Image Description:



The 1979 Lansat Multi-Spectral Scanner (MSS) image mosaic of East Timor is comprised 

of three individual MSS 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 1979_mosaic_large.jpg shows a dramatic improvement in data quality 

over the 1972 mosaic.  Note the seasonal differences between the western (9/05/78) and 

central (7/19/80) regions of the island, as well as the differences in terrain.  The 

eastern image is dated 10/13/79.  The false-color composite shown in this JPEG image was 

created using bands 4 (near infrared), 2 (red), and 1 (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 57m.  

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 MSS images and image mosaic are 

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





Landsat MSS Images in the 1979 mosaic:



  1)  MSS (WRS 1 Path 118 Row 66: 05 Sep 1978) Western region of East Timor.

  2)  MSS (WRS 1 Path 117 Row 66: 19 Jul 1980) Central region of East Timor

The accuracy of the georeferencing is documented below.  For each scene, the highest RMS 

value for a reference point is listed.
