Ítem Metodología para la publicación estandarizada de firmas espectrales en la clasificación de coberturas del sueloValbuena Gaona, Martha Patricia; Herrera Escorcia, José LuisSpectral signatures are graphs that show the reflectance of objects in the presence of light. There are particularities in the shape of the spectral curve due to the physical and chemical composition of the different soil coverings. Therefore, the inclusion of spectral signatures in object-based classification represents a determining factor in the accuracy of classifications. The definition of a standard for the publication of spectral signatures represents an advance in the field of remote sensing as it facilitates researchers to access the results of other studies, verifying their quality and accuracy, making possible the formation of a national library of spectral signatures. Through this project, the development of a methodology to standardize the publication of spectral signatures in the classification of soil coverings is proposed, taking into account the international standards proposed by the OGC, through the Sensors Web Enabling Framework - SWE, which allows developers to make information captured by different instruments detectable, accessible and usable via the Web. The research will be carried out in three stages, the first includes the bibliographic review and regulations related to the standardization of spectral signatures at the national and international levels. Subsequently, a standard metadata is defined based on the OGC parameters, identifying the representative parameter settings required for the classification of soil coverages. Finally, the proposed methodology requires field validation, where fields defined in the metadata shall be verified to be representative from Machine Learning methods.Ítem Propuesta metodológica para la estandarización e incorporación de información Ráster y Lidar a la Plataforma del sistema de información territorial para la construcción y operación - SitcoValbuena Gaona, Martha Patricia; Herrera Escorcia, José LuisISA Intercolombia has a platform in which geographic, alphanumeric and legal data related to ISA assets are entered. Currently, the platform has standardized vector information through geographic metadata generated from NTC 4611 of 2014. Through this methodological proposal, the standardization and incorporation of raster and LiDAR information to the SITCO platform is proposed, taking into account the criteria of the Open Geospatial Consortium, the Agustín Codazzi Geographical Institute and the American Association of Photogrammetry and Remote Sensors.
