Drone mapping services are our newest offerings for our customers. Drone mapping, also known as photogrammetry, is being used in a wide range of applications. The precision of the newest drones is amazing due to the onboard GPS. We now have software that can help us fly a precision mission to get the images you need. This allows us to create a map with a resolution of around 1 inch per pixel.
An orthomosaic map is a georeferenced single image that is stitched together using hundreds or thousands of overlapping images. The images are all corrected software using the camera and lens settings of the drone and ground control points. This geolocation technology helps us to create an image corrected map that is more accurate than using Google maps. It is also time-specific, whereas satellite images may be several years old. This is a game-changer for crop surveys and other time-sensitive data needs.
The image above is an area I mapped to show the results that come from the drone/software combination when doing a mapping mission. The image demonstrates a few of the different things you can do with an orthomosaic map.
This map is overlaid with a satellite view of the same area. As you can see, even though conditions have changed, the shorelines and streambed in the upper left corner of the map match up perfectly.
Another thing that stands out right away is that the satellite view was taken in the summer, while the map mission was flown in mid-December. You can have the same mission flown at intervals to see changes over time. Notice the difference in the water levels in the creek between the satellite photo and the orthomosaic map.
A problem with using satellite maps is that they are many times several years old. And the cost of updated satellite maps for the average farmer or business is prohibitive. Drone mapping is an affordable alternative to costly satellite photos.
Drone mapping services for real estate marketing can help increase your sales. The real estate industry is beginning to use orthomosaic maps in marketing properties. The typical altitude of an orthomosaic map mission is between 200 and 300 feet. This type of map can give potential buyers an idea of not only the property but also the surrounding neighborhood. These maps can also be used to do a 3d rendering of the area for potential buyers. The most successful real estate professionals are using this technology to drive sales.
Farmers can now make use of this technology to check on crop health and possible pest infestations. The process uses the multispectral abilities of drone cameras. The Visible Atmospherically Resistant Index (VARI) uses a stock camera that is included with most drones to measure the amount of green in an image using RGB images.
Relative crop health can be determined by measuring the amount of green light reflected back to the camera sensor and measuring the amount of green light compared to other wavelengths. Since plants reflect light mostly in the green portion of the spectrum (that’s why leaves look green to our eyes) a farmer can detect areas that may be having problems. The farmer can then investigate the area and solve the issue, thus potentially increasing yields. These areas can be detected from the air where they might be missed in spot checks of the field until they are in an advanced state.
Our drone mapping services can be used to create orthomosaic maps that are accurate enough to be used to measure volumes and areas. A good example of this is how this imagery can be used in the roofing industry to help determine the area of a roof. The data can then be used to determine with greater accuracy what materials will be needed for a job. This can help to refine estimates for customers which can assist you in landing more jobs when bidding. It can also be used when planning solar panel installations. Once installed panels can be inspected using drone technology. You can read more about inspections using drones here.
Another use of measurements available with these maps is in the mining and construction industries. These measurements using drone and software technology can give you accurate measurements when you don’t require a legal land survey but instead only need accurate data. I’m sure you can think of many more uses for this technology in your business.
Drone Mapping Services-3D Modeling
We can also produce 3D models of buildings, construction sites, properties, and other items. Using the same technology we can shoot your building or other sites to construct a 3D model in which you can fly around in 3D space. Spin and view your current model from any angle and gain valuable insights and data to make informed decisions.
