2. Triangulation (surveying) - Wikipedia

   en.wikipedia.org/wiki/Triangulation_(surveying)

   In surveying, triangulation is the process of determining the location of a point by measuring only angles to it from known points at either end of a fixed baseline by using trigonometry, rather than measuring distances to the point directly as in trilateration. The point can then be fixed as the third point of a triangle with one known side ...

3. Haversine formula - Wikipedia

   en.wikipedia.org/wiki/Haversine_formula

   d is the distance between the two points along a great circle of the sphere (see spherical distance), r is the radius of the sphere. The haversine formula allows the haversine of θ (that is, hav(θ)) to be computed directly from the latitude (represented by φ) and longitude (represented by λ) of the two points:

4. Great-circle navigation - Wikipedia

   en.wikipedia.org/wiki/Great-circle_navigation

   Great-circle navigation. 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 ...

5. Triangulation - Wikipedia

   en.wikipedia.org/wiki/Triangulation

   Measuring the height of a building with an inclinometer. Triangulation today is used for many purposes, including surveying, navigation, metrology, astrometry, binocular vision, model rocketry and, in the military, the gun direction, the trajectory and distribution of fire power of weapons . The use of triangles to estimate distances dates to ...

6. Magnetic declination - Wikipedia

   en.wikipedia.org/wiki/Magnetic_declination

   Magnetic declination (also called magnetic variation) is the angle between magnetic north and true north at a particular location on the Earth's surface. The angle can change over time due to polar wandering . Magnetic north is the direction that the north end of a magnetized compass needle points, which corresponds to the direction of the ...

7. Scale (map) - Wikipedia

   en.wikipedia.org/wiki/Scale_(map)

   The scale of a map is the ratio of a distance on the map to the corresponding distance on the ground. This simple concept is complicated by the curvature of the Earth 's surface, which forces scale to vary across a map. Because of this variation, the concept of scale becomes meaningful in two distinct ways.
