How Aerial Imagery Is ChangingOur View of the World

When natural disasters happen, it’s hard to grasp the extent of the devastation from the ground. When images surfaced from the 2017 hurricane season that damaged Texas and Florida, the most revealing shots were those taken from above. Aerial imagery captured by drones and other aircraft revealed the full story of the disaster on the ground.

Even amidst the great loss of life and home, disasters have a strange way of bringing about innovation. As humans faced tragedy, new ideaswere birthed from chaos. In areas of Florida and Texas, they put aerial drone images side by side of the region before the hurricane and after the damage was done. Emergency planners, residents, and business owners could compare what remained in place and what was completely gone.

Aerial drone imagery also offers solutions for business in far less stressful situations. From it, you can gather data which supports property-specific information about what’s happening on the ground. Aerial imaging can detect property changes, characteristics, assess liability risks, and even estimate damage.

Essentially, the technology can help assess trends over time. Images can improve our understanding of risk factors for residential or commercial properties and surrounding businesses. Aerial imagery can also offer critical information about the effects of traffic, weather, natural disasters, and more.

The main sources for high-resolution aerial imagery come from satellites, airplanes, drones, and mobile devices. While each has their own advantages and limitations, they all offer accurate and dependable data about a location when integrated. Data from all sources can be fed into information dashboards to create analytics for a range of uses.

Cameras and sensors mounted to low-flying aircraft often provide higher resolution aerial imaging than satellites up in space. Aerial platforms on planes make it possible to take oblique images because it can take pictures at 45-degree angles as well as orthogonal images. If you’re measuring square footage, roof slope, stories, and elevation heights, oblique shots are effective at providing information on new structures and other changes. They help create true 3D property models.

As soon as drone’s hit the market, their popularity exploded. The commercial aerial drone market has doubled nearly every year in the U.S. and companies are now using drones for surveillance, deliveries, and surveying crops. Some drones can be equipped with lighter or heavier cameras for more versatility and are relatively inexpensive.

Data and imagery from drones can also be used to create 3D models and take pictures of various terrain. When combined with software, the data and images can detect weather patterns and estimate damages to structures.

As innovations in the sky evolve and improve, we’ll continue to see advances in responses to disasters and inspecting property damage. Aerial imaging is the wave of the future and the future is looking up.

At Insitu, we develop commercial and military aerial drones and software to gather data from the sky. Contact us to learn more.
