How to make an orthophoto with a drone ?

The use of drones in forestry is becoming more common practice around the world. They are used as an affordable, fast and accurate method of data collection. Drones can be used to assess deforestation, identify tree species, identify and monitor disease outbreaks, identify small fire sources, locate unauthorized landfills, assess forest resource losses after fires, natural disasters, and many other needs, including reforestation. In addition, drones have access to hard-to-reach areas, without which obtaining data would not be timely and costly.

Another area in which the use of drones is necessary is the updating of cartographic data. In contrast to labor-intensive ground-based mapping methods, unmanned aerial vehicles make it possible to quickly and cost-effectively perform aerial photography of areas in order to compile orthophotos.
