| Abstract |
NASA has made available seven-band, 512x512, thirty-meter resolution data sets from the Landsat Thematic Mapper and a step-by-step procedure for viewing and analyzing them using a freeware application that is available for both Macintosh and PC computers.
Download the images and the software and you can be doing remote sensing today! For each location we provide the following:
<li>A Mac self-extracting archive containing the seven individual band files and headers.
<li>A PC self-extracting archive containing the seven individual band files and headers.
<li>A Mac self-extracting archive containing a single file composite of the seven bands and headers (.LAN format).
<li>A PC self-extracting archive containing a single file composite of the seven bands and headers (.LAN format).
<li>A three-band composite in GIF format, bands 3,2,1.
<li>A three-band composite in GIF format, bands 4,3,2.
<li>A three-band composite in GIF format, bands 7,4,3.
Perhaps the simplest multispectral image processing task is the creation of a three-band composite. A three-band composite is created by using the measured reflected energy in each of three TM spectral bands to control the amount of blue, green, and red in a color output image. The step-by-step tutorials will show you how to create a three-band combination from TM data sets using the MultiSpec software. |
