After an exploratory search of the USGS GLOVIS gateway (http://glovis.usgs.gov/) that yielded more than 500 potential images from Landsat missions 4, 5 and 7 for all test cases with different degree of cloud cover, a total of 284 Landsat images were selected. The selection was intended to maximize high quality image radiometry following two criteria: a) including images with less of 20% cloud cover; and b) excluding images with low Sun height that cause strong presence of self-cast shadows due to terrain relief.\r\n\r\nIndex shapefile is available for download.
