Press Release – Georgia O’Keeffe House

Press release


3D Pointcloud > 2D Orthophoto > Vector Line Drawing

Dense 3D Point clouds, Orthophotos and Measured line drawings together make a strong trio as elements of a thorough architectural documentation/survey. All of these products can be derived from photogrammetry.

This is a low res model derived from a super dense point cloud that captures the existing conditions of this beautiful wood carving from 1795. The building currently houses offices for The National Park Service in Philadelphia’s Old City.

Aaslestad Preservation Consulting is providing project architects  Mills + Schnoering with existing conditions documentation that will be “in hand” when the team goes up to do hands-on preservation/conservation work later this month.
