LBA-ECO LC-10 ORTHORECTIFIED LANDSAT ETM+ DATA FOR LEGAL AMAZON: 1999-2001
Get Data

Summary:

This data set includes orthorectified Landsat ETM+ scenes across the Legal Amazon region. At least one scene is provided for each spatial tile, representing the most cloud-free retrievals from mid-1999 through late 2001 (Fig. 1). Dates are therefore not continuous but include scenes from July 8, 1999 to November 13, 2001. Data have been atmospherically corrected and orthorectified.

Data files (and format) included for each scene are: six multispectral bands (tif), two thermal bands (tif), one panchromatic band (tif), two preview files (jpg), and one metadata file (txt). The individual Geotiff files have been g-zipped and subsequently all of the files for a scene have been g-zipped together for ordering convenience.

Implementation of the LBA Data and Publication Policy by Data Users:

The LBA Data and Publication Policy [http://daac.ornl.gov/LBA/lba_data_policy.html] is in effect for a period of five (5) years from the date of archiving and should be followed by data users who have obtained LBA data sets from the ORNL DAAC. Users who download LBA data in the five years after data have been archived must contact the investigators who collected the data, per provisions 6 and 7 in the Policy.

This data set was archived in August of 2007. Users who download the data between August 2007 and July 2012 must comply with the LBA Data and Publication Policy.

Data users should use the Investigator contact information in this document to communicate with the data provider. Alternatively, the LBA Web Site [http://lba.inpa.gov.br/lba/] in Brazil will have current contact information.

2. Data Characteristics:

This data set includes orthorectified Landsat ETM+ scenes across the Legal Amazon region. At least one scene is provided for each spatial tile, representing the most cloud-free retrievals from mid-1999 through late 2001. Dates are therefore not continuous and include scenes from July 8, 1999 to November 13, 2001.

Data files (and format) included for each scene are: six multispectral bands (tif), two thermal bands (tif), one panchromatic band (tif), two preview files (jpg), and one metadata file (txt). The individual Geotiff files have been g-zipped and subsequently all of the files for a scene have been g-zipped together for ordering convenience.

There are several tiles that have 2 scenes, that is, there are some path/row combinations with more than one retrieval for the same area, but from different dates. The following path/row combinations have2 scenes each: p3r61, p224r65, p231r60andp231r62.

Each zipped data directory is constructed from a concatenation of path + row + date (e.g. Path_001/Row_061/p001r61_7x000914). The final 6 digits indicate year=00 (i.e. 2000), month=09, day=14.

3. Data Application and Derivation:

These data were collected from the Landsat ETM+ sensor. Due to their high resolution, they are especially appropriate for small-scale/mesoscale land cover change studies.

4. Quality Assessment:

Data are atmospherically corrected and orthorectified. The individual images should be highly useful as they include very little cloud cover, but care should be used if they are mosaicked together since retrieval dates vary.

5. Data Acquisition Materials and Methods:

Original Landsat scenes were acquired from Eros Data Center (EDC).

6. Data Access:

These data are available through the Oak Ridge National Laboratory (ORNL) Distributed Active Archive Center (DAAC) or the EOS Data Gateway.
