Landsat and MODIS data for the Coleambally Irrigation Area

The Coleambally Irrigation Area study site is a rice based irrigation system located in southern New South Wales (NSW, Australia; 34.0034E, 145.0675S) which has been extensively used for time series remote sensing research. Over the Coleambally 17 cloud-free Landsat-MODIS pairs were available for the 2001–2002 austral (i.e., southern hemisphere) summer growing season. Each image is 43 km in the north-south (N-S) direction and 51 km in the east-west (E-W) direction; an overall area of 2,193 km2 comprised of 1720 columns by 2040 lines at 25 m resolution. All Landsat imagery are ETM+ acquired by Landsat-7. Coleambally is entirely in the E-W overlap of two adjacent paths in the Landsat World Reference-2 system (i.e., Paths/Rows 92/84 and 93/84) allowing for an ~8-day repeat cycle. A separate folder contains a binary image for masking a selection of irrigated paddocks used for evaluation of accuracy of blending algorithms in land cover specific areas as described in the following citation:
