What is Orthorectification?
Orthorectification—a subtopic of georeferencing—is the process of converting images into a form suitable for maps by removing sensor, satellite/aircraft motion and terrain-related geometric distortions from raw imagery.

What is drone Mapper?
What Is Drone Mapping? Drone mapping is an aerial survey conducted by a drone and specialist cameras, which can include RGB (for photogrammetry), multispectral, thermal or LiDAR sensors. This method enables the collection of highly-accurate data, extremely quickly.
What are Orthomosaics used for?
Available with Advanced license. An orthomosaic is a photogrammetrically orthorectified image product mosaicked from an image collection, where the geometric distortion has been corrected and the imagery has been color balanced to produce a seamless mosaic dataset.
Why is Orthorectification needed?
The image data must be processed to remove distortion to set the precise location of an area. This process is called orthorectification. Without this process, you would not be able to make direct and accurate measurements of distances, angles, positions, and areas.
What is the difference between Orthorectification and georeferencing?
Georeferenced Versus Orthorectified Imagery A georeferenced image has no accuracy guarantee; and while often times there is an accuracy statement for this type of data, it is a global average and not an assurance. In order to assure the horizontal accuracy of an image, it needs to be orthorectified.
Is DroneDeploy free?
The DroneDeploy mobile app is free to use and all new users have a 14 day trial. The free trial DroneDeploy Explorer plan enables you to create 2D maps and 3D models without charge.
How do I create an Orthomosaic in Arcgis?
Generate an orthomosaic
- In the Ortho Mapping tab, In the Product group, click Orthomosaic.
- Click Next.
- In the Orthorectification Settings window, under the Elevation Source drop-down menu, choose DTM.
- In the Color Balance Settings, uncheck Select Mosaic Candidates and accept all other default options.
What software is used in drones?
Some of the top drone mapping software is as follows; DroneDeploy 3D Mapping Solutions. Pix4D Mapper Photogrammetry Software. AutoDesk ReCap Photogrammetry Software.

What is a drone Orthomosaic?
An orthomosaic (interactive drone map) is a geometrically correct aerial image that is composed of many individual still images that are stitched together. Orthomosaics provide a similar view to what you’d see in the satellite view in Google Maps.
What is Orthomosaic Photogrammetry?
An Orthomosaic Map is an aerial photograph comprised of dozens, hundreds, or thousands of smaller overlapping images, typically captured with a drone or UAV.
What is orthorectification and how does it work?
When stitched together with specialized software using a process called orthorectification, these images can be used to create a highly detailed, distortion-free map — and enhance the visibility of details that may not be visible using more common photogrammetry techniques.
Why use orthomosaic imaging for land surveying?
Across the board orthoimages and maps are useful for both detailed imaging and topographic accuracy. Whether you’re looking to use orthomosaic imaging for land surveying or one of its other wide-ranging applications, DJI has the ideal drones, camera payloads, and software for the job.
What drone mapping software do I need for my project?
In addition to using an automated flight path, you’ll need drone mapping software with orthomosaic capabilities, such as DJI Terra. With Terra you can generate a 2D orthomosaic of a set area in real-time — making it the ideal software for time-sensitive projects.
What is orthomosaic in DJI Terra?
The above orthomosaic was constructed in DJI Terra from 64 high-resolution aerial photographs Orthorectified imagery differs from standard aerial photographs in the way that it visualizes perspective. Orthophotos are corrected for perspective, camera tilt, and lens distortion.
