SAFARI 2000 GLOBAL BURNED AREA MAP, 1-KM, SOUTHERN AFRICA, 2000
Get Data

Summary:

The Global Burned Area 2000 initiative (GBA2000) was launched by the Global Vegetation Mapping Unit of the Joint Research Centre of the European Commission, in partnership with several other institutions, to develop reliable and quantitative information on the global magnitude and spatial distribution of biomass burning. The objective of GBA2000 was to produce a map of the areas burned globally for the year 2000, using the medium resolution satellite imagery provided by the SPOT-VEGETATION (VGT) system and to derive statistics of area burned per type of vegetation cover.

A subset of the global GBA20000 map was prepared for SAFARI 2000 to map the area burned in sub-Saharan Africa during 2000 on a monthly basis using VGT imagery at 1 km spatial resolution. Burned areas were identified with a classification tree, relying only on the near-infrared channel of VGT. The data used in this work are in the S1 daily synthesis format, i.e. the data are radiometrically calibrated, precisely geo-located, and corrected for atmospheric effects.

The data are binary image files of area burned, BSQ format in geographic projection. There is one file for each month of 2000 and one file for all of the year 2000. There is also a comma-delimited ASCII text file that provides geographic coordinates (latitude and longitude) of the center of each pixel indicated as a burned area for all of 2000.

Data Format:

The data are binary image files of area burned, BSQ format in geographic projection. There is one file for each month of 2000 and one file for all of the year 2000. The data files are compressed (.zip). Each zip archive contains a monthly or annual .bsq image file and the associated .hdr header file. The zip files are named as follows:

Companion Files

There is also a companion comma-delimited ASCII text file (africa_gba2000-total_csv.zip) that provides geographic coordinates (latitude and longitude) of the center of each pixel indicated as a burned area for all of 2000. Please note that this file has been altered from that which is distributed on the GBA2000 web site. The coordinates of the location of each pixel within the SPOT VEGETATION S1 global product are also given in the original version. This information has been removed to reduce the file size.

In addition, there are several companion spreadsheet files that provide additional data derived from SPOT-VEGETATION imagery. These are: gba2000_country_month_totals.csv [burned area (km2) per country and month for the year 2000]; gba2000_country_month.csv [comma delimited burned area (km2), number of scars (all clusters and individual pixels), average size of the scar (km2), % of total area of country burned (shown for the year 2000 synthesis only)]; and gba2000_country_vegetation_2000.csv [burned area (km2), number of scars, average burn scar size, and % of the category burned per country and broad vegetation type for the year 2000].

Additional information about SPOT-VEGETATION data and creation of the burned area product for Sub-Saharan Africa is found in the companion file: http://daac.ornl.gov/daacdata/safari2k/remote_sensing/spot_veg_burned/comp/spot_veg_burned_readme.pdf.
