I have a table in postgres DB named "building_footprints".

Please see attached image

and running below query to table

SELECT row_to_json(fc) FROM (
SELECT 'FeatureCollection' As type, array_to_json(array_agg(f)) As features FROM (
    SELECT 'Feature' As type, ST_AsGeoJSON(lg.the_geom)::json As geometry,
    row_to_json((gid, the_geom)) As properties FROM building_footprints As lg
) As f) As fc

Query Result is:

I want to convert coordinates value(coordinates":[[[[530500.00039933,545400.008863266],) in to lat/long.
