I'm using GostGIS when I enter following you can see the input point is transformed:
=# SELECT ST_ASEWKT(ST_GeographyFromText('POINT(-33.7832527413259 151.120353207011)')); NOTICE: Coordinate values were coerced into range [-180 -90, 180 90] for GEOGRAPHY st_asewkt ---------------------------------------------------- SRID=4326;POINT(-33.7832527413259 28.879646792989)(1 row)Firstly I don't understand why the point is transformed (it's for a point in Sydney Australia so it's a real lat/lon) nor can I work out how to get the original lon value back (~123 is an odd size difference)
Any suggestions (probably a bit of a noob question as this is my first use of a GIS system)
