Google Earth 5 beta release includes oceans, history and Mars

Two days ago Google has released beta version of it's very popular application Google Earth. This version is a beta so we should expect some minor changes in final release.

Right after start you can notice some changes. New features are briefly described in start up tips.
Key new features are:
  • Oceans
  • Historic images
  • Mars
  • Tours
Here are startup tips about new features.



This is a nice feature and one that was expected to be part of Google Earth sooner or later. After all water covers about 71% of Earth's surface. Mapping of seabed is valuable teaching tool and it provides an insight into greater picture of our planet.
Rendering of water surface is quite nice and animated. Screenshot below can't really show nice surface and moving water but you get the idea.
History view is a nice feature where availble. For example Manhattan has earlest imagery from 1974 right up to 2009. See examples below and have a lool at the top of the map area for time slider.
Some other places (like my home town of Osijek, Croatia) has imagery from 2006 onwards only. Hopefuly this will improve over time like other Google Earth coverage.
 Tours can be created with full control over speed, wait at features, camera tilt and other settings. Given enough time we should see plenty of tours.
 These features are also described in help (accessible on-line) over here. Google Earth can be downloaded from Google Earth main page.


Coverage and review of Google Mars is coming soon.

ArcGIS Server API - Microsoft Silverlight

ESRI has revealed yet another API for ArcGIS Server. In addition to existing APIs for .Net, Java, JavaScript and Flex now you can use Silverlight. This is just announced and more will be shown at ESRI Developer Summit. There will be a technical seesion about it.
On Developers Blog you can see the video (embeded below) and links to other two articles about ArcGIS Server and Silverlight. This in intersting since Microsoft is planning release of Silverlight 3 and even 4. New features for version 3 (due out this or early next year) will include major media enhancements (including H.264 video support), major graphics improvements (including 3D support and GPU hardware acceleration), as well as major application development improvements (including richer data-binding support and additional controls).
It's good to see ESRI expanding the list of supported APIs. It definetly broadens applications and number of developers.
