The maps and videos on GreatAmericanEclipse.com are built from the work of Michael Zeiler, Xavier Jubier, and Fred Espenak.
Michael Zeiler produces the maps and animated maps on this website. He is a geographer employed by the leading provider of geographic information systems (GIS) software, esri.com. Michael has witnessed total solar eclipses since 1991. In 2009 while writing his book, Modeling Our World, he realized how advanced GIS technology could be applied to publish new eclipse maps of high precision and good cartographic quality. After creating his first eclipse maps for the total solar eclipse of July 22, 2009, Michael launched eclipse-maps.com in 2010 to showcase new and historic eclipse maps. Recognizing the widespread public interest of the August 21, 2017 total solar eclipse, Michael launched GreatAmericanEclipse.com on August 21, 2014. Michael is a member of the International Astronomical Union Working Group on Solar Eclipses.
Polly White is co-publisher of GreatAmericanEclipse.com and business manager of Great American Eclipse LLC. Polly is a seasoned eclipse chaser and loves to share her passion about the exquisite beauty of total solar eclipses. Polly directs the development of opportunities, partnerships, and public relations for Great American Eclipse LLC. Polly also manages product development and order fulfillment of our store at www.greatamericaneclipse.com/store. Polly and her husband Michael Zeiler look forward to many future eclipse expeditions to remote and special places on Earth.
Xavier Jubier has pioneered the development of high-precision eclipse calculations on interactive web maps. His website provides interactive Google eclipse maps for a span of five-thousand years including the solar eclipse of 2017. Xavier has travelled around the world to view solar eclipses including extreme eclipse expeditions to Antarctica. Xavier adapted his Solar Eclipse Maestro software to compute data used to produce the high-precision mapping of eclipse circumstances in the maps and videos on this website. These calculations are corrected for the precise shape of the Moon's limb as lunar mountains and valleys affect the onset and egress of totality by up to several seconds. Xavier is a member of the International Astronomical Union Working Group on Solar Eclipses.
Fred Espenak is widely recognized as the world's leading expert on eclipse predictions. For decades, he published eclipse predictions for NASA and recently retired from the NASA Goddard Space Flight Center. Fred has published the Thousand Year Canon of Solar Eclipses, 1501-2500, Fifty Year Canon of Solar Eclipses: 1986–2035 and Fifty Year Canon of Lunar Eclipses: 1986–2035. Fred is also co-author with Jean Meeus of the Five Millennium Canon of Solar Eclipses. Fred publishes eclipse and astrophotography resources at mreclipse.com and astropixels.com. Fred's calculations of eclipse Besselian Elements are the computational foundation for today's high-precision eclipse predictions and the maps on this website. Fred is a member of the International Astronomical Union Working Group on Solar Eclipses.
Bill Kramer collaborated with Michael Zeiler from 2009 to 2012 on a series of eclipse maps which can be found on Bill's website, eclipse-chasers.com and Michael's other website, eclipse-maps.com. The eclipse maps from this collaboration were the first to make corrections for the precise shape of the Moon using data from the JAXA/Kaguya laser altimeter device.
