SLIDE 11

Take measurements from the models because they remove distortion present in 2D photographs

Obtain accurate renditions of archaeological features/artifacts

Photogrammetry provides an opportunity to preserve cultural heritage in an electronic format
Ex. Assyrian reliefs destroyed by Isis
Reconstruction of damaged buildings

Cultural Heritage

Photogrammetry provides an opportunity to “democratize” information and make it available to

the public

Ex. 3D city models
