[mapserver-users] Projection question - Australia

[Marie Flanagan]

Hi all,

I have a question about projection.  My map data of the NSW area of Australia uses WGS84 datum and spheroid.  Units are in geographic Digital Degrees.  This looks fine when displayed in mapserver.

I also have a flat file of x,y co-ordinates from the AMG zone 55 which I want to overlay on the map.  I have managed to figure out how to generate a shape file for this.  But I am now left with the question of how to convert from AMG cartesian co-ords to WGS longitude and latitude.  I think it may be possible to convert these using PROJ4 before I create the shape file, but I am not sure if it's possible to convert from AMG to WGS.

I will continue to search for PROJ4 examples to see if this is possible but in the meantime if anyone could advise I would be most grateful.  I am not a cartographer so excuse any obvious ignorance in the wording of my question!

Regards,

Marie
