Jardim Garcia quarry

This dataset is composed by an image set and part of a Digital Outcrop Model of the west side of the Jardim Garcia quarry, a ∼25 m high and ∼200 m long SSE-NNW rock wall. It belongs to a deactivated quarry situated at the outskirts of Campinas City (São Paulo State, southeastern Brazil), composed of mafic intrusive rocks from Serra Geral Formation (Cretaceous, Paraná Basin) and used as a recreational area for activities such as rock climbing and aeromodeling.

The images were acquired by a DJI Phantom 4 Pro. The automatic flight was programmed using Litchi App. For georeferencing the final 3D model, climbing anchors were surveyed by irradiation from a total station located in an open traverse. The traverse coordinates were obtained by geodetic GNSS post-processing.
