LC-08 (Moore / Nobre)

LBA Dataset ID:

LC08_EOS_Maps

Originator(s):

BLISS, N.

Point(s) of Contact:

ORNL DAAC User Services Office Oak Ridge National Laboratory Oak Ridge, Tennessee 37 (ornldaac@ornl.gov)

Dataset Abstract:

This dataset includes maps of soil classifications and vegetation classifications at various level of detail for Brazil. In addition there is a land cover classification map for all of South America. The soils and vegetation maps were digitized from maps published by Brazilian government agencies in the 1980s while the land cover map for all of South America was derivied from National Oceanic and Atmospheric Administration (NOAA) Advanced Very High Resolution Radiometer (AVHRR) data over the time period 1987 through 1991. Further information can be obtained from Woods Hole Research Center, Woods Hole Massachusetts.

Data Characteristics (Entity and Attribute Overview):

Data Characteristics:

Data are presented as netCDF files (*.nc) and each data file has an accompanying text file which has the same file name with aux appended to the end. In total there are 7 netCDF files (3 files for the soil maps, 3 for the vegetaton maps and one land cover map) and 7 text files.





Soil maps are available in 3 NetCDF files that originated from EOS-Webster.



The data resolution is 0.0083 degrees (nominally 1 km). Data are part of the Soils Map of Brazil Variable in the LBA / South American Data Collection. Data are provided by the Woods Hole Research Center but are originally from the Instituto Brasileiro de Geografia e Estatistica (IBGE). Data represent the year 1981, based on the publication date. See citation in the auxiliary files provided.

Vegetation maps are available in 3 NetCDF files that originated from EOS-Webster



These maps are digital versions of the MAPA DE VEGETACAO DO BRASIL (IBGE, 1988), which was digitized at the U.S. Geological Survey's (USGS) EROS Data Center, Sioux Falls, South Dakota. Data are classed into either 13 or 59 classes and are generalizations of the major vegetation classes. A 6-class overprint holding were also created from the original data. Generalized

classes were determined from the original subheadings on the original published map which was used use to digitize the data set. Overprint classes are used to describe areas which are best described by a combination of two classes, one from the major classification and the other from the overprint classification. Overprint classes were originally displayed with special symbols printed over major classification shades on the original map. For instance, a series of stipple marks or hash marks may have been printed on top of major class shades to represent areas which had characteristics from the major classification as well as the overprint classification. The overprint classifications are also referred to as subclasses in the original data.

Data Application and Derivation:

Maps are a useful reference point reflecting the land use and land cover status at this point in time.

Quality Assessment (Data Quality Attribute Accuracy Report):

Quality Assessment:

The information contained in the soils maps are highly generalized. The scale is very small and there is not soil uniformity in large expanses. The map units are predominantly associations of several soil types; of these only the principal ones are specified within each mapunit. The naming of each map unit is given according to the areal importance of those soil types that are contained in each association. Soil types with little areal importance are not listed. The composition of the map units is not entirely consistent across the full range of the map, nor is the precision of the map unit boundaries uniform.

Process Description:

Data Acquisition Materials and Methods:

Soils Maps:

These data were originally acquired from Woods Hole Research Center (http://terra.whrc.org/science/tropfor/setLBA.htm) and modified for incorporation in the UNH EOS-WEBSTER system. The subset for the LBA study region was downloaded from EOS-WEBSTER and is provided here as part of the LBA data archive.
