dc.description | Continuous summit-to-sea maps showing both land features and shallow-water coral reefs have been completed in Puerto Rico and the U.S. Virgin Islands, using circa 2000 Landsat 7 Enhanced Thematic Mapper (ETM+) Imagery. Continuous land/sea terrain was mapped by merging Digital Elevation Models (DEM) with satellite-derived bathymetry. Benthic habitat characterizations were created by unsupervised classifications of Landsat imagery clustered using field data, and produced maps with an estimated overall accuracy of >75% (Tau coefficient >0.65). These were merged with Geocover-LC (land use/land cover) data to create continuous land/ sea cover maps. Image pairs from different dates were analyzed using Principle Components Analysis (PCA) in order to detect areas of change in the marine environment over two different time intervals: 2000 to 2001, and 1991 to 2003. This activity demonstrates the capabilities of Landsat imagery to produce continuous summit-tosea maps, as well as detect certain changes in the shallow-water marine environment, providing a valuable tool for efficient coastal zone monitoring and effective management and conservation. | en-US |
dc.description | Se elaboraron mapas de Puerto Rico y las Islas Vírgenes Estadounidenses que muestran la cobertura del suelo y el fondo en arrecifes de coral (“mapas cima-mar) con imágenes del año 2000 del Enhanced Thematic Mapper (ETM+) del satélite Landsat 7. Se fusionaron Modelos de Elevación Digital con batimetría satelital. Se caracterizaron hábitats bentónicos con clasificaciones “no supervisadas” de imágenes de Landsat, agrupando mediante datos de campo, y produciendo mapas con una precisión superior al 75% (coeficiente Tau >0.65). Estas caracterizaciones se combinaron con datos de Geocover-LC (uso /cobertura del suelo) para hacer los mapas. Comparando pares de imágenes mediante Análisis de Componentes Principales se logró identificar las zonas de cambios en los ambientes marinos en dos períodos: 2000 a 2001 y 1991 a 2003. Se demostró la capacidad de las imágenes del satélite Landsat para producir mapas continuos cima-mar y para detectar cambios en los ambientes marinos someros, proveyendo así una valiosa herramienta para el monitoreo, el manejo y conservación efectiva de la zona costera. | es-ES |
