Yesterday Google updated their 3d buildings layer in google earth so that now downtown Helsinki is modelled. It all looks really good, but clearly some of the modelling was automated as there are plenty of building facades that are just the vegetation in front of the building. This should be cleared up in time though. Also I hope they can start to add more to Vantaa and Espoo and really make it a map of Greater Helsinki proper.
Also last week I started a flickr group Finnish Architecture and Google Map of the same name, the flickr group is totally public and just drop me an email to be able to edit the google map. Hopefully these two places can be for collaboration and discovery for everyone. Read on for the map.
