To create this color composite, each raster dataset needs to be contained as individual bands within a single raster dataset. AVHRR: images can have daily coverage and are more reasonable for large projects, but can't detect small features. The composites were created using the ee.Algorithms.Landsat.simpleComposite() method with its default settings. The basic aim of these filters is to create a visual map of the area. The downside of this set of bands is that they tend to produce a hazy image.
