I spent a little time today starting to convert some of my pages to the Google Maps API version 3. At the same time I thought I’d convert my geocoding to use the latest version since I was sure it would have improved since it was added to the API and failed to work too well three years ago. But no, it still sucks big time for postcode geocoding, as this test page demonstrates. But what is strange is that the GlocalSearch class still does a fine job of geocoding. Same company, different APIs and different results. This can’t be down to the Royal Mail throwing their toys out of the pram since the Ordnance Survey now provides geocoded postcode data for free so I assume it’s down to Google stuffing up.
