Distance calculation is the numerical expression of how far two points are from each other. In cartography, the distance between two points is divided into two as bird flight distance and road distance. Bird flight distance is calculated by drawing a straight line between two points. The length of this drawn line will give the distance value. The actual distance is obtained by multiplying this length by the denominator of the map scale.
The road distance varies according to the travel vehicle. In case of traveling by foot or vehicle, the required distance is the road distance. In order to calculate the highway distance;
- — All roads to provide transportation between two points,
- — It is necessary to know the characteristics of the roads (length, direction information, number of lanes, speed limit etc.).
