Relocation: Holographic techniques will be used to graphically simulate the results of a proposed building relocation project by providing a projected (free space) 3-D model of the structure in its new location. This will assist preservation architects in overall site selection and building placement, and in other design and planning considerations. Examination and evaluation of the structure prior to the move will depend on holographic modeling to facilitate X-ray and CAT scan analysis of component building parts. The computer generated holographic representation will not only facilitate the relocation decision process, but it can also be used to simulate the spatial and aesthetic impact of proposed changes to the historic scene, and will contribute to the determination of effect in cases of encroachments from development projects that threaten the integrity of the historic resource. Holographic techniques will assist in the interpretation of the historic structure to the public during and after the move. Projected Holography Preservation Design
