SAFARI 2000 MODIS 500-m Burned Area Products, Southern Africa, Dry Season 2000

The SAFARI 2000 project was selected as the first regional test for a prototype regional 500 m MODIS burned area product. The MODIS burned area product maps the 500 m location and approximate day of burning using a change detection algorithm based on a bi-directional reflectance model-based expectation method applied to the MODIS near-infrared and shortwave infrared bands (Roy et al., 2002). The algorithm was applied to recently reprocessed 500 m daily MODIS land surface reflectance data to produce burned area data sets for all of southern Africa for 2000 forward. This archived data set contains MODIS 500 m burned area products for two dry season months (July and September 2000).Burned area products are spatially explicit data sets that describe the approximate day of burning at 500 m resolution for all of southern Africa south of the Equator, including Madagascar. The burned area maps are compressed GeoTiff files. Several text files are included in the compressed files to aid ENVI (Research Systems, Inc.) users, including ENVI header files and ENVI density slice files. The data set also includes a projection parameters file.The MODIS burned area data set was validated using a methodology based upon the interpretation of multitemporal Landsat Enhanced Thematic Mapper plus (ETM+) data as described in Roy et al. (in press).

SAFARI 2000项目被选为首个区域测试原型500米MODIS燃烧区域产品的区域试验。MODIS燃烧区域产品通过基于双向反射模型期望方法的改变检测算法，应用于MODIS近红外和短波红外波段（Roy et al., 2002），以绘制500米分辨率下的燃烧位置和大约的燃烧日期。该算法应用于最近重新处理过的500米每日MODIS地表反射率数据，以生成2000年及以后整个南部非洲的燃烧区域数据集。此存档数据集包含两个干季月份（2000年7月和9月）的MODIS 500米燃烧区域产品。燃烧区域产品是空间显式数据集，描述了赤道以南南部非洲所有地区在500米分辨率下的大约燃烧日期，包括马达加斯加。燃烧区域地图是压缩的GeoTiff文件。压缩文件中包含几个文本文件，以辅助ENVI（Research Systems, Inc.）用户，包括ENVI头文件和ENVI密度切片文件。数据集还包括投影参数文件。MODIS燃烧区域数据集的验证采用了基于多时相Landsat增强型专题制图仪加（ETM+）数据解释的方法，具体方法见Roy et al.（待发表）。
