[postgis-users] Coordinates transform

Yes.  Use ST_Transform.


Basic approach is 
1) bring your data in with right SRID
2) Use AddGeometrycolumn to add a new column
http://postgis.refractions.net/documentation/manual-svn/AddGeometryColumn.html to add a new column with new srid you want to use

3) Update the new column with 
UPDATE new_column SET new_column = ST_Trasform(old_column, old_srid, new_srid);

4)Drop the old column with DropGeometryColumn

Hi All,

I have a list of longitude / latitude  records in TM65 projection  which
needs to be transformed into Google Map standard (UTM). Is Postgis  proper
tool for  that kind of transformations ? I mean .. can I import the data and
then use sql function to transform the data ? If yes could you point me
somewhere I could start ?


 Regards,

Luk
