# PTH

* The **PTH** Path option will measure the path distance between sequential points anywhere on the active map layer. 
* Much like the Position option, it will also extract the X, Y, and Z coordinates as well as the capture time. 
* To choose a point on the active map layer, simply activate the **PTH** tab and click on a point on the active map layer.

![Measuring path distance in PTH option in SpatialExplorer](/files/-LSzqgv3yFe_Oh6D0T08)

* To define a path, a minimum of two points are required. 
* The path length will be displayed in the lower left corner with units of meters. 
* The path length is measured sequentially; this means that the length is calculated by adding the previous path length to the next path length. 
* Adding three or more points to the path length will simply add the path distance between all points.
