Geographical distance or geodetic distance is the distance measured along the surface of the earth, or the shortest arch length The two cities used were alexandria and syene (modern aswan), and the distance between the cities was measured by professional bematists The formulae in this article calculate distances between points which are defined by geographical coordinates in terms of latitude and longitude.

The walking distance measure denotes the distance that can be travelled by walking in a fixed amount of time
In japan, the standard measure for walking distance is 80 meters for 1 minute of walking time.
A commonly used example is lloyd's algorithm Distance matrix, an array containing the distances (euclidean or otherwise) between any two points in a set This is frequently used as the independent variable in statistical tests of whether the strength of a relationship is correlated with distance, such as the volume of trade between cities. List of extreme points of the united statesthis is a list of points in the united states that are farther north, south, east or west than any other location in the country
Also included are extreme points in elevation, extreme distances and other points of peculiar geographic interest Extreme points in the 50 states Point barrow, ka lae, sail rock, peaked island extreme points in the. For example, if the nodes of the graph represent cities, and the costs of edges represent the distances between pairs of cities connected by a direct road, then dijkstra's algorithm can be used to find the shortest route between one city and all other cities.
The travelling salesman problem seeks to find the shortest possible loop that connects every red dot
Solution of the above problem in the theory of computational complexity, the travelling salesman problem (tsp) asks the following question Given a list of cities and the distances between each pair of cities, what is the shortest possible route that visits each city exactly once and returns.
