# Finding the location of a point on a line using linear referencing

The use of linear referencing is widespread, ranging from storing bus routes to oil and gas pipelines. Our ability to locate any position along a line based on a distance value from the start of the line is done using the interpolation methodology. We want to interpolate a point location at any position along a line. To determine the position, we'll use simple mathematics to calculate the position along a line based on the distance from the starting coordinate.

For our calculation, we'll measure the length of the line and find a coordinate located at a specified length from the start of the line. However, the question of where the start of the line is will soon arise. The starting ...
