To survey a site with significant elevation change you will need to fly two different missions—one from the highest point and one from the lowest. You will also need to have ground control at each change in elevation. The two flyovers should then we processed into a single dataset.

How to Survey Elevation Change?
Surveying elevation changes is a crucial part of any land surveyor’s job. Elevation changes can affect the safety of construction projects, the accuracy of mapping, and the development of infrastructure. Elevation changes can also be used to monitor changes in the landscape and track land degradation or erosion. Knowing how to survey elevation changes is a key skill.
The most common way to survey elevation change is through the use of a total station. This instrument is a combination of a theodolite, a telescope, and an electronic distance measuring device. It is used to measure the angle between two points and the distance between them. A total station is used to measure the elevation change between two points by measuring the vertical angle between them and the horizontal angle from the instrument to the points.
When surveying elevation change, it is important to take multiple measurements from different points in order to get an accurate reading. It is also important to take readings in both directions, from the same point, in order to determine the slope of the terrain.
In addition to the total station, another instrument used to survey elevation change is the level. A level is an instrument used to measure the difference in elevation between two
