Orthomosaics

Historically, orthomosaics are typically created for the use of geographic surveys. This used to be a painstakingly difficult, lengthy, and expensive process. Now, equipped with a drone and the proper software, the cost of creating an orthomosaic has just hit rock bottom. This opens the door for so many other industries to take advantage of the information that orthomosaics can provide. 

If you fly a drone straight up to 400 feet, and take a picture straight down, you get an aerial photo. It may look like a great photo to hang on your wall but that's about all you can do with it. Since the photo is taken from only one position, perspective distorts uniformity of the picture and it is not a real and accurate representation of what's below. An orthomosaic is extremely useful because it is made up of many pictures that have been taken directly above and all around the entire area being photographed.

Software then takes all those pictures (all georeferenced) and stitches them together into one extremely high definition interactive multi-dimensional orthomosaic. Creating an image in this way allows for the rectification of uniformity. In other words, you can measure from one point to another and get an accurate representation of real world distances and perspectives. This is important when a drone inspects the roof on a house for hail damage, for example. Since the adjuster can now measure your roof accurately, they can estimate the amount of the claim without ever having an adjuster set foot on it.

 

A great real-world example of how orthomosaics are being used is in law enforcement. In Mesa County, Colorado, UAS program director Ben Miller has deployed drones to film outdoor crime scenes in extreme detail. This is a level of detail they have never had before, and provides an exceptional sense of relativity while also being able to zoom in on small things such as a bullet casing on the ground or even tire marks on a road. This creates a big-picture view of the entire scene instead of hundreds of regular photographs. Given that Mesa County was the first law enforcement entity to use orthomosaics, Argus Rising and Mesa County Sheriff's Office are currently working together to share knowledge and make this groundbreaking technology available to law enforcement across the country.

There really is no limit to how orthomosaics can work to benefit other industries as well. This video below shows a simple orthomosaic. It is easy to see how this could be used for a crime scene, surveying, construction planning, the list goes on! While the technology is still young, it's developing and getting better each day, and is already proving it's value in many industries!
