Google Earth Google Earth allows the user to combine geospatial data, with a 3-d view of the world, and the overlay of GIS and other data including real time transportation data.

Google’s new earth product Google is now offering a new product that will allow the user to display satellite and government and private GIS data source. The basic system is free but to create a useful application requires a license fee of several hundred dollars per seat. Their enterprise server for private application development is in the hundred thousand dollar range not including data.

Getting started: Downloading Click here to get the download and a video to assist you in getting started: O_2tova6ocCFQtwVAod-3nL1A O_2tova6ocCFQtwVAod-3nL1A Select Google Earth and any other tools from the Google Pack. YOU DON’T NEED TO DOWNLOAD ANYTHING ELSE.

GE First Step -- Finding your Home The first thing almost anyone does with GE is to see where they live, this includes even President Bush (MSNBC Oct 24, 06 interview) Click the Google Earth icon and then fill in the text Fly To box. You can use lat, Long or your street address.

GE Controls The controls are fairly simple to use. If you have a three button mouse, the thumb wheel moves you in closer or further away (higher altitude). The compass indicated the direction that you are looking. The inner arrows will move you in that direction indicated. Note the vertical slider takes you higher or lower in altitude. The horizontal slider tilts the image and allows you to look at 3 D objects.

GE -- Taking a tour Places is where you can save places of interest. Want to take a tour Click Sightseeing in Places and Then click [Tools]/Play Tour GE should start flying from one place to another listed under Sightseeing. Note to get the 3D view -- Check 3d Buildings in the Layers Window Downtown Chicago looking toward the Chicago River, with 3D Buildings

Google’s new earth product Here we see one of the more interesting 3-D applications showing a basic 3-D architecture of 33 US and major international cities (Sanborn Corp data). GE has a global digital elevation model (DEM) that allows the viewer to explore the terrain in 3-D. The application features an easy to use dashboard of controls and easy to use GIS databases including the 3-d buildings.

Finding information and data for GE The site cks.com/ offers files of various applications, tours, blogs to answer questions and videos for training. cks.com/ You need to register to get to be able to download files, etc. Example add weather to GE

Google’s new earth site Google’s new earth product allows users to add satellite and other imagery on a real time basis. Here we see NASA infrared satellite data superimposed on the earth.google.com globe tracking the same hurricane (Emily on July 19, 2005) Image is updated every 3 hours.

Adding Weather to Google Earth After registering for Google Earth Hacks click: Go down to either: –Weather forecast –Weather: Real time conditions Conditions.htm Conditions.htm Select USA Lightning USA.htm USA.htm Click Download File (near bottom of page) Select open with Google Earth Application Make sure the layer is checked (selected)

Using Google to find real estate Type “real estate” or “home for sale” in the search. Google will present form Add zip code or city,state in area of interest. Google will provide a dialog box to allow your to select home features and will give you google map etc.

Google Earth’s tracking Google Earth allows viewers to add data to its 3-d world including air traffic, marine, and land based vehicles.

Google Earth as a geographic information rich infrastructure Google makes easy to display GIS and other data that allows the creation of situational displays. Users can add custom static data, web cam locations, weather, and dynamic data with Earth’s supplied tools and KML scripts (XML). The 3-D buildings and terrain provide a tactical and strategic planning and operational tool.

Fboweb.com Fboweb has integrated real aircraft tracking data into the Google Earth (GE) and has created high useful displays of air traffic. This first application will surely lead to a next generation of multi modal supply chain tools. In order to use Floweb data with GE it is necessary to download KML scripts for each regional airport (click ) Fboweb supplies for a fee other useful applications for the pilot and aviation industry.

Google Earth with live 3-d air traffic

In the Google Earth merging Traffic Management Data The current model allows for aircraft arrivals for five pacing airports in the US (Boston, New York, Chicago, Atlanta, Los Angles, Miami, Seattle). Click on the gray airplanes to get flight id and other data. The white poles (allow estimate height), purple lines are the aircraft’s recent track in 3-d space.
