Peering down from space - IMAGINE What will I see next? ERDAS

It was green, no it was red, no I thought we could only see the blue.  Well, it's all of the above.  The launch of the LandSat series of satellites has brought to us "regular" people and enormous amount of information.   Seeing the earth not only from a spaceship as a little blue ball but from the trained lenses of the EMR perspective, a picture will no longer be just a thousand words but a thousand multispectral pixels.

We used a view of the entire conternounmas (?) United States. Zoomed in to Washington State then zoomed in yet again to a smaller area, subsetting and clipping to obtain the area on the map below.   This pick is compliments of an October 3, 2011, pass of a thematic mapper.  The base spectrum band combinations were changed and whow! it's better than magic crayons.  The preparation for the final product is not a 1,2,3, deal, it takes time and many more layered steps to obtain an understandable product.
