It is, also, known as L1 norm and L1 metric. It is used extensively in a vast area of field from regression analysis to frquency distribution. It was introduced by Hermann Minkowski. The concept of Manhattan distance is captured by this image:
Properties of Manhattan distance are: 1. There are several paths (finite) between two points whose length is equal to Manhattan distance 2. A straight path with length equal to Manhattan distance has two permitted moves: 2.1. Vertical (one direction) 2.2. Horizontal (one direction) 3. For a given point, the other point at a given Manhattan distance...
In a 2 dimensional space, a point is represented as (x, y). Consider two points P1 and P2: Then, the manhattan distance between P1 and P2 is given as: $$ {{|x1-x2|\ +\ |y1-y2|}$$
In a N dimensional space, a point is represented as (x1, x2, ..., xN). Consider two points P1 and P2: Then, the manhattan distance between P1 and P2 is given as: $$ |x1-y1|\ +\ |x2-y2|\ +\ ...\ +\ |xN-yN|} $$
Manhattan distance is a special case of Minkowski distance. When P=1 for Minkowski distance, we get Manhattan distance.
Manhattan distance is frequently used in: 1. Regression analysis: It is used in linear regression to find a straight line that fits a given set of points 2. Compressed sensing: In solving an underdetermined system of linear equations, the regularisation term for the parameter vector is expressed in terms of Manhattan distance. This approach appears...
Learn the definition, properties and formula of Manhattan distance, a distance metric between two points in a N dimensional vector space. See how it is used in regression analysis, compressed sensing and frequency distribution.
The Manhattan distance is a different way of measuring distance. It is named after the grid shape of streets in Manhattan. If there are two points, (,) and (,), the Manhattan distance between the two points is | | + | |.
Taxicab geometry or Manhattan geometry is geometry where the familiar Euclidean distance is ignored, and the distance between two points is instead defined to be the sum of the absolute differences of their respective Cartesian coordinates, a distance function (or metric) called the taxicab distance, Manhattan distance, or city block distance.
Learn what Manhattan distance is, how to calculate it, and why it is useful in machine learning and computer vision. See examples, code, and exercises on this concept.

The formula for Manhattan Distance is straightforward and involves summing the absolute differences between the coordinates of two points. Here's the formula: Manhattan Distance = |x1 - x2| + |y1 - y2|. In this formula: (x1, y1) represents the coordinates of the first point. (x2, y2) represents the coordinates of the second point.
