeared at a particular moment, allowing the public to revisit areas as they change.

The experience features detailed 3D environments made using photogrammetry and Gaussian splatting. Photographs captured from multiple angles are processed into colorful point-based scenes that can be viewed online across a range of devices. The site offers scanned locations, a construction timeline with project photos, and an opportunity for community members to upload their own images and contribute to the record. Visitors can also explore information about downtown and use a traffic tracker for Central Square to check expected wait times. By combining public documentation with emerging 3D technology, 3DKeene helps residents and visitors observe, understand, and remember the transformation of downtown Keene.
