[postgis-users] I can't make sense of this.

[Emilie Laffray]

Why would you expect them to be similar? There are different sets of
coordinates.
Your first set of coordinates looks like wgs84 but you set the srid to
Google srid.
It doesn't make sense.

            )

AS gcs



3857 is “Google’s” SRID, and 4326 is a fairly standard GPS SRID. I’m getting
this:



Goog: "POINT(-81.064544 40.28787)";

Gcs: "POINT(-0.000728215188753794 0.000361912093851508)"



What am I doing wrong, that they’re so different?
