Pérdida de edificaciones en tierra en el Centro Histórico de la ciudad de Cuenca-Ecuador.

The Historic Center of Cuenca (CHC), Cultural Heritage of Humanity (PUH) since 1999, manifests its Outstanding Universal Value (VUE) by witnessing the exchange of human values ​​in time reflected in its architecture, technology and urban planning. As for its technology, within the CHC, a large number of structures that contribute to the heritage value of the city still maintain the land as their primary material, however there is also a gradual replacement of ancestral land construction techniques with new architecture or interventions that come from the hand of contemporary materials little compatible. To test this hypothesis, based on the inventories of built heritage assets that have been developed in the city (the year of registration in 1999 and its update in 2010), it is intended through an exploration using geo-reference systems, identify those losses of architecture on land and expose its conservation level. The fields related to the materiality of the land will be considered from the inventory file and from this maps will be generated for the analysis in the two mentioned temporalities. The results are intended to show in percentage the buildings that maintain the land as a predominant material, as well as those in which this particular characteristic has been altered. The study through geo-reference maps will visually identify clusters and serve as a reference to the timing of appropriate intervention actions.
