Drone Photogrammetry 


Drone photogrammetry is a technique that uses   drones to capture aerial imagery and data that can be used to create 3D models and maps. The process involves using a drone equipped with a camera to capture a series of overlapping images of a specific area or object from different angles.


The images are then processed using specialized software that uses algorithms to stitch together the overlapping images into a 3D model or map. This process is called photogrammetry and relies on the principles of triangulation, which involves using multiple points of reference to determine the location and position of objects in space.


Drone photogrammetry has a wide range of applications, including surveying, mapping, urban planning, agriculture, and environmental monitoring. It is particularly useful for creating highly detailed and accurate 3D models and maps of areas that are difficult or dangerous to access on foot, such as construction sites, mines, and disaster zones.


One of the main advantages of drone photogrammetry is its ability to capture high-resolution imagery quickly and efficiently, allowing for rapid data collection and analysis. This can lead to cost savings and improved accuracy compared to traditional surveying and mapping methods.


However, drone photogrammetry also requires careful planning and execution, including ensuring that the drone is flown within legal and safety guidelines, and properly processing and analysing the data to ensure its accuracy and usefulness.


Below is a video of a 3D model constructed for Oakley Hall Hotel near Basingstoke which was scanned and mapped by using our photogrammetry workflow.

Digital Surface Models (Photogrammetry)


Digital Surface Models (DSMs) and Digital Elevation Models (DEMs) have various use cases across multiple industries. DSMs and DEMs are used to create accurate representations of the Earth's surface, capturing elevation data and creating detailed topographic maps. They are essential for land surveying, urban planning, and infrastructure development.


They can play a crucial role in various industries, providing accurate elevation data for decision-making, planning, and analysis in fields ranging from engineering and environmental management to agriculture and renewable energy. They can help indicate how water may act on the land. Comparison over time can show changes in land features such as cliffs, ridges or sinking.


The image below is a basic DEM. They uses heat map colours to indicate differences. Here reds are higher elevation and blues are lower with greens in-between:

Digital Terrain Models with Contours


Digital Terrain Models (DTMs) show a projection of the ground relief and can assist with relative level surveys of land.


The image below is a basic DTM with contours at 1m intervals. The heat map colours indicate differences:

Volume and Other Measurements


Photogrammetry can be used to take accurate measurements of a model in digital space. This can be useful in many applications including measuring stockpiles or planning site clearance and earthworks.
