Re: [backstage] Converting between easting/northing and long/lat

[Barry Hunter]

I have recently got some code working for geograph.co.uk project.   It's not polished yet, but does work: http://cvs.sourceforge.net/viewcvs.py/geograph/geograph/libs/geograph/conversionslatlong.class.php?rev=1.1&sortby=date&view=log   (you will just need to change the class definition to remove the 'extends Conversions' which it doesn't need to function)   then can just be used:       $conv = new ConversionsLatLong();     list($e,$n) = $conv->wgs84_to_osgb36($lat,$long);     list($lat,$long) = $conv->osgb36_to_wgs84($e,$n);   there is a utility function to convert easting/northing to grid reference but not the other way yet! (osgb36_to_gridref)   Barry ----- Original Message ----- From: Paul Maunders To: backstage@lists.bbc.co.uk Sent: Tuesday, June 14, 2005 8:05 PM Subject: [backstage] Converting between easting/northing and long/lat Hi Guys,   On the subject of maps, I was wondering if anyone has any php code to convert between OS grid references or GB OS easting / northings and longitude and lattitudes?   Regards,   Paul Maunders
