comment SRID error in mapserver
Along with having the wrong projection in the database this did the trick nicely. Thanks! I really need to learn more about mapserver as it seems very powerful - unfortunately I'm quite new to GIS and projections though so it seems like quite a steep learning curve.

comment SRID error in mapserver
Excellent point.. I tried those queries and it reported that the SRID was -1. I used MerseyViking's technique to change the SRID and that fixed that issue. Thanks!

comment Most suitable open source GIS platform
Just had a look at UDig and although it looks pretty feature full and handles a lot of files it does seem to be quite slow at loading large datasets. Hopefully it'll improve in the future and I'll reconsider it. Thanks anyway!

QGIS does look very good, just loaded some huge layers and it crunched through them very quickly. Struggling to get the API up and running but I'll persevere!

comment MapServer - map rendered at the wrong angle
The conversion from OS to WGS84 was fine as I checked the coordinates after the conversion and they were spot on. It was the conversion to postgis' geometry format that did it as the coordinates were the wrong way round! Not sure what you mean about not using a projection though as I've specified 4326 throughout the map file - although the data looks correct I still have to skew it to make it line up with the google maps data..

comment MapServer - map rendered at the wrong angle
Cheers guys, turns out the conversion from lat/lon to postgis' geometry format was in the format lon/lat.. documentation surrounding that was pretty sketchy! Flipped the coordinates round and everything works as expected now. Same goes for the mapserver coordinates.. didn't realise it was lon/lat ;)

Interesting idea! I can't work out how to tell MapServer though, the data gets passed to MapServer in PostGIS geometry format.

Sorry, which X and Y coordinates? Are you recommending to change a setting within MapServer or at the database level?

It was originally in the Ordnance Survey format - I used a converter to convert it to WSG84
