I´m developing a GIS for a company and the coordinates are in UTM ED50(old standard in Europe) and and I need to turn to those used in Google maps ....... (WGS-84)
I've tried using the function:
ST_Transform (SRS_to.srtext, SRS_from.srtext)
SRS_to.srtext = WGS-84
SRS_from.srtext =UTM coordinates
but can not get the right result.....
Is it possible?
Thanks in avanced,
The st_transform format is as follow,
SELECT a.*, geom_col.ST_TRANSFORM(x.srtext, y.srtext) AS new_geom_col
FROM table a,
WHERE x.auth_srid = 9823 -- to coordinate system
AND y.auth_srid = 4269 -- from coordinate system
