The landsat-7 picture mosaic of Australia has 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.
