To date, here are the known Google Maps mashups previous to today:
- Australia Google Maps Mashup Roundup (all known Aus mashups)
- New Zealand Explorer (Land Information New Zealand + Google Maps)
These mashups were based only on the satellite imagery which was first available for both countries, so it should be very interesting to see the new Google Maps API integrations that will emerge with street maps. Please drop me a line if you have any new mashups to share so I can post about them!
