|5127 - Google Earth Plus||13/07/2005 - 10:00:31|
|I have been playing lately with the beta of Google Earth Plus, the next-generation reworking of Keyhole, the interactive 3-d "virtual flyover" aerial/satellite mapper that Google bought a while back. |
It integrates Google's new satellite/aerial database (the one they're using for Google Maps), but includes medium (not low!)-res satellite coverage of the whole earth - not just the US - and has detailed aerial coverage for many more foreign cities (including vector-map layers for some).
It allows users to create and share annotations that include icons, text labels, lines of adjustable width and color, and outlined and/or filled polygons of variable color/transparency that can be "extruded" upward in space to form column-like 3-D buildings.
Users can also overlay other maps and graphics onto the 3-D terrain, (including web-based sources that update like weather satellites and radar). Overlays have variable transparency, so you you can fade them in and out and see both the map and the aerial/satellite data at the same time. Overlays can also be shared with other users.
The vector-map layers, which can include street maps, political boundaries, zip codes, park boundaries, local and commuter rail transit, as well as many categories of labelled icons - both yellow-page-like business classes and civic elements like schools, fires stations, churches, and hospitals.
They've also added the Local Search and Driving Directions feaures from Google Maps (including a cool mode that "flies" along the marked route).
In addition, they've added a data layer that has pre-built 3-D extrusions of 39 high-rise urban cores in the US. You can virtually "fly through" the skyscraper canyons and create 3-D perspectives that include the built-up skyline (renedered as grey 3-D colums).
You can even render the 3-D buildings over the vector maps over your semitransparent overlay over the aerial/satellite photos.
It's pretty seriously cool. :-)
