known_region

Provided value to use to determine the proper spatial reference system to use in geometric analysis. Providing an SRID value such as 5070 or a US state code such as MN will skip the sometimes expensive determination of the correct SRID for the feature. However, if the feature does not actually apply to the provide known_region hint, then indexing may fail or return incorrect results. If in doubt, leave this parameter blank.
