Google Earth 5

Again slightly off-topic, but I could justify its relevance if challenged. The latest release of Google Earth is now available and has two or more things of great interest.

Aside from those of you interested in looking at Mars imagery, we now have both historical imagery and the long awaited for Google Ocean.

Firstly, historical imagery. In essence every single historical imagery update since the start of Keyhole Earth/Google Earth is now available, and also satellite and aerial imagery going all the way back to 1940. This makes for some interesting viewing over the Antarctic. Some of the changes in Peninsula ice shelves extent are well done, others need a bit of work.

The good news is Google have been proactive in asking for any other historical imagery and air photography that we have available to add to this collection. So there may be some gaps currently, but hopefully this will improve.

Secondly is the eagerly anticipated Google Ocean. The updated bathymetry is visible below, but now you are able to dive below the surface although I admit the navigation takes a bit of getting used to to and is easier with a 3d mouse. A bit of time is needed to see what else is included in Google Ocean and how much use it might be to visualise various data. Ideally we can automate the addition of 3d objects, profiles etc. We’ll let you know.

As ever, Stefan Geens at Ogleearth has more informed comment here and here. The second article highlights some Antarctic material provided by NSF and Census of Marine Life.
