| description |
This paper proposes a semi-automated method to study the fluvial dynamics of large rivers using multi-temporal geographic object-based image analysis (GEOBIA), which provides direct interoperability with geographic information systems, allows quantifying the variation of existing landforms, and is efficient in terms of computing time. The method is applied to the dynamics of the Amazon River, which has provoked a conflict between Peru and Colombia for being the borderline that separates both countries. The results obtained show the repercussions on its surface such as changes in sand islands and erosion, as well as the dynamics at the channel bottom during the 1989–2015 period caused by the sediment load and thalweg movement. These results are verified against data collected on field, finding 99.2 % accuracy between estimates and actual figures. |

El método brinda interoperabilidad directa con los sistemas de información geográfica, permite la cuantificación de la variación de las formas en superficie existentes y es eficiente en tiempo de cómputo. Los resultados obtenidos con esta metodología se verifican con datos tomados en campo. La metodología se aplica a la dinámica del río Amazonas, que ha generado conflicto entre Perú y Colombia debido a que el río fue establecido como la línea limítrofe que separa estos dos países. Los resultados muestran las repercusiones en superficie en cuanto a los cambios en las islas de arena, la erosión y la dinámica en el fondo del canal durante el período 1989-2015, causada por la carga de sedimentos y el movimiento del thalweg. En la validación con el estudio de campo se encontró un 99,2% de exactitud entre lo estimado y lo existente.Uma metodologia semi-automática é proposta para fazer este trabalho para o estudo da dinâmica fluvial de grandes rios, por meio da análise multitemporal de imagens de satélite com base em objetos geográficos (GEOBIA).

Os resultados obtidos com esta metodologia verificam-se com os dados obtidos no campo. A metodologia é aplicada à dinâmica do rio Amazonas que têm gerado conflitos entre o Peru e a Colômbia, porque o rio Amazonas foi estabelecido como a linha de fronteira que separa estes dois países. Os resultados revelam as repercussões na superfície referente às mudanças nas ilhas de areia, a erosão e a dinâmica no fundo do rio durante o período 1989-2015, causada pela carga de sedimentos e pelo movimento da thalweg. Na validação com o estudo de campo, achou-se uma precisão de 99,2% entre o que foi estimado e o que existia.application/pdfspaspaUniversidad Pedagógica y Tecnológica de Colombiahttps://revistas.uptc.edu.co/index.php/perspectiva/article/view/9377/9905Derechos de autor 2020 Perspectiva Geográficahttp://purl.org/coar/access_right/c_abf133http://purl.org/coar/access_right/c_abf2Perspectiva Geográfica; Vol. 25 Núm. 1 (2020); 77 - 98Perspectiva Geográfica; Vol. 25 Núm. 1 (2020); 77 - 98Perspectiva Geográfica; v. 25 n. 1 (2020); 77 - 982500-86840123-3769GEOBIASatellite imagesFluvial borderAmazon RiverGEOBIAImágenes satelitalesFrontera fluvialRío AmazonasGEOBIAImagens de satéliteFronteira fluvialRio AmazonasMulti-temporal analysis of the Peru-Colombia fluvial border by satellite images analysis based on geographical objects during the period 1989-2015Análisis multitemporal de la frontera fluvial entre Perú y Colombia mediante análisis de imágenes satelitales basado en objetos geográficos durante el período 1989-2015Análise multitemporal da fronteira fluvial entre Perú e a Colômbia mediante analise de imágens satelitais baseado em objetos geográficos durante o período 1989-2015info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6632http://purl.org/coar/resource_type/c_2df8fbb1info:eu-repo/semantics/publishedVersionhttp://purl.org/coar/version/c_970fb48d4fbd8a216http://purl.org/coar/version/c_970fb48d4fbd8a85Quiroga Olarte, Leidy JohannaBohórquez, Martha PatriciaSanta Guzmán, Luis Fernando001/13167oai:repositorio.uptc.edu.co:001/131672025-07-18 11:41:19.468metadata.onlyhttps://repositorio.uptc.edu.coRepositorio Institucional UPTCrepositorio.uptc@uptc.edu.co |
