What an orthomosaic is An orthomosaic is a geometrically corrected "super-photo" created from hundreds of overlapping drone images. It has been processed to remove perspective distortion, meaning the scale is uniform across the entire map—allowing you to measure distances and areas directly from the image.
How it differs from a normal aerial photo A normal photo has perspective; the further something is from the centre, the more distorted it becomes. An orthomosaic is "orthorectified," making it act like a map where every pixel is correctly positioned in space.
When clients use orthomosaics - **Construction**: Planning site logistics, tracking progress, and communicating with stakeholders. - **Land Management**: Mapping large estates, forestries, or agricultural land. - **Utilities**: Mapping pipeline or cable corridors with high visual context. - **Infrastructure**: Documenting the "as-built" state of a site at the end of a project.
Accuracy and control considerations For simple visual planning, a standard drone GPS map is often enough. For engineering-grade accuracy, we use RTK (Real-Time Kinematic) drones and Ground Control Points (GCPs) to tie the map to the real-world coordinate system.
Deliverables and formats Orthomosaics are typically delivered as GeoTIFF files for use in GIS/CAD software, or as high-resolution JPEGs/PDFs for general site meetings and digital records.
Practical Considerations
— Drone operations are subject to airspace, weather, site access, permissions, nearby people and property, and operational safety requirements.
