[postgis-users] Replacement for Oracle's TRANSFORM_LAYER procedure?

[Bryan Hall]

Classification: DCL-Internal


I’m starting to look at the stored procedures we will need to move to PostGIS from Oracle, and I don’t see anything like SDO_CS.TRANSFORM_LAYER in the manual for a built-in procedure. Yes of course there is ST_Transform, but that does it in place, or in-line. However, here we are making a new table in a different SRID and it would be rather nice not to hard-code the columns in the source table (or MV in this case), or copy the table as a whole and then do a clunky in-place update. Yes, I’d rather just add another geography column and make it a computed column – but stupid ESRI software has to read this data. 😊

Is there a good site to look for “convenience functions” like this for PostGIS? I’d rather not spend time “re-inventing the wheel” if I don’t have to.

Thanks, Bryan
