Sprint 2 - Determine appropriate metric(s) to measure vegetation coverage

[baogianghoangvu]

We need to determine the appropriate metric(s) to measure vegetation coverage.

So far @ntmt2903 has recommended the following options:

• NDVI and EVI are tentatively the metrics of choice.
• Otherwise, "green" color spectrum can be used instead.

Please:

• continue investigating these metrics or others you may find, keep a list of appropriate metrics so we have more options to fall back on, depending on how @thunguyenuehk39 proceeds with investigating data sources,
• then implement a Python solution to compute these metrics. As a first step, you may want to create a function like so:

  def score_per_pixel(pixel):
      score = 0  # todo
      return score

• Document your research:
  • brief descriptions of metrics
  • references
• ideally, the solution should be vectorized for efficiency, but feel free to design your own solution.

Please create a new branch named metric to differentiate from the existing _dev branches.
