Updated On: November 7, 2022

With the advent of newer and more sophisticated drones, mapping with drones has become increasingly popular in recent years. Drones offer a cost-effective and efficient solution for mapping large areas quickly and accurately.

There are many different ways to use drones for mapping, and the best method for you will depend on your specific needs and application. In this article, we’ll give you an overview of the basics of drone mapping and how to get started.

Defining Drone Mapping

Basics of Drone Mapping

Drone mapping is the process of using drones to capture photographs of an area, which are then stitched together to create a 2D or 3D map. This map can be used for various purposes, such as surveying land, inspecting infrastructure, or even planning agricultural fields.

Mapping itself is self-explanatory – you are taking many pictures from different angles and positions and then stitching them together to create a map.

The hard part is getting accurate measurements from these photographs so that the map can be used for specific purposes, such as surveying land areas or measuring distances.

However, with the right software and some practice, it is possible to create highly accurate maps using drones. The accuracy of drone-based maps is often comparable to that of traditional ground-based surveying methods such as GPS.

Methods of Drone Mapping: Photogrammetry and LiDAR

Basics of Drone Mapping

There are two main methods of drone mapping – photogrammetry and LiDAR (Light Detection and Ranging).


Photogrammetry is the process of using photographs to create 2D or 3D maps. This is done by taking multiple pictures of an area from different angles and then using special software to stitch these photos together. The software will also calculate distances and sizes based on the photographs, which can then be used to create accurate 2D or 3D maps.


LiDAR is a newer technology that uses lasers to measure distance. A LiDAR sensor is mounted on the drone, and as the drone flies, the sensor emits pulses of laser light. These pulses bounce off objects in the environment and are then captured by the sensor.

By measuring the time it takes for the pulses to bounce back, the LiDAR sensor can accurately calculate distances. This data is then used to create 3D point clouds, which can be used to create highly accurate 3D maps.

GCPs, RTK, and PPK

Basics of Drone Mapping

To create accurate maps, it is necessary to use Ground Control Points (GCPs), which are defined points on the ground with known locations. These points are used as reference points when stitching together photographs or calculating distances from LiDAR data.

Another way to create highly accurate maps is to use a Real-Time Kinematic (RTK) system. This GPS-based system uses a base station to provide real-time corrections to the drone’s GPS signal. This allows the drone to know its exact location at all times, which can be used to create very accurate maps.

A third way to achieve accuracy is through Post-Processed kinematics (PPK). This is similar to RTK, but the corrections are calculated after the drone has flown rather than in real-time. This method can be used if you cannot access a real-time GPS signal.


Since GPS position accuracy is often restricted to around 2 to 5 meters, even at maximum satellite coverage and employing the most powerful GPS technology, ground-level correction is required for high-level mapping applications. The geographic precision of the data can be improved up to a centimeter-level by employing any of the three ways below.


This GPS-based system uses a base station to provide real-time corrections to the drone’s GPS signal. This allows the drone to know its exact location at all times, which can be used to create very accurate maps.


The abbreviation PPK stands for “Post-Processed Kinematic.” It’s similar to RTK in that it uses an onboard PPK module and a fixed ground base station.

In terms of technology, there isn’t much of a difference between the two types. of systems. The main distinction lies in the way that the data is processed.

With RTK, the position information is transmitted in real-time from the base station to the drone. This allows for corrections to be made on the fly during the mapping process. PPK, on the other hand, doesn’t transmit any data in real time.

Instead, the data is processed after the fact, using the information from the base station and the actual GPS data that was collected by the drone during its flight.

This may seem like a disadvantage, but PPK has some benefits that make it a more attractive option for certain mapping applications.

Perhaps the biggest benefit is that PPK doesn’t require a real-time data connection between the base station and the drone. This means you can fly in areas without cellular coverage or another type of data connection.

Fixed-Wing vs. Multi-Copter

Basics of Drone Mapping

When it comes to drone mapping, two main types of drones can be used: fixed-wing and multi-copter. Choosing the right type of drone for the job is important, as each has its advantages and disadvantages.


Fixed-wing drones are more efficient when flying for long periods since they don’t have to constantly fight against gravity as multi-copters do. These drones are well-suited for large areas, such as fields or farms. However, fixed-wing drones are more difficult to control and are not well-suited for mapping in tight spaces.


On the other hand, multi-copter drones are much easier to control and can fly in tighter spaces. They are also better suited for taking high-resolution photographs, making them a good choice for mapping small areas or detailed structures. However, multi-copter drones have shorter flight times and are not well-suited for mapping large areas. They are also more maneuverable.

What Software is needed?

Basics of Drone Mapping

To create a drone map, you will need some specialized software. There are a few options available, but the most popular are Pix4D and DroneDeploy.

  • Pix4D is powerful mapping software that can be used to create 2D maps, 3D models, and point clouds. It is compatible with a wide range of drones and cameras and offers a variety of features, such as automatic flight planning and photogrammetry. This software is a good choice for more experienced users.
  • DroneDeploy is another popular mapping software that offers similar features to Pix4D. It is also compatible with a wide range of drones and cameras. However, it has a simpler interface that is more user-friendly for beginners.
  • Pix4D and DroneDeploy offer free trials, so you can try each one to see which works better for you.
  • Other than this, make sure you also have a good quality camera, such as the GoPro Hero 7 Black, to get started.

Richard J. Gross

Hi, my name is Richard J. Gross and I’m a full-time Airbus pilot and commercial drone business owner. I got into drones in 2015 when I started doing aerial photography for real estate companies. I had no idea what I was getting into at the time, but it turns out that police were called on me shortly after I started flying. They didn’t like me flying my drone near people, so they asked me to come train their officers on the rules and regulations for drones. After that, I decided to start my own drone business and teach others about the safe and responsible use of drones.
