Target The Coleambally Irrigation Area (CIA) is an irrigated agricultural site, which is part of the A$1.5 billion per year irrigation industry of southeastern Australia. Principal summer crops (November – April) are rice, soybeans, and maize (corn). Wheat, oats and barley are grown over winter (May – October). Pasture for grazing is grown in both seasons. The CIA is a major contributor to the 1.5 million tonnes of rice yield generated per year in the region.

Data acquired every 8 days The CIA lies completely within the east-west overlap of two Landsat-7 scenes. Specifically they are Path 093 and Row 084 (the western scene) and Path 092 and Row 084 (the eastern scene). This means L7 and EO1 data is acquired every 8 days. Actually, due to orbital parameters, there are either 7 or 9 days between consecutive DCEs.

Coleambally Irrigation Area (CIA) and surrounds in southern New South Wales. The Murrumbidgee Irrigation Area (MIA) is north of CIA and the Murray Irrigation Limited (MIL) is south. Heavy green lines represent the 1:250,000 scale map sheet boundaries and light blue lines represent the 1:100,000 scale map sheet boundaries.
The CIA is located in southern NSW (see inset). It falls completely within two Landsat ETM scenes, allowing for an 8-day repeat cycle.
