The Burn Area Index (BAI) is generated from the Red and Near-IR bands, and measures the spectral distance of each pixel from a reference spectral point (the measured reflectance of charcoal). This index is intended to emphasize the charcoal signal in post-fire images. See Chuvieco et al. (2002) for details. This product is generated from the MODIS/MOD09GA surface reflectance composites.

烧伤面积指数(BAI)由红色和近红外波段产生,测量每个像素与参考光谱点(测得的木炭反射率)的光谱距离。这个指数的目的是强调火后图像中的木炭信号。详见Chuvieco等人(2002)。该产品是由MODIS/MOD09GA表面反射率合成物生成的。

代码:

var dataset = ee.ImageCollection('MODIS/MCD43A4_006_BAI')
                  .filter(ee.Filter.date('2018-04-01', '2018-06-01'));
var scaled = dataset.select('BAI');
var scaledVis = {
  min: 0.0,
  max: 100.0,
};
Map.setCenter(-7.03125, 31.0529339857, 2);
Map.addLayer(scaled, scaledVis, 'Scaled');
