An orthomosaic map is a type of high-resolution, georeferenced aerial image that has been stitched together from numerous individual overlapping photographs or images ( Photogrammetry) . These images are usually captured from different angles and positions using Drone Photography and Video to cover a specific area from multiple perspectives.
The key characteristic of an orthomosaic map is that it has been geometrically corrected, or "orthorectified," to remove distortions caused by the Earth's curvature, camera angle, topography, and lens aberrations. This correction process ensures that the resulting map has consistent scale and minimal distortion throughout, allowing it to be used for accurate measurements, analysis, and mapping purposes.
Orthomosaic mapping is widely used in various fields, including agriculture, forestry, land surveying, urban planning, environmental monitoring, disaster response, and more. They provide a detailed and accurate representation of the landscape, which can be valuable for making informed decisions and conducting analyses that require precise spatial information.
Note: The orthomosaic maps created by Ashlar Aerial serve as tools for visualization and discussion purposes. It's important to understand that these maps do not serve as a substitute for professional surveying. Nevertheless, they can be valuable to your surveyor as a visual tool during conversations about the extent and details of your surveying undertaking.
