Modification of normalised difference water index (NDWI) to enhance open water features in remotely sensed imagery

Open access

Abstract

La presente investigación busca identificar el cambio del cauce del Río Amazonas entre los años 2015 a 2022 y los efectos del mismo mediante análisis y modelamiento de la dinámica del afluente, no solo sobre las riveras y llanuras aledañas, sino especialmente sobre el Municipio de Puerto Nariño. El municipio según lo documentado, desde el año 2020 se encuentra expuesto de forma directa al cauce, y los análisis conseguidos en la presente investigación, aportan a estudios en gestión de riesgos y planes de ordenamiento territorial que realicen planes de prevención sobre las áreas identificadas las cuales de conformidad con el comportamiento natural del Río, a futuro serán zonas erosionadas, que presenten constantes desprendimientos de tierra y desestabilicen árboles de gran magnitud que representen un peligro para las poblaciones aledañas. La presente investigación hace uso de los Sistemas de Información Geográfica aplicados a imágenes satelitales Landsat 8 con nivel de procesamiento 2 y el Índice de Agua de Diferencia Normalizada Modificado MNDWI, cuya clasificación de cuerpos de agua sobre cualquier otra cobertura es más efectiva que la clasificación que se logra con el índice NDWI, lo que facilitó la identificación del cauce para el modelamiento de la dinámica en los años propuestos

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
