Distances between coordinates Now that it’s clear how to describe the position of points in Earth, let’s say you want to calculate the distance between two of them.
distance between two points on the surface of the Earth, in terms of their respective latitudes and longitudes. This is an interesting exercise in spherical coordinates, and relates to the so-called haversine.
The Haversine formula gives the "as-the-crow-flies" distance, i.e., the great circle distance along the surface of the earth. If you take the Euclidean distance between two points in $\mathbb{R}^3$, you are finding the straight-line distance, which will cut through the earth.
This article shows how to determine the exact linear distance between two points using their coordinates. Geographic coordinates. The Earth's surface resembles the surface of a sphere. Each point on the earth's surface can thus be uniquely described by two coordinates: latitude and longitude.
Less common but still very important are the cylindrical coordinates (r, θ ,z). There are a total of thirteen orthogonal coordinate systems in which Laplace’s equation is separable, and knowledge of their existence (see Morse and Feshbackl) can be useful for solving problems in potential theory.
Distance The use of coordinates as developed in Section 9.3 allows us to analyze many properties of geometric figures. For example, we can find distances between points in the plane using coordinates. Consider points P(x1, y1) and Q(x2, y2) (Figure 15.1). We can use point R(x2, y1) to form a right triangle, nPQR. Notice that the length of the ...
