 This also works for distance join. You first need to use `ST_Buffer(geometry, distance)` to wrap one of your original geometry column. If your original geometry column contains points, this `ST_Buffer` will make them become circles with a radius of `distance`.
 
-Since the coordinates are in the longitude and latitude system, so the unit of `distance` should be degree instead of meter or mile.

 In a nutshell, run this query first on the left table before Step 1. Please replace `METER_DISTANCE` with a meter distance. In Step 1, generate S2 IDs based on the `buffered_geom` column. Then run Step 2, 3, 4 on the original `geom` column.
