The ORNL DAAC and the LBA DIS announce the release of three data sets associated with the LBA-ECO Land Use-Land Change (LC-01) team of the Large Scale Biosphere-Atmosphere Experiment in Amazonia (LBA).
These LC-01 data sets were prepared by Stephen Walsh, Richard Bilsborrow, and Brian Frizzelle:
- LBA-ECO LC-01 City, Community, and Road Maps, Northern Ecuadorian Amazon: 1990-2002. This data set contains the boundaries of the four major cities in the Northern Ecuadorian Amazon, as well as locations of the primary communities in the colonist settlement study area in the northern Oriente of Ecuador, and locations of the road network for the northern Oriente of Ecuador, circa 2002.
- LBA-ECO LC-01 National, Provincial, and Park Boundaries, Ecuador. This data set contains the national and provincial boundaries of Ecuador as well as the boundaries of two national parks: the Cuyabeno Wildlife Reserve and the Yasuni National Park.
- LBA-ECO LC-01 Hydrography, Morphology,Edaphology Maps, Northern Ecuadorian Amazon. This data set provides map images of hydrographic, morphologic, and edaphic features for the northern Amazon Basin in eastern Ecuador. The hydrographic data are available at two scales based on the 1:50,000 and 1:250,000-scale topographic source maps that were generated in 1990 and 1993, respectively. Morphological and edaphological data were digitized from a 1:500,000 map published in 1983.
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.
