Orthomosaic maps are a grouping of many overlapping images of a defined area which are processed to create a new, larger “orthomosaic”: a highly detailed, up-to-date map that is in true scale. But more than just being a nice high-resolution map, the meta-information within an orthomosaic map allows for point clouds, volumetrics, NDVI, 3D tours, and more.
This opens up endless possibilities as it allows anything from a virtual tour of your construction site via 2D or 3D maps for a visual progress report, as well as deliver up-to-date maps of your real estate to potential buyers, calculate raw materials on a construction site or easily conduct inspections over difficult terrain.
Using calibrated digital cameras, we can obtain high-resolution orthophotos with lower cost and higher flexibility than conventional aerial systems such as manned aircraft or satellites. One of the main features is the high repeatability, being able to perform multiple flights in the same place without a substantial increase in the total cost. Orthophotos can be used in a huge range of applications:
When a multispectrum camera is fitted to the UAV then it allows the acquisition of images in multiple spectrum bands; visible, near infrared, thermal, hyperspectral … These images can be post-processed for a wide range of information such as irrigation / fertiliser or vegetation health analysis. This is achieved by orthophotos being generated for each spectral band, resulting in a huge range of applications:
- Precision Agriculture
- Forestry Management
- Fire line Management
- Rapid deployment and data capture
- Resolutions accuracy of approximately 5cm/pixel (depending upon acquisition height)
- Can capture relatively large areas per flight
- Can be generated in different bands: visible, near infrared, thermal hyperspectral …
- Fast post processing time for final ortho-rectified
- When combined with Ground Control Points can overlay existing datasets
- Is used in a wide range of services where topography data is required
Planning with precise data is essential for accurate work
