| Abstract | A new methodology is being proposed for the mapping of all Brazilian coastal reefs, using TM Landsat and HRV SPOT images. This is a joint effort involving researchers from Diretoria de Áreas Protegidas/Ministério do Meio Ambiente, Programa HIDRO/INPE and Projeto Recifes Costeiros/UFPE-IBAMA-BID. This methodology is built upon the experience gathered during the mapping of coastal reefs from na environmental protected area called Costa dos Corais, located between the States of Pernambuco and Alagoas (Northeast Brazil). Initially, remote sensing images were classified using segmentation techniques to identify and map the following themes: 1)water; 2)sand flat environments; 3)shoals; 4)"breaker zone"; 5)river plume; 6)beach; 7)intertidal and shallow subtidal reefs; and 8)reef surfaces partially covered by sediments. Segmentation of LANDSAT bands TM1, 2 e 5 reached the highest mapping precision (74). Segmentation of band TM1 followed by the classification of bands TM1, 2 e 5 resulted in the most cost effective mapping (69), demanding less computer time and interaction with the analyst. However, visual interpretation of TM LANDSAT images allowed the identification of most themes and showed to be the most efficient way to map the reefs. Based on the above results, a mapping strategy will be applied where TM LANDSAT images will be appropriately filtered and resampled to the best spatial resolution possible and visually interpreted. Whenever possible, local managers will be invited to be trained on GIS and mapping techniques using digital images. This effort aims at improving the coastal zone management skills of people involved in the management of reef protected areas. |
