Landsat 7 Picture Mosaic of Australia
The Landsat 7 Picture Mosaic of Australia was produced by the Australian Greenhouse Office (AGO) as part of their National Carbon Accounting System. The mosaic is comprised of 369 individual Landsat satellite scenes acquired between July 1999 and September 2000.
Viewing the mosaic
Click on the image at left to view the picture mosaic down to a detail of 300 metre resolution. This broad resolution, combined with image compression, produces a file size suitable for online delivery. Note that our full resolution standard Landsat products are 100 times more detailed, using a 30 metre pixel, and contain a wealth of additional radiometric information from the 8 spectral bands on the Landsat ETM+ sensor.
• Click on the image to open a new window where you can zoom and pan around the mosaic.
• To view the mosaic you will be prompted to download the ECW plugin.
Accessing the mosaic data
The source data used to produce the Landsat 7 Picture Mosaic is available in a range of formats to suit both the novice and professional user:
Picture Mosaic file for download
The picture mosaic file may be downloaded at no cost from our web site in ECW (compressed) form. Customers must first register and agree to the Landsat 7 licence conditions to obtain an access key for download. To view the image you will need to install ERViewer which is available online for free. After download, the file can be viewed as a simple picture showing latitude and longitude at any point, or saved in a range of formats including GeoTIFF for use in GIS systems.
Go to the ER Mapper website to download ER Viewer by selecting their "downloads" page. Register and download the compressed picture mosaic file (58Mb - No Charge).

Picture mosaic data at lower resolutions
If you have no need for the detail and georeferencing information in the file above and/or find the above file too large, the following lower resolutions files are available for download. You must register and agree to the Landsat licence conditions to receive your access key for downloading the first two files below (1.2km pixel and 3km pixel). The third file (6km pixel) is available without registering.
Note that any reproduction of these mosaics need to be accompanied by the following minimum acknowledgement:

(You may wish to provide additional information in your acknowledgement such as the satellite type and dates of acquisition.)
The following very low resolution image is available without registering with us. Simply click on the link to view, then right click the image and select "save as".
Picture Mosaic as a poster
If you would like a hard copy of the mosaic, we can provide a glossy poster nearly 1 metre square (at 1:5 Million scale) for only $16.40. Posters may be purchased from our map retailers and remote sensing distributors around Australia.
Full spectral and spatial resolution data
Data from the Australia mosaic is available as the Landsat AGO Product Suite.
