Hmm, but EPSG:3785 is deprecated, or as EPSG says, "NOT VALID". EPSG:3857 is equivalent to EPSG:3785, it's just a different formulation. Here's the change request from EPSG's site (notice the Actions Take section):
Code: EPSG::2008.114 Reporter: OGP Request: Revisit spherical mercator used for some web mapping applications Actions Taken: Deprecated ellipsoid 7059, datum 6055, method 9841, projection 19847, CRSs 4055 and 3785, tfm 15973. Added methods 1024 and 1026, proj 3856 and projCRS 3857. Entity Types Affected: Ellipsoid; Datum; Coordinate Operation Method; Coordinate Operation; Coordinate Reference System Codes Affected: 7059; 6055; 9841; 15973 19847; 4055 3785 Report Date (UTC): 2008-12-11 Closed Date (UTC): 2009-02-10 -Josh On Fri, Feb 25, 2011 at 12:05 PM, M∡rtin Koppenhoefer <dieterdre...@gmail.com> wrote: >> M?rtin Koppenhoefer wrote: >>> >>> JOSM currently does not permit to set the Google / Bing / standard >>> Mapnik projection if I interpret this right (there is "Mercator" which >>> is EPSG 3857 according to JOSM).
