Habitat composition and coverage mapping in La Parguera , Puerto Rico using AVIRIS and IKONOS imagery

Remote sensing techniques have become an invaluable tool in the assessment of coastal habitat coverage mapping. The present project intended to first, analyze the relationship of spectral and spatial resolution on the outcome of supervised classifications by using IKONOS multispectral and AVIRIS hyperspectral images. Secondly it was intended to analyzer the gradient of habitat coverage from toward the shelf edge of La Parguera keys. Spatial resolution resulted on accurate class definition over higher spectral information, although equal number of classes was mapped with both AVIRIS and IKONOS imagery. Sea grass beds dominate the coastal portions of La Parguera with an increase on reef habitats toward the shelf edge. In general remote sensing techniques when applied to coastal ecosystem assessment analysis are valuable but extensive field work still is needed.
