• Using grid index systems in Mosaic
  • 1. Read the source point and polygon datasets.
  • 2. Compute the resolution of index required to optimize the join.
  • 3. Apply the index to the set of points in your left-hand dataframe.
  • 4. Compute the set of indices that fully covers each polygon in the right-hand dataframe
  • 5. ‘Explode’ the polygon index dataframe, such that each polygon index becomes a row in a new dataframe.
  • 6. Join the new left- and right-hand dataframes directly on the index.
