Topographic surveys, orthomosaics, DSMs and DTMs
We use the latest photogrammetry techniques to rapidly process UAV captured data
A range of applications
UAVs offer a data workflow that can be used by a wide range of industries and sectors
Our outputs have a number of use cases including tracking site and building progress, cut and fill (volumetric) calculations as well as a range of dimensionally accurate maps. We work for a range clients who are looking to survey large sites, those planning to develop new housing and infrastructure as well as those who simply want a point-cloud digital twin of their asset.
Accurate data capature
Expected outcomes are cm accurate when using Ground Control Points (GCPs)
You can expect precise mapping using accurate survey techniques with RTK GNSS and NTRIP correction. We use meticulous flight planning and sophisticated software to automate our UAV flights, minimising human error. This gives measurable results to RICs Survey grade D or E, even on large projects of 100+ Ha
Rapid turnaround
Our software allows for powerful and fast local or cloud-based processing
Using UAVs for data capture gives fast turnaround times compared to traditional mapping techniques and the first phase of deliverables are usually ready 24 hrs after the initial flight.
Deliverables and outputs
UAVs offer a number of benefits to traditional topographic mapping
Increased team safety
By entrusting the bulk data capture of a topographic survey to a UAV, surveyors no longer have to manually collect data in areas where the terrain or surrounding environment is dangerous. This makes the overall process far safer and keeps field professionals productive and safe on the ground.
Reduce overall survey time
Using a UAV, topographic surveyors can get an aerial view of the land they are surveying. UAVs, equipped with the right software and sensors can be used to greatly reduce the time needed to deliver highly accurate topographic survey mapping. Up to 100 ha can be surveyed in 1 working day.
Quickly verify accuracy
Ground control points (GCPs) with RTK / GNSS are crucial for ensuring the accuracy of a drone-led topographic survey. Using specialist software, our workflow links data capture, GCPs with accurately geolocated orthophotos and point clouds. We even include data check-points to demonstrate accuracy.
