Due to the extension of the Brazilian Amazon (approximately 5,000,000 km2), as well as remote access, remote sensing data have an important role in characterizing land use/land cover change. Several studies have addressed the problem of land use/land cover change, deforestation, and secondary succession forest mapping in the Brazilian Amazon using high resolution optical remote sensing data. During the last decade, several orbital platforms have provided different sources of information for global studies. Several international and Brazilian led studies focused on the Amazon Basin are: the Global Rain Forest Mapping (GRFM) project that covered the Amazon Basin with L band radar data on two hydrological conditions; the Global Land Cover 2000 (GLC 2000) project that is providing, for the year 2000, a harmonized land cover database over the whole globe, but with some emphasis in areas considered as deforestation hotspots; the Large Scale Biosphere Atmosphere (LBA) experiment in Amazonia that aims to study the role of the Amazon region as part of the Earth system and to evaluate the influence of land-use and climate change in biological, chemical, and physical processes. The purpose of this work is to organize a global remote sensing database for the LBA project. The data to be available in this database are: (1) Moderate Resolution Imaging Spectroradiometer (MODIS) monthly composites, (2) Japanese Earth Remote Sensing Satellite (JERS) mosaics, (3) Shuttle Radar Topography Mission (SRTM), (4) Aerial videography mosaics, etc. It will also include the PRODES deforestation surveys, IBGE Vegetation Map, Floodplain maps. The information in this database will be continuously updated by new sensor images such as the three sensors on CBERS satellite and by new results generated from this dataset.
