Edificaciones en tierra intervenidas en la campaña de mantenimiento de San Roque, Cuenca, Ecuador. Métodos visuales en la fase de diagnóstico
(Coordinación de Publicaciones y Difusión de FADA/UNA, 2016) Achig Balarezo, Maria Cecilia; Barsallo Chavez, Maria Gabriela; Briones Orellana, Juan Carlos; Piedra Landivar, Victor Cesar
The maintenance campaign carried out in the San Roque neighborhood at the beginning of 2014, promoted by the vlirCPM1 project and the FAUC2, concluded with an execution time considerably greater than that estimated in the diagnostic phase. This research aims to evaluate the methodology applied and find the factors that could cause this difference between the planned and executed, based on new knowledge of experts in the area of evaluation and diagnosis, it is expected that these additions to the methodology will allow more accurate estimate in subsequent campaigns.
Heritage building’s condition at maintenance campaign in San Roque, Cuenca - Ecuador
(CRC PRESS/BALKEMA, 2016-09-13) Achig Balarezo, María Cecilia; Barsallo Chavez, María Gabriela; Briones Orellana, Juan Carlos; Cardoso Martinez, Fausto Adrian
The condition assessment of heritage buildings in the Historic Center of the city of Cuenca, Ecuador (World Heritage City), which is an essential element within the process of conservation, has historically been done in a rather subjective manner. This research project’s objective is to present a methodology that contributes to the determination, in an objective manner, of the building’s condition through the damage register. The information and experience obtained from the maintenance campaign in a traditional neighborhood in Cuenca, San Roque, is used as input. This project was a vlir CPM (City Preservation Management) initiative. It took place in 2014 with the support of among others the University of Cuenca, the Municipality and the local state government. Currently the results of the maintenance campaign are being evaluated. With the gathered information, it is possible to generate comparative analyses and determine the building’s condition, with its conservation as its aim.

Procesos de clasificación supervisados como herramienta de monitoreo del patrimonio cultural edificado
(Servicios Académicos Intercontinentales S.L., 2018) Briones Orellana, Juan Carlos
The Historic Center of Santa Ana de los Ríos de Cuenca was incorporated in 1999 to the UNESCTO World Heritage List. However, the absence of conservation policies has led to the lost of the heritage values on which the listing criteria of Cuenca are based. In this respect, this research proposes to use a supervised classification method known as Support Vector Machines (SVM) to determine heritage elements that need to be monitored at a territorial scale. The results have shown a real possibility to control different elements accurately with a low computational load.
Strategies for the management of built heritage linked to maintenance and monitoring. Case study of the San Roque neighborhood, Cuenca, Ecuador
(International Society for Photogrammetry and Remote Sensing, 2017) Amaya Ruiz, Jorge Alberto
The rehabilitation of heritage sites, as well as the implementation of monitoring and control strategies is fundamental for its conservation. In the case of Cuenca, a World Heritage City, a maintenance campaign in the traditional neighborhood of San Roque was carried out in 2014. The objective was to undertake maintenance actions on roofs and façades as well as on elements at risk. The campaign process was developed keeping in mind the cycle or phases of preventive conservation: anamnesis, diagnosis, therapy and control (ICOMOS, 2003). At the end of the maintenance campaign an impact assessment was undertaken and monitoring tools were handed out to the community in order to strengthen the citizen participation in the preservation of built heritage. The experience of the maintenance campaign unveiled a series of lessons that have been evaluated in the present investigation, being the main objective the strengthening of the processes of governance and documentation through the formulation of strategies inherent to the maintenance of heritage buildings. In this process it is shown that the participation of citizens is a strategic factor for the sustainable development of maintenance campaigns, which allow for the preservation of historical sites for future generations.

SUPERVISED CLASSIFICATION PROCESSES for the CHARACTERIZATION of HERITAGE ELEMENTS, CASE STUDY: CUENCA-ECUADOR
(COPERNICUS GMBH, 2017-08-28) Briones Orellana, Juan Carlos; Heras Barros, Veronica Cristina; Sinchi Tenesaca, Edison Roman
The proper control of built heritage entails many challenges related to the complexity of heritage elements and the extent of the area to be managed, for which the available resources must be efficiently used. In this scenario, the preventive conservation approach, based on the concept that prevent is better than cure, emerges as a strategy to avoid the progressive and imminent loss of monuments and heritage sites. Regular monitoring appears as a key tool to identify timely changes in heritage assets. This research demonstrates that the supervised learning model (Support Vector Machines - SVM) is an ideal tool that supports the monitoring process detecting visible elements in aerial images such as roofs structures, vegetation and pavements. The linear, gaussian and polynomial kernel functions were tested; the lineal function provided better results over the other functions. It is important to mention that due to the high level of segmentation generated by the classification procedure, it was necessary to apply a generalization process through opening a mathematical morphological operation, which simplified the over classification for the monitored elements.
