| description | Ecuadorian archaeology has focused especially on understanding the past of the Coast and Highlands regions, leaving the Amazon region behind, despite having a historical past of equal importance. The Upano Culture is the main pre-Columbian human settlement that inhabited the Upano valley, in what is now the Morona canton - southeast of Ecuador, whose archaeological sites are located on both banks of the Upano River; one of these is the mound complex known as La Esperanza. Due to urban sprawl and lack of protection by the responsible institutions, the conservation of these complexes is at risk. An alternative to collect information that allows to show the current state of the archaeological heritage is the use of UAVs. The present work aims to apply aerial photogrammetry with UAV to determine the state of conservation of the La Esperanza archaeological complex. Using a combination of GNSS positioning and the Structurefrom Motion technique, photogrammetric products were obtained that showed a deterioration of the archaeological site, where only 28.6% of the original complex exists today. Thanks to advances in geosciences, UAVs can generate accurate and low-cost cartographic information that can be used as input for archaeological work. |

Ecuadorian archaeology has focused especially on understanding the past of the Coast and Highlands regions, leaving the Amazon region behind, despite having a historical past of equal importance. The Upano Culture is the main pre-Columbian human settlement that inhabited the Upano valley, in what is now the Morona canton - southeast of Ecuador, whose archaeological sites are located on both banks of the Upano River; one of these is the mound complex known as La Esperanza. Due to urban sprawl and lack of protection by the responsible institutions, the conservation of these complexes is at risk.

La arqueología ecuatoriana se ha centrado especialmente en comprender el pasado de las regiones Costa y Sierra, dejando rezagada a la Amazonía, a pesar de guardar un pasado histórico de igual importancia. La cultura Upano es el principal asentamiento humano precolombino que habitó en el valle del Upano, en lo que hoy es el cantón Morona – sureste del Ecuador, cuyos sitios arqueológicos se encuentran en ambas márgenes del río Upano; uno de estos, es el complejo de montículos conocido como La Esperanza. Debido a la expansión urbana y falta de protección por parte de las instituciones responsables, la conservación de estos complejos se encuentran en riesgo. Una alternativa para levantar información que permita evidenciar el estado actual del patrimonio arqueológico, son los UAV (Unmanned Aerial Vehicle). El presente trabajo tiene por objetivo aplicar fotogrametría aérea con UAV para determinar el estado de conservación delcomplejo arqueológico La Esperanza. Mediante la combinación de posicionamiento GNSS y la técnica Structure from Motion se obtuvieron productos fotogramétricos que demostraron un deterioro del sitio arqueológico, donde solo el 28.6% del complejo original existe actualmente. Gracias al avance de las geociencias, los UAV permite generar información cartográfica precisa y de bajo coste que sirven de insumos para trabajos arqueológicos.
