In this application you can browse dynamically Landsat 7 scenes data and choose the combination of bands that the GIServer from inovaGIS will use for the false color composition. The Landsat bands available are the ones from visible spectrum (Bands 1,2 and 3) and from the near and mid InfraRed (Bands 4,5 and 7). Using the different bands for the false color composition it is possible to enhace the different environmental components of the landscape at different scales.

Mediterranean Basin
For the moment there four images available for the Mediterranean basin.
The first two are from the center east of Greece and the central part of Greece taken both on the 6th of August of 1999.
The other two images are from the Middle East region. Where the first is more or less centered in Jerusalem and where is also possible to observe the Dead Sea, Tel Aviv, Amman, Gaza Strip, and most of occupied Palestine. The second image covers the disputed area of the Golan Heights, and includes the cities Damascus, Haifa, Nazareth, the south of Lebanon and the Lake Tiberian. Both images were taken on the 7th August 1999.

SouthEast Asia
For the south-east Asia region there is a new Landsat scene of Singapore, where you can see some areas of Indonesia and Malaysia. The image is covered by clouds but you can detect the urban areas and the big harbor. You'll get better results with a 457 (or 451) false color composition.

These images were purchased by SGI (Silicon Graphics, Inc.) and since
these are free of any copyright restrictions, SGI makes the entire
contents of the CD's that they received available for download. I just downloaded the entire
scenes and put the inovaGIS server working with them.
The original files were in GeoTiff format and you can download them at the SGI site (opens a new window).
