Abstract
El estudio pretende relacionar las variaciones en las temperaturas locales en el distrito central del cantón de Naranjo, Alajuela, mediante el uso de imágenes Landsat 8 y Sistemas de Información Geográfica. Se realizó una vectorización de la cobertura del suelo y se compararon las áreas de las diferentes coberturas con las áreas de los rangos de temperatura obtenidos, mostrando una relación entre las temperaturas altas y las zonas urbanas y las temperaturas bajas y las zonas con vegetación. Mostrar las relaciones entre la cobertura y la temperatura es importante para establecer medidas de mitigación y adaptación efectivas ante los cambios climáticos, y así evitar efectos que van asocia-das a las zonas urbanas como lo son las islas de calor.
The study aims to relate the variations in local temperatures in the central district of Naranjo, Ala-juela, through the use of Landsat 8 images and Geographic Information Systems. A vectorization of the soil cover was carried out, and the areas of the different coverings were compared with the areas of the temperature ranges obtained, showing a relationship between high temperatures and urban areas and low temperatures and areas with vegetation. Showing the relationship between coverage and temperature is important to establish effective mitigation and adaptation measures in the face of climate changes and thus to avoid effects associated with urban areas such as the heat islands.
