Documenting our excavations in 3D

Since several years we have been using photogrammetry to integrate the documentation of our excavations. Beside drawing and sketching our excavation layers, this technique allows us to register the process in 3D.

Here you can see the beginning of Operation 471, after removing the humus, we had this collapse of a platform building, with no walls exposed.

Prior to the removal of the collapse, also the side of building J37 appeared “messy”. But the intact walls were just underneath the fallen stone blocks. Here you can appreciate how it looks like in Operation 472A!

We are also investigating the front of J37 building, to understand if this mound was actually enclosing a single building or several constructions..In fact, it often happens that the collapse of several contiguous constructions generate a one big mound. Few of the findings of trench 472B have been described in our last post.

While Operations 472A, 472 B and 471 are located in the architectural compound south-east of Group IV, other buildings are being excavated north-east of Group IV (see our recent post).

Operation 473 is exploring a building close to the Takin Ha stream, which runs within our neighborhood. Even with the blue and red colors generated by the tarps we put to create shade on the excavation, it is possible to appreciate the steps leading to the room of the building, as well as the back wall.

Of notice, a flipped metate was placed at the foot of the building (in the blue shaded side of the model)! We found another flipped metate at the base of the pyramid just next to this building, where Dee and Mo started excavating.
