Google Earth has a new feature that allows users to observe the evolution of a site over time. The Search Engine API for now is only accessible to a limited group of partners.
Google Earth has a new feature that allows users to observe the evolution of a site over time, between 1999 and 2011. The
new application called Google API engine is the result of a joint
effort that brought together Google, Carnegie Mellon University Robotics
Institute and the U.S. Geological Survey (USGS).
The images displayed were taken by NASA satellite Landsat program over thirteen years. The large amount of data involved was the great challenge of this process. Google has created the largest library of images from Landsat archive over 1.5 million images. Every day thousands more are added.
Rebecca
Moore, manager of engineering for Google Earth Engine said that "the
sheer volume of visual data is difficult to exploit by conventional
means ... Together, we can offer an intuitive and easy method to explore the planet in space and time. "
The new Google Earth tool is based on technology GigaPan Time Machine, Carnegie Mellon University. It is possible to travel smoothly from one section to another video without the need for plug-ins like Adobe Flash. The image file is converted to video with zoom that can be easily accessed through a modern browser.
Randy Sargent, a scientist at the CREATE Lab's Robotics Institute in Pittsburgh, commented on the importance of the new tool, predicting that will help the public discussions on land use, climate change and environmental policies. "We continue to argue about why deforestation ... but we can not continue to discuss it really happens."
