Calculate the population of an area affected by active wildfires

Create estimate of population affected by active fires

The goal is to estimate the amount of people affected by active fires in a given area, using VIIRS satellite data and US Census data

  1. Cluster fire data points from VIIRS data into groups, representing active fire areas
  2. For each group, create a polygon that contains all points (a convex hull), this represents the boundaries of a given fire area
  3. For each polygon, create an intersection against Census tract boundaries.
  4. Calculate the populations of the tracts that are fully contained
    • ?
  5. Calculate the populations of tracts that are partially contained, based on the percentage of overlap
    • ?
  6. Profit?
