Introducing the CAPA-Auriela Dealey Plaza Digital Twin, a comprehensive preservation and research data set that offers sub-centimeter accuracy. The data set includes LiDAR and drone photogrammetry raw data, with pre-calculated 3D models, making it perfect for a range of research and educational purposes such as ballistic modeling, acoustic modeling, documentary animation, historical reconstruction and much more.
A 60th Anniversary Flagship Project
Mid-2023, CAPA-Auriela Dealey Plaza Digital Twin developer Irving Nestor learned of the talks about changing Dealey Plaza drastically from its current near-unchanged form. As the owner of a film, media and marketing business, he knew he could convert the current physical state of the Plaza into a forensically valid 3D model to preserve the space– as long as there was funding.
That’s when CAPA came in. CAPA (Citizens Against Political Assassinations), an esteemed group of JFK Assassination research devotees and legends of the time, agreed to fund the project when presented with the concept.
Irving’s inaugural presentation of this historic project at the CAPA-Wecht Institute 60th Anniversary dinner.
PPK Drone Photogrammetry
Drones allow us to gather spatial data with more positional freedom.
- Roofs, building details, overpasses, etc. are accessible and without interference from ground objects
- High resolution & quality visual spectrum photography
- Large ground coverage
- GPS metadata and PPK base station data increases reference accuracy to the real world and reduces photogrammetry computational load
- 10,409 photos taken of entire subject area at varying altitudes and angles
- Equipment: Mavic 3 Enterprise & RTK Module (using its wide angle lens)
Ground-Based LiDAR Scan
- Trees, overhangs, alcoves, dark areas, etc. are accessible
- 360-degree visual spectrum panoramas taken simultaneous to each scan
- 411 LiDAR scans with 10 million point measurements per scan
- Color calibration cards present in each panorama
- User-friendly web-based previewing via Matterport
- Standardized scan height to the average human male of the 1960s
- Pre-stitched and lighter data set for computation and viewing
- Equipment: Matterport Pro3
