Great-circle navigation or orthodromic navigation (related to orthodromic course; from Ancient Greek ορθός (orthós) 'right angle' and δρόμος (drómos) 'path') is the practice of navigating a vessel (a ship or aircraft) along a great circle. Such routes yield the shortest distance between two points on the globe. [1]
The Great Loop is a system of waterways that encompasses the eastern portion of the United States and part of Canada. It is made up of both natural and man-made waterways, including the Atlantic and Gulf Intracoastal Waterways , the Great Lakes , the Erie Canal , and the Mississippi and Tennessee-Tombigbee Waterway .

A diagram illustrating great-circle distance (drawn in red) between two points on a sphere, P and Q. Two antipodal points, u and v are also shown. The great-circle distance, orthodromic distance, or spherical distance is the distance between two points on a sphere, measured along the great-circle arc between them. This arc is the shortest path ...
The Crimson Route was a planned Great Circle route to ferry aircraft from manufacturing plants in Southern California and Seattle via Montana over Canada to Greenland using Arctic air routes. This route had the advantage of avoiding the poor weather over the North Atlantic by flying over the high latitudes of northern Canada to Greenland, then ...
This is a List of Ontario Tourist Routes throughout the province, which are designated to highlight places of cultural, environmental, or social importance.. It is currently unknown if the majority of these trails are still listed since many of the provincial highways of Ontario were decommissioned in 1997 and 1998, as the Tourist Trails followed the provincial highways for the majority of ...
The Great Lakes Circle Tour is a designated scenic road system connecting all of the Great Lakes and the St. Lawrence River. [1] It consists of routes for circumnavigating the lakes, either individually or collectively.
Pilots use aeronautical charts based on LCC because a straight line drawn on a Lambert conformal conic projection approximates a great-circle route between endpoints for typical flight distances. The US systems of VFR ( visual flight rules ) sectional charts and terminal area charts are drafted on the LCC with standard parallels at 33°N and 45°N.
The route paralleled the CPR for 135 miles (217 km) west of Winnipeg before it veered northwest. [11] That year, the provinces of Alberta and Saskatchewan were established. The line proceeded west to Saskatoon in 1907, Edmonton in 1909, and Wolf Creek in 1910. [ 12 ]
