Circumnavigation

A Path Variant

A Circumnavigation is a generic term for a Path that encircles the outside or inside of a recognisable geographical feature.

A Circumnavigation is also a variant of a Circumnavigation Path.

The appearance of Loops and Circumnavigations may sometimes overlap. Contact PECS if you require advice on how to determine your journey's path.

CIRCUMNAVIGATION

A Circumnavigation:

  • encircles the outside of a recognisable geographical feature
  • includes at least 90% of its expanse
  • starts and ends at the same point
Examples:
  • Circumnavigation of the Drygalski Mountains
  • Circumnavigation of the Greenland Ice Divide
  • Circumnavigation of Svalbard






.

PARTIAL CIRCUMNAVIGATION

A Partial Circumnavigation:

  • encircles the outside of a recognisable geographical feature and..
  • includes less than 90% of its expanse, or..
  • starts and ends at different points
Example:
  • Partial Circumnavigation of Greenland



.

INNER CIRCUMNAVIGATION

An Inner Circumnavigation:

  • encircles the inside of a recognisable geographical feature
  • includes at least 90% of its expanse
  • starts and ends at the same point

Example:

  • Inner Circumnavigation of Lake Baikal




.

PARTIAL INNER CIRCUMNAVIGATION

A Partial Inner Circumnavigation:

  • encircles the inside of a recognisable geographical feature, and..
  • includes less than 90% of its expanse or..
  • starts and ends at different points

Example:

  • Partial Inner Circumnavigation of the Greenland Ice Sheet



8-Point System

Where a perimeter or area cannot be measured the route should contact the feature's cardinal extremes (northernmost, southernmost, westernmost and easternmost) and an additional 4 points to form 8 touching points spaced evenly around the perimeter. The start/end point may be one of the 8 points.



GREENLAND CIRCUMNAVIGATIONS

.

Circumnavigation of Greenland

A Circumnavigation of Greenland encircles the outside of the island.

A Partial Circumnavigation of Greenland encircles less than 90% or starts and ends at a different point.

.

Inner Circumnavigation of the Greenland Ice Sheet

An Inner Circumnavigation of the Greenland Ice Sheet encircles the inside of the perimeter of the ice sheet, following the 8-Point System guidelines.

A Partial Inner Circumnavigation of the Greenland Ice Sheet encircles less than 90% or starts and ends at a different point.

.

Circumnavigation of the Greenland Ice Divide

A Circumnavigation of the Greenland Ice Divide encircles the Ice Divide including its extreme north and south points. See Definitions - Ice Divide of Greenland.

A Partial Circumnavigation of the Greenland Ice Divide encircles less than 90% or starts and ends at a different point.
