Explanation of Stretch Lesson 04

mjones01 commented 9 years ago

Currently this is introduced in Lesson 04 (https://github.com/data-lessons/NEON-R-Spatial-Raster/blob/gh-pages/04-Multi-Band-Raster.Rmd) lines 299-326 but is poorly address and potentially unnecessary.

1) Does it need to be explained? or can we remove it from the code? 2) How best to teach / explain the concept? 3) Is a graphic needed? eg. http://www.nrcan.gc.ca/earth-sciences/geomatics/satellite-imagery-air-photos/satellite-imagery-products/educational-resources/9389

4) Does it fit better elsewhere in the series?

@mjones01 will you please revisit this as well. We did create a stretch graphic but I'm also happy to look at this.

A graphic has been added and the explanation looks sufficient. Closing the issue.
