Image Description:

The 1972 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 1972_mosaic_large.jpg is comprised of some of the first Landsat 

MSS images.  As a result, the image quality is not very high, and data artifacts 

characteristic of these early data (striping, missing data values, etc.) can be 

seen in the images.  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.  Image dates (from left to right): 8/13/72, 

10/23/72, 10/17/1973.  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 1972 mosaic:

  1)  MSS (WRS 1 Path 118 Row 66: 13 Aug 1972) Western region of East Timor.

  2)  MSS (WRS 1 Path 117 Row 66: 23 Oct 1972) Central region of East Timor

  3)  MSS (WRS 1 Path 116 Row 66: 17 Oct 1973) Eastern 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.

MSS Scene			RMS

p118_r66			0.60

p117_r66			1.01

p116_r66			1.17
