Aerial Survey Services

An Orthophotomap is a  seamless digital, map accurate vertical photograph 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 ERDAS IMAGE software to create perfectly true to scale aerial images. Each image is then mosaiced and colour balanced to provide a high quality map accurate photograph.

Where access or safety issues are important we are able to produce high accuracy 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 had to reach structure. 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 carried on aircraft or helicopters to capture thousands of points every second and can cover hundreds of square Kilometres during each flight. Airborne LiDAR has a real advantage over terrestrial photogrammetry in that it can penetrate through vegetation and tree canopies to 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. High accuracy ground control is an absolute requirement to enable an accurate fix of your LiDAR data.
