This Drone Has A Price Tag Of A Flying House!
More and more drones are being used for recreation and commercial uses around the world. 1UP Aerial Drone Services (a new member of the Evergreen Chamber of Commerce) recently used a LiDAR Equipped Drone & 3D Modeling Software to innovate for the Engineering and Construction Industries.
The process of 3D modeling isn’t new. Most traditional methods use “boots on the ground” surveying or more recently drone photogrammetry. This is the science of taking measurements from photos. The result is typically some kind of map, measurements, or even a 3D model of some object or landscape feature. Many of the maps you use every day in your personal and work lives were created using photogrammetry and images taken from aircraft or satellites.
Modeling with drones is very similar to this, the main difference being the lower altitudes a drone can fly, and the tighter control one has over the platform itself. You get “instant” data. These key differences mean a user can capture much more data and higher quality images. But, when you combine a drone with photogrammetry or LiDAR technology, the entire process is enhanced tenfold.
LiDAR (Light Detection and Ranging) is a remote sensing technology that uses the pulse from a laser to collect measurements. These measurements are then used to create 3D models and maps of objects and environments.
The concept of drone 3D modeling possesses enormous potential for engineering, construction, agriculture, mining, infrastructure inspection, and real estate. Having a clear, accurate digital database or 3D model of your project area, complete with measurements, is advantageous for many uses.
How Does Aerial Imagery & 3D Modeling Work?
In drone 3D modeling, a LiDAR scanner is taken aloft by a suitable UAV, which is then flown in a predetermined autonomous pattern over the terrain or objects to be mapped. (Sidebar: It’s amazing to think about the current status of autonomous automobiles compared to UAVs. We are already taking autonomous UAV flights daily.) LiDAR modeling uses a laser scanning system with an integrated Inertial Measurement Unit (IMU) and GPS receiver that allows each measurement, or point in the resulting point cloud, to be georeferenced.
Each ‘point’ combines to create a 3D representation of the target object or environment. LiDAR maps can be used to give positional accuracy – both absolute and relative, to allow viewers of the data to know the exact location on the globe from which the data was collected, and how each point relates to other objects in terms of distance.
Data gathered from a LiDAR-equipped drone 3D modeling mission can be used to map entire regions down to the smallest detail, enabling users to accurately pinpoint features, structures, or areas of interest in perfect detail. Features and objects such as waterways, canals, lakes, rivers, road networks, bridges, even rocks, and vegetation, can be located and classified with exquisite accuracy.
What industries are using drones?
Frequently we are working with Real Estate, Engineering & Construction Companies who are at the forefront of the technology innovation curves.
Technological advances have made it efficient and cost-effective to take real estate drone photography and videos from drones, aka Unmanned Aerial Systems (UAS or UAV or Drone). Real estate professionals working with residential, commercial and land parcels can all benefit from the images and information obtained from using UAS technology. This imagery is an incredible tool for potential homeowners moving to a different city, buying a second home, or trying to streamline the research process necessary to buy a new home.
Many commercial properties or large parcels of land do not lend themselves well to traditional photography. Other UAS applications in real estate include general property due diligence, insurance inspections, appraisals, building management, and heat-loss imaging using thermal cameras.
To date, Goldman Sachs reports Real Estate in the top ten uses of commercial UASs (real estate represents 26 percent). You might be asking yourself if using drones for Evergreen real estate photography is viable even necessary for you to stay competitive or if it’s just a flash in the pan. Whatever you decide, drones are shaping up to be the next evolution in real estate marketing.
Here are a few things to think about if you’re either considering or already using drones for photographing your real estate in Evergreen.
Drones have more uses than you realize
For real estate brokers/agents, drone photography can show potential buyers a variety of details, including:
- Encompassing aerial views of the entire property and land
- Confirming the condition of the roof and other property features that are difficult to access
- What the drive home or the kids walk to school looks like
- The neighborhood and the surrounding area, including the home’s proximity to amenities
- Civic developments or local improvement districts (LIDs) that the buyer’s property taxes might contribute to
The most common task for LiDAR systems is surveying. When combined with the versatility of drones, the benefits over a typical boots-on-the-ground survey are significantly multiplied. Drones can fly where people or other vehicles find it impossible to go and stay for extended periods of time.
Both the engineering and construction industries rely heavily on accurate survey work. As the project becomes larger, more complex, or more remote, the difficulty in obtaining accurate survey data rises. Drones can safely go where people cannot, stay longer and do more with less equipment, and still provide exceptionally high-quality data.
Check out this example: How the “Water Advisors to the West” Used Drone 3D Modeling
The Applegate Group, known as the “Water Advisors to the West,” provides clients expertise in water planning, water rights engineering, water policy, and development of water infrastructure. This helps to ensure access to a continuous supply of clean, uncontaminated water for drinking, living, and recreational uses.
The Applegate Group obtained government grants from the Bureau of Reclamation and the Colorado Water Conservation Board which is part of the Colorado Department of Natural Resources. The grants were used to obtain topographic data for use in rehabilitating a 15-mile long canal that will ultimately provide more water for irrigation to farmers in the Fruitland Mesa.
1UP Aerial Drone Services and Drone 3D Modeling
The Applegate Group contracted with 1UP Aerial Drone Services to collect LiDAR data to develop LAS point clouds of bare earth surface data to estimate cut/fill volumes for a 15-mile-long ditch lining and reshaping configuration project that will serve more water to 5,000 acres near Crawford, CO.
1UP Drones along with HTS Advanced Systems flew a LiDAR equipped drone that is equivalent to the price of a small house ($250,000) over a very dangerous canal. This involved a large amount of flight planning, obtaining access to the canal, overcoming two days of snow and sleet, plus initially convincing the client that 1UP was able to execute the planned task.
This was the first LiDAR drone 3D modeling mission The Applegate Group had ever contracted, so the entire process was new, and they maintained a healthy amount of skepticism about the promised results. Moreover, the terrain was extremely treacherous, with wildlife, rock outcroppings, a deep canopy of trees and underbrush all being a concern.
What Were the Results?
In the past, the Applegate Group would have been forced to expend precious dollars, time, and manpower in a dangerous area. Kris Crawford of the Wilmore Land Surveying Company (who we worked very closely with) would have had to transport heavy equipment by 4-wheeler, and their plan was to capture every 100-foot transect leaving engineering extrapolation and guesswork for the canal between the 100 feet. Difficulty with the terrain would likely have prevented Kris from providing as much data for the survey as the UAV ultimately collected.
After viewing the results of the drone 3D modeling mission, Craig Ullman, VP, Applegate Group, said, “The 1UP LiDAR UAV data and precision equals fewer surprises and more accurate canal rehabilitation estimates.”
As a result of the data collected by 1UP through drone 3D modeling, the following crucial costs were controlled for improved construction and ultimately more water:
- Balance of cut/fill quantities
- Minimized shotcrete volume
- Minimized membrane requirements
- The Applegate Group expects to increase the canal water flow by 7 cubic feet per second and provide farmers an extra 2 weeks in the irrigation season
- More data and precision than what could have been accomplished with “boots on the ground” surveying
- 50% less time in data collection
- 25% less cost in data collection
How Can Drone 3D Modeling Help Your Real Estate, Engineering & Construction Projects?
Surveying for site preparation and other operations can be greatly enhanced with drone 3D modeling. Typically, engineering and construction firms don’t have the desire to invest the capital to operate an expensive drone with LiDAR, provide the resources for personnel to acquire the FAA Part 107 certifications, and provide for the insurance, risk, and daily expertise necessary.
Therefore, contracting with 1UP Drones makes for a great partnership with forward-thinking surveyors, engineers, and construction companies. 1UP provides the equipment and expertise for surveying missions, while engineering and construction companies gain highly accurate survey data for a variety of applications, with minimal personal investment compared to maintaining their own drone operations.
