Explore Google Earth on Earth Day

April 22nd is Earth Day, which we traditionally celebrate by looking back at some of the environment related stories of the past year.

NASA and Japan make ASTER imagery available for freeJapan and NASA made the imagery from ASTER available to the public for free. Thank you to GEB reader ‘sanchezpaus’ for letting us know that the ASTER imagery is better resolution than satellite imagery at 15 m per pixel for ASTER imagery vs. 30 m per pixel for Landsat. This means the vast imagery database will be of significant interest to people doing environmental research that requires satellite imagery.

The Oklahoma EarthquakesWe had a look at the increased frequency of earthquakes in Oklahoma. Google Earth combined with data from the U.S. Geological Survey (USGS) makes an excellent tool for studying the geographic distribution of earthquakes with time.
 
 

Watching Antarctic Ice Sheets Crack with Landsat ImageryWe heard about an ice sheet in Antarctica slowly cracking and used Landsat imagery to watch it crack in Google Earth.
 
 
 
 

Fairy circlesWe had a look at a phenomenon known as ‘fairy circles’ and earlier in the year had a look at the patterns made by ant and termite nests.
 
 
 
 

Google’s Skybox Imaging renamed Terra BellaGoogle’s Skybox Imaging was renamed Terra Bella to indicate a change of focus from just a satellite imaging company to pioneering the search for patterns of change in the physical world. We expect to see a number of environment related projects come out of Terra Bella in the future.
 

New Sea Floor Map for Google EarthGoogle updated the Google Earth sea floor map with higher resolution data from a variety of sources, including the Scripps Institution of Oceanography, University of California, San Diego and the Lamont-Doherty Earth Observatory.
 
 

OpenForis a Google Earth based applicationWe had a look at a tool called Open Foris that works with Google Earth to make mapping land use and land use change easier.
 
 
 
 

Wild Dogs and the Google Earth APIWe had a look at a tool that is very similar to Open Foris, but uses the Google Earth API. It was used to map land use in East Africa to aid in the study of African Wild Dogs.
 
 
 

NASA Near Earth Observations in Google EarthNASA Near Earth Observations (NEO) data is a large collection of multi-year global datasets. We had a look at how to import them into Google Earth and make animations from them.
 
 
 

Tracking wild fires in Google EarthWe had a look at various resources for tracking wild fires in Google Earth and also had a look at the scars left behind by some large wild fires in California using Landsat imagery.
 
 
 

Celebrate World Oceans Day with the Catlin Seaview SurveyThe Catlin Sea View Survey is a project to document the worlds reefs in 360 degree panoramic photography. The results can be seen in Street View. We had a look at it on World Oceans Day last year.
 
 
 

Average Cloud Cover Map and Map ProjectionsWe had a look at some average cloud cover maps from NASA.
 
 
 
 
 

Technology and sustainabilityRebecca Moore, Engineering Director for Google Earth and Earth Engine & Outreach wrote an interesting article about three projects (Global Forest Watch, Project Sunroof and Methane Maps) that Google is doing in collaboration with others using technology to achieve sustainability goals. We discussed the possible reasons why Google Earth was not used in these cases.

About Timothy Whitehead

Timothy has been using Google Earth since 2004 when it was still called Keyhole before it was renamed Google Earth in 2005 and has been a huge fan ever since. He is a programmer working for Red Wing Aerobatx and lives in Cape Town, South Africa.
