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.
