Socrata was acquired by Tyler Technologies in 2018 and is now the Data and Insights division of Tyler. The platform is still powered by the same software formerly known as Socrata but you will see references to Data & Insights going forward.

# set_projection

##### Function: set_projection
  function to explicitly set the projection value on geometries which do not have projection
information. If the geometry came from a non-shapefile format, it will not have projection
information, and will default to WGS84. If you know that the projection is something
other than WGS84, you may set the projection using this function, which will allow you
to reproject using the reproject or reproject_to_wgs84 functions.

Therefore, this only has an effect when used with the reproject transformation fucntions,
as it simply sets the source projection on the datum.

Examples:

reproject_to_wgs84(set_projection(to_point('POINT(30 10)'), '+init=epsg:3627'))
-- Result: {"type":"Point","coordinates":[-77.51923750265013,40.11248612944048]}
