Desarrollo de una herramienta para la valoración del suelo rural del cantón Chordeleg, Ecuador

Abstract

The aim of this degree project was to develop an automated tool for rural land valuation in the Chordeleg canton, Azuay Province, Ecuador, in order to improve the efficiency and updating of cadastral management. The methodology was based on the delineation of Physical Homogeneous Zones (PHZ) through the integration of physical, productive, and accessibility variables of the territory, using a multicriteria analysis approach in accordance with the guidelines established in the Land Use and Management Plan (PUGS). Subsequently, land valuation was carried out by relating a multicriteria index to rural market data through the application of an exponential regression model. In addition, an automated model was designed in QGIS using Model Designer, enabling the development of a reproducible workflow for the generation and updating of spatial information. The results show that the developed tool allows the automated generation of PHZ, reducing processing times and manual intervention, thereby increasing the efficiency of the cadastral process. However, the automation of Geoeconomic Homogeneous Zones (GHZ) was not fully achieved due to the limited availability of market information, which required manual adjustments during the final valuation stage. In conclusion, the proposed model constitutes a replicable methodological tool that can be improved through greater data availability and independent statistical validation processes.
