Main contributions of 3D model are:

1- Visualization of different phases or moments of occupation in archaeological sites 2- Generation of ortophotography

3- Integration of other analyses into the 3D model

4- Interpretation and reconstruction of structures in parallel to the process of excavation 5- Better understanding of astronomical events in archaeological structures

6- Producing terrain model for the incorporation of unexcavated structures and archaeological material on the surface

Analysis of proposals of reconstruction to ensure their viability Elimination of proposals unviable from a structural point of view

Identification and better definition of new elements, specially in the Sanctuary:

Presence of second floor in one sector. Analysis of the thicknesses of the walls. Stairway to the wall behind the sanctuary

Potential height and shape of the Gate of the Sun (East gate)

A reconstruction during the excavation created new questions that could be resolved through the parallel process (search for postholes, access to the different rooms, types of coverings). This would not have been possible if the reconstruction had been carried out after the

excavation.
