Topographical or Geopolitical mapsets?

Until 2015, the Geochron had only been built around a Geopolitical mapset.   As world history changed, so did the map.   It’s a map the represents the world by human boundaries…which change, like East and West Germany, the USSR, and recently North and South Sudan.   The geopolitical mapsets in every clock we build or re-build are current with world conditions today.

The Topographical mapset shows the earth like “view from the sky”.  Indeed, the satellite imagery composited into an entire map of the world is stunning.  Rather the human view, this is the Earth of the last 10,000 years, with several dozen large cities shown for reference.    The muted contours of the ocean bottom are visible too in this map.  (Early prototypes showed ocean bottom in full scale, which we decided was too overwhelming.)

Both maps show

  • The precise time zone lines
  • Major longitudes: the Prime Meridian (Greenwhich)
  • Major latitudes: Equator, Tropic of Cancer, Tropic of Capricorn
  • Topographical reliefs of the land.
  • A Mercator Projection

Why is it called a mapset?

Every Geochron ever made actually contains three maps, hand spliced together in a loop six feet long (1 inch x 24 time zones x 3 maps).  This allows the map to continuously scroll, at one inch per hour, as long the sun is rising or setting.  Essentially, forever!

Combining Geopolitical and Topographical mapsetsMixed mapset close up - web

Can you combine them?  Yes.  There are three maps in every Geochron, repeating the loop every three days.  Order a Geochron with 2 Geopolitical and 1 Topographical (or vice-versa), and you’ll see a Topographical mapset pass through every third day!
