MapInfo Pro

On August 21st, 2017 the United States will be treated to a Full Solar Eclipse. Here is the path of the best visibility shown in MapInfo Pro using various data sources.

See Attachment

You should have zipped and shared a MapInfo workspace with the geometry. People could then zoom in and find a specific city and see if that city were included in the totality.

Or use this site to find Eclipse events: http://www.pitneybowes.com/us/blog/location-data-offers-eclipse-insight.html

Here is a list of upcoming eclipses from Wikipedia: https://en.wikipedia.org/wiki/List_of_solar_eclipses_in_the_21st_century

I wonder about the challenges of mapping this. The magnitude of the eclipse from a given point on the ground declines as you move farther and farther from the path of totality. Sounds like an interesting raster based GIS problem. Some kind of raster buffer.

The Wikipedia page provides a single point location, a path width and some other info. It doesn't convey a path. Could one discern a path mathmatically?

Look at this video. They used the most detailed moon and earth models (with topography) to render how the shadow will move: https://www.nasa.gov/feature/goddard/2017/nasa-moon-data-provides-more-accurate-2017-eclipse-path
