I currently have the GeoJSON files containing the census/administrative polygons and metrics associated with them. However, I want to add the ability to view that same data with custom polygons. For example:

  • I want to drop a marker and view the metrics in a 5km radius
  • I want to draw a rectangle and view the metrics only in that area

Could you please recommend the best way to approach this problem - right now I am thinking along the lines of finding the % intersection of the custom polygon with the underlying administrative polygon to get the proportionate metrics. Is this even feasible?
