Demonstration of vegetation score extraction

vegetation_grab.py

# Sample code to demonstrate the vegetation extraction from satellite imagery.
# The example region is a small plot in the central valley:

# https://gist.github.com/danhammer/47590518ece27c2ef0ab

# Specifically, this reports the mean and standard deviation EVI score for all 
# 30m pixels within the supplied polygon. To install the requests package on a
# Mac, type `sudo pip install requests` or visit this page for more comprehensive
