Here’s my top 5 ways drones are changing real estate:
Better maps and immersive 3D scenes
Drones capture images at very high resolution compared to aerial survey and satellites. For low level flights an individual pixel could be measuring an area as small as one inch square or less; many times more accurate than other sources. Using only still imagery and GPS data, analysis software can stitch the photos together to produce full color, photo realistic 3D datasets that provide immersive visualization and powerful analytics. You get a video game-like visualization experience that allows the viewer to fly around the model, exploring any part of it from any angle and the ability to measure any part of it.
The same data also produces 2D maps that can be superimposed on existing views, allowing organizations and individuals to get the most up-to-date and accurate view of the real world on demand.
Site planning, modeling, and survey
Drone flight post processing and mapping software lets operators calculate lengths, heights, areas and volumes without resorting to expensive and complicated ground surveys. A drone with suitable cameras, can survey a building or site in under an hour producing a terrain surface from which you can calculate and measure cut and fill volumes, slopes and aspect. This lets you estimate potential engineer work requirements and costs and see the impact using the same 3D visualizations described above.
Drone surveys can even detect hidden landscape features which are not obvious on the ground due to vegetation or ground cover. In the image below the walls of an abandoned building can be seen which were not visible on the ground due to unmown grass. Drones can also cover more ground than a survey, easily capturing nearby features and surveying hard to access features like streams and culverts.
Safer and remote inspections
Inspecting roofs, warehouses, industrial building, bridges and other assets can be a difficult and dangerous task. Many risk their lives every day to perform roof and building inspections.
Why not send a drone to take pictures instead? Autonomous drones let you plan and control the images collected so you can see the assets from all angles and distances, especially in situations that are too risky to get to in person.
Thermal cameras and other sensors let you look at how separate parts of a building gather and shed heat during the day and a night. Differences show up as variation in color identifying places that are losing heat, potentially due to inadequate insulation, or are colder. Nighttime and early morning surveys can easily be conducted by drones without endangering lives. Scheduling regular inspections using the same flightpath will identify wear and tear, highlight change and help with preventative maintenance.
Security and protection
Many companies rely on physical, electronic and human security protection. Not only can drones go where humans can’t but they can do it more consistently, in any weather condition, any time of day or night. The same cameras which are used for inspection can provide real-time security monitoring and improved coverage. Drones can be continually scheduled to patrol the skies above and around buildings while the operators remain safe and at a distance. Thermal cameras provide coverage in the dark, rain or fog and change detection analysis can show differences between two flights, highlighting potential security breaches or risks.
Indoors and more
Small drones are now flying indoors. They deliver similar inspection and security services as their big brothers outside. Indoor drones can provide 360-degree monitoring, cover areas that security cameras cannot and can easily be tasked with different roles at different times of the day or year. Thermal cameras, change detection, surveys and volumetric monitoring have applications as broad as compliance and security, to theft prevention, health and safety and stock control.
Real applications, right now
The full impact of the drones is only just beginning to be recognized. Improved simplicity and sophistication in both the drones and supporting software are providing huge improvements in the usability and usefulness of drones. Behind the hype of package delivery and flying warehouses are simple applications that are driving real innovation and financial benefit – from improved building security and reliability to keeping staff safe.
