Today we’re having a peek at the newly revealed and newly-public “most accurate” high resolution terrain map of Antarctica. This is REMA, or the Reference Elevation Model of Antarctica. Straight from the folks at Ohio State University, this map is made by what its creators say is “applying fully automated, stereo auto-correlation techniques to overlapping pairs of high-resolution optical satellite images.”
The creation of this map comes in a large part thanks to open source software called Surface Extraction from TIN-based Searchspace Minimization (SETSM). This software, developed by M.J. Noh and Ian Howat at Ohio State University, helped generate the most massively accurate map of Antarctica ever created. This map is presented at 2 to 8-meter spacial resolution.
“It is the highest-resolution terrain map by far of any continent,” said Ian Howat, professor of earth sciences and director of the Byrd Polar and Climate Research Center at The Ohio State University. “Up until now, we’ve had a better map of Mars than we’ve had of Antarctica. Now it is the best-mapped continent.”
We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter
