[postgis-users] Transformation problem using transform()

[Marc Angelo]

Hi

Thanks very much Michael that worked but maybe someone can help me with
this. If I run those waypoints through a transform I get the following
geometry:-

SELECT Transform(position,27200) FROM waypoints =
0101000020406A0000B856779E53AB41417FC37EE399E55441


Ran the geometry through the AsEWKT function as follows:-

SELECT AsEWKT('0101000020406A0000B856779E53AB41417FC37EE399E55441');


...and I get the following answer.
"SRID=27200;POINT(2315943.23801693 5477991.55461204)"

I have now changed my import code to change the Lat Long of the co-ordinates
around which does give me the correct Lat Long using the AsEWKT function
using srid 4269 and 4326 but I get the above result using other srid's such
as 27200......

any help would be greatly appreciated

Cheers
Marc
