DT Aerial Services uses a drone with a high-resolution camera to collect 48 megapixel aerial photographs for creating orthomosaics. Put simply, an orthomosaic is like Google Earth, but way sharper. It is a large, map-quality image with high-detail and resolution made by combining many smaller images called orthophotos.
The key difference between a normal aerial photo and an orthophoto is the perspective and accuracy. A normal aerial photo has a perspective view. In photos you can see the sides of buildings and other objects, and the perspective changes depending on where the photo was taken.
An orthophoto, on the other hand, is what is called “orthorectified”. It is geometrically corrected for this perspective view, along with lens distortion and camera angle, to create a perfectly straight-down view of all objects in the frame as you would see on Google Earth.
One of the main use cases for an orthomosaic is simply to get an updated view of a large area of land. Google Earth is helpful, but often the imagery is outdated. Your new development project could be finished, new construction projects could be underway, or the landscape could have changed from natural disasters, land clearing, or anything else. In real estate an agent may also want an updated view of property. Whatever the reason is, orthomosaics are the perfect way to get an updated view of your land or structure.48-megapixel
