Image Description:



The 1999-2000 Lansat Enhanced Thematic Mapper (ETM+) image mosaic of East Timor 

is comprised of three individual ETM+ images.    The original images were purchased 

from the Tropical Rain Forest Information Center at Michigan State University 

(http://www.bsrsi.msu.edu/trfic/index.html), and georeferenced to two geocorrected 

Landsat Image mosaics provided by NASA (http://zulu.ssc.nasa.gov/mrsid/mrsid.pl) 

covering the East Timor region.



The mosaic image 1999_2000_mosaic_large.jpg shows many interesting new infrastructural 

developments in East Timor during the 1990’s.  At the eastern end of the island, a 

large reservoir has been created.  The city of Dili, located on the north shore near 

the middle of the island, was the site of a serious of riots during 1999.  In this image, 

one can see fires in Dili, with grey smoke plumes trailing trailing off to the south-west 

(see Dili Fires image, this page).  The false-color composite shown in this JPEG image 

was created using bands 4 (near infrared), 3 (red), and 2 (green) for red, green, and blue 

components of the image, respectively.  Vegetation appears red in this image, while rivers 

appear blue-green, and clouds white.  The raster-cell resolution of the original images is 

28.5 m.  The raster-resolution in the JPEG file has been resampled to 250m to provide highly 

accurate image in a portable size (less than 1 MB).  The original ETM+ images and image mosaic 

are archived at the Yale University Center for Earth Observation (www.yale.edu/ceo).
