Multispectral Imagery Python - NAIP, Landsat, Fire & Remote Sensing


Welcome to Week 6!

Welcome to week 6 of Earth Analytics!

At the end of this week you will be able to:

  • Describe what a spectral band is in remote sensing data.
  • Create maps of spectral remote sensing data using different band combinations including CIR and RGB.
  • Calculate NDVI in Python using.
  • Get NAIP remote sensing data from Earth Explorer.
  • Use the Landsat file naming convention to determine correct band combinations for plotting and calculating NDVI.
  • Define additive color model.

Download Cold Springs Fire Data (~150 MB)

Or use earthpy et.data.get_data('cold-springs-fire')

The intermediate NDVI plots below are not required for your homework. They are here so you can compare intermediate outputs if you want to! You will need to create these datasets to process the final NDVI difference plot that is a homework item!

COMPARISON plots - intermediate NDVI NAIP outputs. These plots are just here if you want to compare your intermediate outputs with the instructors.
