1. A method comprising:

receiving, by one or more processors, location coordinates of vehicles driving on top of a second lift of a stockpile and making dumps on the top of the second lift of the stockpile,

wherein the second lift is a n+1 layer among many layers of the stockpile, and

wherein a height of the second lift extends from a top of a first lift to the top of the second lift;

aggregating and averaging, by the one or more processors, the location coordinates of the vehicles driving on the top of the second lift of the stockpile to determine a location of the vehicles driving on the top of the second lift of the stockpile;

receiving, by the one or more processors, elevation data measured from a bottom of the stockpile of the vehicles and from the location of the vehicles;

determining, by the one or more processors, a second elevation of the second lift from the bottom of the stockpile to the top of the second lift, based on the elevation data of the vehicles; and

determining, by the one or more processors, the height of the second lift from a top of a first lift to the top of the second lift, by deducting a first elevation of the first lift from the bottom of the stockpile to the top of the first lift, from the second elevation of the second lift from the bottom of the stockpile to the top of the second lift, wherein the first lift is a n layer among many layers of the stockpile.
