News Roundup: Poles Overlays, Rocket Garden, Army Topos, Astronomy, Roads

  • Poles overlay in Google EarthPoles Overlays – Gerardo Paz has posted another good idea. He points out that you can use the new photo overlay feature of Google Earth 4.2 to place image overlays over the poles. Google Earth has a problem with normal photo overlays at the poles – due to the geometry of Google Earth and the poles reducing to a single point. In fact, the base imagery itself has difficulty with that region. But, Gerardo shows an example of a photo overlay working quite well over a pole. The scientists for International Polar Year should take note. Gerardo also provides translation services for the Spanish version of GEB.

  • Rocket Garden – The Google Lunar X PRIZE web site has a page that lets you load a collection of scale 3D models of rockets so you can compare them to your favorite landmarks. Visit the rocket garden page and enter an address to load the models in GE at that location. Turn on the 3D Buildings layer to compare to other 3D models. via OgleEarth.

  • Army Topos – PriceCollins at the Google Earth Community has been putting together a KML collection of hundreds of topographical maps which were created by the US Army Mapping Services and organized by the Perry-CastaƱeda Library of the University of Texas at Austin. Read Price’s post for more details, or download the collection to see what is available – mostly for areas in India and southeast Asia at the moment.

  • AstronomyGoogle Sky is more than just another Internet planetarium program. Because it is built on top of a very broadly installed application (Google Earth), and is built on standardized file formats (KML), it enables scientists to confidently develop ways to share their data and expect it to be available to a broad cross section of the world. Stefan Geens at OgleEarth talks about how observational astronomy will be transformed by these developments.

  • RoadsGoogle announced a few days ago that they have added 54 more countries with roads information for Google Maps. In a few weeks or months, these roads layers should make their way into the Google Earth server as well.
