Landsat 7 ETM+ mosaics are available in standard tiles with the resolution of 14.25 metres. These tiles are delivered in a Universal Transverse Mercator (UTM) / World Geodetic System 1984 (WGS84) projection in ECW file format with stand alone viewing software. The mosaics generally extend north-south over 5 degrees of latitude, and span east-west for the full width of the UTM zone. For mosaics between 60 degrees north and 60 degrees south latitude, the width of the mosaic is the standard UTM zone width of 6 degrees of longitude. For mosaics above 60 degrees of latitude, the UTM zone is widened to 12 degrees, centered on the standard UTM meridian. To insure overlap between adjacent UTM zones, each mosaic extends for at least 50 kilometers to the east and west, and 1 kilometer to the north and south.

These mosaics are the most accurate, commercially available base maps of the world created, from Landsat imagery. The tiles and mosaics have a better positional accuracy (50 m RMS) than the vast majority of the world's 1:100,000 maps.

Worldwide Bundle of over 870 of these Landsat 7 ETM+ Mosaic Tiles is now available on DVD-R for $6,000.00 USD (in either JPEG2000, MrSid or ECW file Format, pricing exclusive of applicable taxes & shipping costs).

Landsat 7 ETM+ Mosaic of the Globe

The most complete and detailed mosaic of the globe is now available as a single ECW file on DVD. Over 130GB of Landsat 7 ETM+ data has been seamlessly mosaiced and compressed to a 4.3 GB ECW file. Because of the incredible read speed of ECW files this mosaic can be accessed directly off of the DVD into your projects without requiring you to copy the file to your local drive.

Free Online GIS-Ready Satellite Imagery - tsunami images

They have been rescaled in most cases to show an area of interest, and thus do not represent the full resolution of the original QuickBird image. Parts of the sea floor rose by about 10 metres, displacing hundreds of cubic kilometres of seawater. That generated a tsunami - a series of huge waves that quickly fanned out across the Indian Ocean.
