Aplicación de la fotografía métrica en edificación mediante el uso de la cámara digital convencional: un caso de estudio aplicado al patrimonio arqueológico = Application of metric photography in building using the conventional digital camera: a case stud

The stratigraphic analysis constitutes an essential diagnostic tool in archelogy works, which allows the archaeologists, historians and anthropologists to decipher the arrangement and interrelation between the different strata and the chronological ordering of the remains found. In this field, the photogrammetry realized with conventional digital camera and software of wide diffusion constitutes a versatile alternative, efficient and affordable in front of the conventional techniques of representation, based on artisan and loaded procedures of subjectivity, whose main limitations are analyzed. This article establishes a simple methodology and a systematic model for the documentation and preservation of stratigraphic units in archaeological excavations, compatible with the technique of stratigraphic analysis based on the Harris matrix. The validity and possibilities of the method have been verified in the project of archaeological intervention developed in the Royal Chapel of the Cathedral of Seville.
