Survey & GIS
Photogrammetry
Photogrammetry is the science of combining multiple overlapping images to create a single overview image and 3D model of an area or object. TerraDrone use this technique by capturing overlapping imagery from cameras mounted on drones. The drone can be flown manually or pre-programmed to follow a defined route along which the camera takes images at defined points. This data is passed on to data processing teams in our offices who then process this data to produce single overview images and 3D models. By combining data with GPS control from the site the team can produce data with known levels of accuracy which are reported alongside the data delivery.
The output file formats from this process can be varied and offer clients a great deal of versatility and insight. Data can be viewed in almost any GIS or CAD software package.
LIDAR
Lidar is a surveying method that measures distance to a target by illuminating that target with a laser light and measuring the return signal. The difference between the time the pulse was sent and when the pulse was received is an indication of the distance of the target. The LiDAR sensor perform this task hundreds of thousands of times per second as the drone flies. The result is a high-density point cloud which provides a 3 dimensional representation of the area flown.
The subsequent LiDAR data can be further analysed to measure the intensity of each return signal from which our data analysts can use to classify the point cloud.
