The tools provided through google have evolved once again. Recently google launched a new beta version of the google earth application. It is now possible to explore oceans on google earth. This feature allows users to explore the oceans, examine melting ice caps, and use a feature called shipwrecks. The shipwreck feature allows users to explore more than forty shipwrecks, through educational videos. The shipwreck section contains some historical information, and may be a neat way to introduce the more historical side of mapping to the public.
Similarly, google earth now includes a historical imagery feature. This feature lets users explore a variety of satellite images from various periods, which highlight how certain areas have changed over time. The user can also select the time span they want to examine for a particular location. Currently this feature is only available for select locations, but despite this limitation, google earth is moving towards providing more historical context, which is never a bad thing for the history buffs.
