Imagery Today – Making Advanced Satellite Images Available
In this talk from O’Reilly Media’s Where 2.0 2010 conference, Walter Scott of DigitalGlobe discusses imagery techniques available today using images from satellites and airplanes. He discusses accuracy and the related manipulation of data sets. Data and imagery previously only available to governments is now becoming more widely available. Now depth maps of the ocean can also be made. Graphic processing units from the gaming industry can be leveraged to provide advanced geospatial-type imagery. Before and after images can now also be more effectively used to accurately track changes in what is happening on the ground. Data available from DigitalGlobal’s library can be used with various geospatial tools. For example, following the earthquake devastation in Haiti, DigitalGlobal made its images before and after the earthquake for Haiti available to first responders in the crisis.
If you, like me, are interested in graphics or Google Earth, do watch this 14 minute talk.
I need to mine the rest of the content from this conference to learn more about the latest in geolocation developments.
Interesting that you post this. We just released an announcement for our upcoming book on GIS – and my focus is on disasters.
Not a lot of legal issues involved in my chapter, but there are some privacy concerned raised.
I do have some notes on international law on remote sensing technology, but I’m tied down for exams right now.
Well, that’s a coincidence. Congratulations, Omar!
In the video he makes the comment that they are only allowed to be so granular with their images from satellites according to U.S. law, but they can “show nose hairs” with images taken from airplanes. Would love a future blog post when you have time.
Cheers,
