Take the 2-minute tour ×  I am a bit confused on EPSG:4326 and
EPSG:900913. I thought that they were both same. Though as I am
placing my features over GMaps, which is EPSG:4326, I need to
define the srsname of the WFS layer as EPSG:900913 to get it
into the right place. If I define srsname as 4326 it is
projected somewhere completely wrong.  Could someone explain it
a bit more in detail as to what is wrong here?  share|improve
this question Yes, it does. The two are exactly equivalent. –

EPSG:900913 uses an authalic sphere. –  arcsump Jan 24 '13 at
7:55 As a point of trivia: 900913 was originally rejected as a
credible projection by European Petroleum Survey Group (EPSG) so
Google (who invented it for the web) gave it their own number,
which if you type it on an old fashioned calculator spells
'googlE' (substitute '9' for 'g' and squint a bit). Eventually
EPSG relented and allowed 900913 into its geodetic repository
but gave it the number 3857. –  M
