This Landsat image is a mosaic of two Landsat 5 TM images showing the extent of flooding in northern New South Wales during mid-December 2004.
The images were sourced from the ACRES Digital Catalogue which is freely accessible to the public through the ACRES web site. The main purpose of the catalogue is to enable viewing of a low resolution "quick look" images to help customers determine if they wish to purchase the full resolution product.
In these images water appears as shades of blue while moist bare soil appears as shades of red/pink. Healthy vegetation mostly appears as shades of green, with some Eucalypt forest in the south (Pilliga Scrub) tending to a brown colour. Some white scattered cloud and associated shadows appear in the south-west of the image.
The flood waters can mainly be seen west of Wee Waa, and north-west and south-west of Moree. Images such as these can be used by landholders, environmental professionals and emergency managers to map flood extents and to plan responses for future flood events.
The following two images show the flood area in greater detail. They show the standard size and resolution view of a 'quick-look' image available from the Digital Catalogue.

Most ACRES Landsat prices have been reduced by approximately 25% from 1 November 2004. A result of efficiency gains in our production processes, this reduction brings the average Landsat product price more in line with its current cost of transfer, as required by the Australian Government's Spatial Data Access and Pricing Policy. The lower prices means that an ortho-corrected full scene Landsat product now costs only $1200, compared to the previous price of $1600.
This significant price reduction makes Landsat imagery more affordable to a wider range of users for a variety of applications, further demonstrating the Australian Government's commitment to maximising accessibility of spatial data by the public.
The price reduction applies to all Landsat 5 TM data in addition to historical Landsat 7 ETM+ data acquired before May 2003 (ie all Landsat 7 SLC-On data). The recently introduced Landsat 7 SLC-On/ Off composite product prices remain unchanged while Landsat 7 SLC-Off have been adjusted slightly. Landsat MSS prices remain unchanged.
