What is a Waypoint?

• Waypoints are locations or landmarks worth
  storing in your GPS. These are locations you may
  later want to return to. They may be check points
  on a route or significant ground features.
• Waypoints may be defined or obtained in the field
  or by taking coordinates for the waypoint from a
  map or other reference. This can be done before
  ever leaving the office.
