After the first few sets of introductions, image collections from cities added were more detailed, often including every side street, especially in areas closer to the center of the city. More suburbs and other nearby cities were included.
The coverage of various cities has in many cases, subsequently been enlarged and improved, but not necessarily on the same date as new cities have been added. Improvements have included the additions of streets in neighborhoods where previously only main roads had been covered, expansions to more suburbs, and views to the sky where previously only views to a certain height were provided.
Initially when a group of cities were added, only those cities and their own suburbs would be a part of the image collection. However June 10, 2008 introductions also included cities in covered areas without camera icons and isolated from any other camera icons. Many more cities were added without icons on August 4, when the only U.S. city added with an icon was New Orleans.
On November 4, 2008, three more U.S. cities were added: Washington, D.C., Baltimore, and Seattle. More parts of Seattle are available in high quality view (like Mercer Island and center of the city).
