                         spatial resolution remote sensing data for the Marine National 
                         Park in the Abrolhos Coral Reef Bank (ACRB). Imagery of the 
                         WorldView2 (WV02) orbital sensor, concomitant with field 
                         observations, was used. The imagery was passed through routines of 
                         geometric and atmospheric correction, and ws also corrected for 
                         sunglint and water column interference. Due to limitations in 
                         water column corrections, bottom reflectance was used only at 478 
                         nm. The resulting map had an accuracy of 88.2% with a Kappa index 
                         of 0.8 was considered satisfactory for the four thematic classes 
                         used: Reef, Sand, Macroalgae, and Inter-reef areas. The isolated 
                         reefs, locally known as chapeir{\~o}es, covered an area of 
                         approximately 22 km2 that corresponds to 12.4% of the total area. 
                         Chapeir{\~o}es were distributed in almost all the studied area, 
                         formed by patches with different sizes and concentration of reefs. 
                         Macroalgae constituted the most abundant benthic functional type 
                         in the scene and concentrated around the Archipelago and 
                         inter-reef areas. Further work regarding a more extensive in situ 
                         data collection to conclusively describe the benthic communities 
                         and their spectral behavior, as well as water column constituents 
                         and bathymetric surveys are recommended to improve satellite 
                         mapping of the bottoms types in the ACRB. More ground control 
                         points are still required for a more robust validation of the 
                         bottom type map.",
