Very high resolution satellite imagery for Bonaire; basis for land cover map

Very high resolution satellite imagery has been acquired for Bonaire and concerns very detailed ortho-rectified imagery from the Pleiades satellites. The Pleiades satellites were designed under the French-Italian ORFEO program (Optical & Radar Federated Earth Observation) in the early 2000’s. Pleiades 1A and 1B optical sensors provide panchromatic imagery with 50 cm resolution and multiresolution imagery in 4 spectral bands (blue, green, red and near-infrared) with 2m spatial resolution. To obtain cloud-free EO data for Bonaire is a quite difficult task and the final selection of imagery consisted of 3 scenes from different dates: 1) 8th of March 2016 for the Northern region; 2) 3rd of May 2014 for the Central region; 3) 28th of February 2014 for the Southern region.  On basis of these scenes a pan-sharpened mosaic has been created with a 50 cm resolution for the entire island of Bonaire including the coastal marine zone as shown below. This mosaic has also been used to digitize the coastline in more detail. The multispectral resolution data will be used as the basis for a new land cover / land use classification that can be used as a basis for further monitoring and spatial modelling of for example natural habitats and ecosystems and their services.
