Castellanos-Quiroz Héctor Mauricio Ramírez-Daza Yulia Ivanova Ingeniería Open pit mining images fusion spectral indices fusión de imágenes This article aims to present the results of the application of different proposed spectral indices and image fusion techniques for the detection of open-pit mining zones, located to the north-east of Antioquia, Colombia; having as reference mining and no mining zones samples obtained from visual characterization of pictorial-morphological properties of the open-pit mining zones in the study area. This research used high resolution (UltraCam-D y RapidEye) and medium resolution (Landsat 8 LDCM) imagery, where the latter was defined as the main input for the application of the spectral indices and image fusion techniques. The development of the proposed methodological design and the statistical analysis of the images, presented the Brovey transformed image fusion technique —on its band 2—as the one with the highest discriminant potential for open-pit mining zone; the classification of the results were determined between the thresholds of pixel values from 0.3225 —defined as the discriminant breakpoint—to the maximum value of the mining group samples, corresponding to 0.5237. 2017 artículo científico 0012-7353 https://www.redalyc.org/articulo.oa?id=49650911005 https://www.redalyc.org/journal/496/49650911005/ https://www.redalyc.org/journal/496/49650911005/html/ https://www.redalyc.org/journal/496/49650911005/49650911005.epub https://www.redalyc.org/journal/496/49650911005/movil es http://www.redalyc.org/revista.oa?id=496 Dyna application/pdf Universidad Nacional de Colombia Dyna (Colombia) Num.201 Vol.84 |
