OCHOA-ARIAS, Paúl  and  DELGADO-PINOS, Omar Andrés. 2D and 3D Photogrammetric Registration Model of the Built Heritage of Cuenca. Universitas [online]. 2020, n.33, pp.163-180. ISSN 1390-8634.  https://doi.org/10.17163/uni.n33.2020.08.

Participatory cultural heritage management involves collaboration of different proposals and participants. In this article, the initiative that allows to register graphically the relevant built heritage of the historic center of the city of Cuenca by means of photogrammetry, and the management of it in a Geographic information System have been developed. The photographic study of the property or object is carried out (from multiple angles) by using individual or mounted on drone’s cameras. Certain processes, supported by specialized software, are applied to this material to obtain a mosaic of images with which it is possible to obtain the correction of the perspective in the images (photogrammetry). Printable digital products are obtained in two-dimensions (paper) and three-dimensions (resins) forms with scale and precision. Compared to other procedures, this proposal has several advantages: ease, speed, low costs, good quality of the products. Although, we must also acknowledge some limitations. After the development of the project, it can be established that the technical and methodological availability allows to obtain a digitally documented information model integrated into a Geographic Information System; which has property information (cadastral record), delimitation of the areas of heritage value, representation of the two-dimensional and three-dimensional buildings, access to the respective website.

Keywords : Architectural photogrammetry; built heritage; 3D models; orthophotography; Geographic Informatio System; Geomatics.
