This study uses artificial intelligence to comprehensively evaluate digital elevation models (DEMs), specifically SRTM, AlosPalsar, and ASTER, in the Moquegua region of Peru. Three recognized standards were used to evaluate the positional accuracy of DEMs: EMAS, NMAS, and NSSDA. The DEMs were also assessed through correlation, the coefficient of determination (R2) and the Bland-Altman Graph, which allowed us to understand and visualize the relationship and agreement between the elevations extracted from the DEMs and the altimetric control network of the national chart of Peru at a scale of 1:25000. The correlation and R2 revealed a solid relationship and a high degree of explanation for the variability of the elevations observed by the MDEs. The Bland-Altman plots confirmed the agreement between the elevations predicted by the MDEs and those observed at the points of the altimetric contr...

Las actividades antrópicas y los procesos de urbanización de las ciudades con el recorrer del tiempo, han intensificado los cambios de uso y cobertura de la tierra aceleradamente, ocasionando diversos impactos ambientales percibidos en los informes, mesas de trabajo e investigaciones locales, nacionales e internacionales. Los estudios de cambios de uso y cobertura de la tierra son imprescindibles para comprender los procesos de cambios naturales y antrópicos, además de analizar integralmente el medio ambiente y la sociedad, constituyéndose en la actualidad una importante herramienta de orientación para la toma de decisión en el ordenamiento territorial y ambiental. El objetivo del presente estudio es analizar el espacio temporal de cambios de uso y cobertura de la tierra en la ciudad de Moquegua y el pueblo de Samegua de 1955 y 2018, emplazadas en una zona de 13 200 hectáreas, ut...
