Digital aerial photography is playing an increasingly important role in the management of the natural environment and built infrastructure, and is now a part of everyday life with online mapping portals and use in the media. AeroPhoto Co Ltd is specializing in the acquisition of ultra-high-resolution aerial imagery and the processing and creation of high-quality products such as orthophoto maps and 3-D models. Orthoimagery or orthophoto is a remotely-sensed imagery that has been geometrically corrected (orthorectified) to adjust for lens distortion, camera tilt, and topographical relief. The resulted uniform scaled image is an extremely accurate view of the earth’s surface, allowing for the measurement of true distance, precise digitization, and the exact placement of geographic symbols.

Our orthophotography products and services are useful for many GIS base mapping applications, since they provide geospatially accurate visual representations of the earth. We can execute aerial survey missions with large format digital aerial camera with full photogrammetric nadir (straight-down) and oblique capture capabilities. In strong cooperation with our partners, we offer cost-effective solutions to wide area aerial surveys which are impossible, difficult or expensive to access or complete, using conventional terrestrial or satellite-based solutions.

AeroPhoto Co Ltd, has extensive experience and offers the following solutions and enhanced data products with exceptional degree of detail and accuracy:

Orthophoto production (orthorectification, mosaicking, color balancing, seem line correction)
Aerial triangulation, orientation & block adjustment
Stereo compilation (3D restitution)
DEM/DTM generation – 3D visualization
Planimetric features
Contour generation
3D city modelling

By investing in the latest technology, we ensure that the quality, accuracy, and consistency of digital aerial imagery is of the highest standard.

Applications for ortho imagery range from web directories and online services, mapping and engineering companies that use high resolution imagery for asset management and route planning, or even to governments for urban planning. AeroPhoto Co Ltd is using Vexcel Ultracam Eagle Μ3 digital photogrammetric nadir camera with an ultra-large footprint coupled with a unique user-exchangeable lens system, allowing for one frame per 1.5 second and offering the possibility to capture 10 cm GSD at 5,000 m above the ground. The camera features an unrivaled 26460 pixels across the flight strip summing up to 450 mega pixel per image. Meanwhile, the latest CCD technology using a pixel size of 4.0 µm leads to a larger footprint and more efficient flying.

The ability to simultaneously collect R, G, B and NIR channels at a rapid frame rate produces high quality multipurpose data suitable for a variety of applications such as agriculture/crop science, engineering design, cadastral maps and environmental assessment. Combining the know-how and the ability to operate with one of the most versatile airborne systems on the market, we are able to meet the most demanding requirements regarding accuracy, altitude, resolution and deliverables.

Oblique Imagery

Georeferenced oblique imagery extends the benefits of traditional vertical aerial imagery by providing a unique perspective view of a locality. In particular, oblique imagery solution offers high degree of detail and the advantage to evaluate any urban area from at least four different views in addition with the vertical solution, also known as bird’s-eye view. As a result, end users are able to measure distances, slopes and heights from the office, and get valuable information about buildings such as number of floors, access and backyard layouts, materials, advertising panels or to integrate vector data, while saving processing time and significantly reduce the need for field inspections.

As an integral part of every topographical, architectural survey and urban planning, from the documentation to decision making, the need for oblique imagery in day-to-day operations is now ever increasing. Moreover, it offers a cost-effective solution to wide area urban surveys which are impossible, inaccessible or expensive to complete using conventional systems. Oblique images comprise the main core of the basic production process of the 3D city models, and when combined with vertical images they ensure high-accuracy and fidelity deliverables such as DSMs, true orthophotos and imaging products of large cities.
