I certainly sympathize :) I _think_ a similar thing happenned in New Orleans, where higher resolution older images pushed out lower resolution newer images, and this caused a huge uproar. The images around Nanaimo are only as good as they are because we were able to build support at the City to provide them to Google. Perhaps given enough public pressure, other municipalities would do the same. One thing that we ran into back in 2005 was that our initial contract did not allow us to do this, so when we re-flew in 2006 we made sure that we retained the rights to provide the imagery to external agencies for the public good.

Was it the change to IMTCAN data just recently that pushed the Metro Vancouver imagery back to images over 3 years old? We just had an update that brought us up to current data, images which were perhaps 6 months old - I think less than a month ago - and yesterday I looked and we are now back at images from over 5 years ago. Buildings that were taken down and now replaced are back again. There was a data set in between that was perhaps 3 years old or a bit older which was slightly lower res than the 5-year-old data. But having the current stuff and then losing it is like being a kid who has their christmas toys taken away on December 26th. I am a member of the Port Moody Heritage Society and on the Port Moody Heritage Commission and so being able to see current information actually is useful to me, though doing this as a volunteer on my own time and money I have no budget. It is useful to be able to locate the heritage homes and sites in the city and make sense of where the new rapid transit planned routes will go to see how they impact things. That plus get a sense of new civic planning. But darned but the imagery around Nanaimo is incredible! I also love exploring and hope to do some on the Island in near future, at least vicariously. http://gnomestead.com/ http://portmoodystationmuseum.blogspot.com/ The increase in resolution looks great.
