Aerial Topos and Drone Inspection Services

Using advanced PPK drone technology, we produce detailed, interactive maps of vast tracts of land. In just two years, we have created over 400 aerial topos for dozens of clients. Extreme Aerial can provide you with detailed drone videography that maps out thousands of acres at a high resolution, ready to send in an instant to engineers, land surveyors, cell companies and more.

Big Picture, Small Details

Since the new release of post-processing and real-time kinematic (PPK) drones in 2018, we’ve been able to up our game when it comes to creating aerial topos. When conducting drone inspections of large tracts of land, we apply this new technology to produce aerial topos to 1/10th of a foot or better—every time, and without ground control. Even though we always use ground control for ground truthing the models!


To create aerial topos of land tracts as large as 1000 acres and more, we use one of the fixed-wing aircraft in our fleet. These high-altitude drones allow us to produce aerial topos of land areas as large as 2800 acres, all to the finest detail.

Partnering with Engineers

The ability to map from the air large parcels of land, and at a very high definition, provides invaluable data for engineers. We work closely with engineers and send them data within hours that can easily be absorbed into Civil 3d, CAD, Agtek

From Inspection to Design—in Hours

Advanced drone technology means the time from inspection to design can be just hours. Using our aerial topos, engineers can start designing immediately. Then, they can validate their designs by comparing it with our maps. Aerial topos are extremely helpful when it comes to finetuning designs and planning large projects before a land purchase is complete.

Applications of Aerial Topos

Drones can be used to inspect nearly anything! Imagine that anytime a human would have to climb a ladder, a drone can be used instead. Drones are faster, safer and much more cost effective. Plus, drones are able to capture what they see on film, precluding human error and preventing the need for humans to double-check their estimates.


In the world of inspection, the rule of thumb is that only 15% of what is inspected ultimately needs to be repaired, maintained or replaced at any given time. But mandated annual or semi-annual inspections means that most infrastructure must be inspected. Using drones, these required inspections can be quick, affordable and completely safe.

Drone Inspection Clients

Here are examples of some of our inspection clients.


  • Cell Towers - We use our drones to inspect cell towers and confirm inventory. Our drones are able to zoom in close enough to read bar codes. In previous projects, our drones have identified cases where cell towers are compromised and that foreign equipment has been installed.

  • Substations - Extreme Aerials pilots are often hired to inspect substations and create a 3d model for expansion and assets verification.

  • Bridges - We use drone inspection to carefully assess bridges. Our videos can detect delamination, stress fractures, erosion and other major threats that face our aging bridges. For bridge inspection, we fly drones with top-mounted cameras and high-powered zoom. This way, we can confirm areas in need of repair, without having to interrupt traffic, close lands or use specialized equipment. After our flights, engineers use our data to identify where bridges need fixing and how to best implement the repair work.

  • Solar Panels - Drone inspection has many applications in the world of solar. We use our thermal cameras and mapping services to prove a solar installation is successful. We can also troubleshoot a solar array if it is performing below spec, confirm or log GPS coordinates, or conduct a panel inventory by location on large installation of solar panels.

  • Critical Infrastructures - Maintenance, preplanning of improvements and security of the facilities and the data collected are of utmost importance, so we use specialized equipment to facilitate most sensitive areas.

  • Agricultural Monitoring and Crop Inspection - By bringing together drone technology and the world of agriculture, we are able to help farmers in countless ways. This is an exciting, new application of drones can help farmers improve efficiency, reduce water usage, minimize stress on the environment and produce healthier crops. Here’s how it works: Farmers can hire Extreme Aerial to perform a weekly drone inspection of your clients. We can easily monitor 5000 or more acres using our state-of-the-art multispectral sensors. The images we collect can instantly provide you with detailed information about the rate of photosynthesis, water uptake, the health of your plants and - most importantly - potential infestation. Armed with this accurate data, you can develop a plan to treat small issues before they affect large amounts of your crops. Drone surveying can significantly reduce your costs, increase your yields and help you identify the perfect harvest times based on their crop, yield needed and location.
