#' Coleambally series of multispectral images
#' 
#' The dataset is made of 2 coarse-fine pairs of satellite images.
#' Coarse images are MODIS-like scenes and fine images are Landsat-like scenes.
#' Images cover an agricultural region in Australia called Coleambally.

#' MODIS Sinusoidal Tile Grid System
#' 
#' The land products are produced and distributed in adjacent 
#' non-overlapping tiles that are approximately 10 degrees square 
#' (at the equator). There are 460 non-fill tiles, tiles are 10 degrees
#' by 10 degrees at the equator. The tile coordinate system starts at 
#' (0,0) (horizontal tile number, vertical tile number) in the upper 
#' left corner and proceeds right (horizontal) and downward (vertical).

#' Landsat World Reference System - 2
#' 
#' Scene boundaries and tile coordinates for Landsat 4-8 images, where
#' centers are designated by PATH and ROW numbers. Polygons belong
#' to the descending (daytime) trajectory.
