Aerial Survey Services

An Orthophoto map is a  seamless digital photographic image of an area, created from aerial photographs. They are created by taking high resolution aerial images and draping them over a Digital Terrain Model (DTM) using AutoCAD Civils software to create perfectly true to scale aerial images. Each image is then mosaiced and colour balanced to provide a high-quality photographic image.

Where access is restricted or safety issues are a concern, we can produce highly accurate topographical maps from aerial photographs when traditional survey methods are not possible. Photogrammetrically produced maps can also be very cost-effective for topographical mapping of large areas.

Using on board High-Resolution digital cameras makes a copter the ideal drone for carrying out inspection surveys of any structures with limited access. We can carry out inspection surveys on buildings, bridges, pylons, tanks and provide High-Resolution images and videos that can be viewed, zoomed and analysed to identify any structural issues or damage. This can include identifying roof damage on a church, corrosion on electricity pylons or developing cracks in high-rise buildings, the possibilities are endless.

Aerial LiDAR surveys utilise high-powered laser scanners to capture thousands of points every second and can cover hundreds of hectares during each flight. Airborne LiDAR has a real advantage over terrestrial photogrammetry resulting from its ability to penetrate through vegetation and tree canopies and provide a complete model of the landscape. Where large areas of Topographical Survey data are  required, Aerial LiDAR really is the most cost-efficient way to acquire your Digital Terrain Model and when combined with ground control points, LiDAR data can provide highly accurate and comprehensive topographical surveys and digital terrain models in a fraction of the time to carry out a traditional Topographical Survey.
