The ORNL DAAC and the LBA DIS announce the release of three data sets associated with the LBA-ECO component of the Large Scale Biosphere- Atmosphere Experiment in Amazonia (LBA).
- LBA-ECO LC-24 Cadastral Property Map of Uruara, Para, Brazil: ca.1975. Data set prepared by R.T. Walker and M.M. Caldas. This data set contains a shapefile of a digitized map of the land parcel information of the original properties of the Uruara colonization site, Para, Brazil, acquired from the Instituto de Colonizacao e Reforma Agraria, (INCRA). The digital data were geo-referenced and projected to match the Universal Transverse Mercator projection (Zone 22 South, World Geodetic System 1984 datum).
- LBA-ECO LC-24 Historical Roads of the Legal Amazon: 1968-1993. Data set prepared by R.T. Walker, E.J. Reis, and M.M. Caldas. This data set contains ESRI shapefiles of historical federal and state roads in nine Brazilian states for the Legal Amazon: Amazonas, Para, Acre, Rondonia, Roraima, Tocantins, Amapa, Matto Grosso, and Maranhao, for the years 1968, 1975, 1981, 1985, 1987, and 1993 in South American 1969 geographic coordinate system projection.
- LBA-ECO LC-02 Hot Pixel Fire Indicator Data for Tri-national MAP Region: 2003-2006. Data set prepared by S. Vasconcelos and I.F. Brown. This data set provides hot pixel data, as an indicator of fires, that were detected by various satellites in the tri-national MAP region (Madre de Dios-Peru, Acre-Brazil, and Pando-Bolivia) in 2003, 2004, 2005, and 2006. Data were compiled from NOAH, GOES, AQUA, and TERRA satellites/instruments, and made available by the Centro de Previsao do Tempo e Estudos Climaticos (CPTEC) of the Instituto Nacional de Pesquisas Espaciais (INPE).
LBA is an international research initiative under the leadership of Brazil. The project focuses on the climatological, ecological, biogeochemical, and hydrological functions of Amazonia; the impact of land use change on these functions; and the interactions between Amazonia and the Earth system. The LBA-ECO component, which is funded by NASA, focuses on the question: "How do tropical forest conversion, regrowth, and selective logging influence carbon storage, nutrient dynamics, trace gas fluxes, and the prospect for sustainable land use in Amazonia?"
See the LBA Project page for further information about the study and to access associated data and documentation maintained by the ORNL DAAC.
The ORNL DAAC is a NASA-funded data center archiving and distributing terrestrial ecology and biogeochemical dynamics data. The LBA Data and Information System (LBA-DIS) has been developed by INPE with NASA's participation.
