Hello I'm trying to transform point coordinates from geographic latlon ED50 (EPSG:4230) to WGS84 (EPSG:4326) in Postgis, but the result is incorrect (input and ouput coordinates are the same, although they must be diferent):
select ST_AsText(ST_Transform(ST_SetSRID(ST_MakePoint(10,20), 4230), 4326)); st_astext -------------- POINT(10 20) The same problem with cs2cs from proj4 in a shell echo 10 20 | cs2cs +init=epsg:4230 +to +init=epsg:4326 10 20 After sources download and compilation, cs2cs gives good results: echo 10 20 | cs2cs +init=epsg:4230 +to +init=epsg:4326 9d59'57.2"E 19d59'55.54"N 102.459 But postgis is still returning the same point. I have checked /usr/share/proj and epsg file includes both 4230 and 4326 ok # ED50 <4230> +proj=longlat +ellps=intl +no_defs <> # WGS 84 <4326> +proj=longlat +ellps=WGS84 +datum=WGS84 +no_defs <> The same problem occurs in three pcs with Ubuntu 10.10 and ubuntugis-unstable PPA. I would apreciate very much any hint to solve this problem.
