UAV / Drone Surveys

Large sites, fast coverage, without putting anyone on difficult ground.

What are UAV / Done Surveys?

A UAV or drone survey captures aerial imagery and geospatial data over a site, then processes it into outputs such as orthomosaics, contours, point clouds, textured 3D models and digital terrain models.

For large sites, hazardous ground or areas that are awkward to access on foot, it is one of the quickest ways to understand what is there.

This is commonly used for feasibility studies, land promotion, masterplanning, stockpiles, earthworks monitoring, quarries, infrastructure corridors and broad development parcels.

It is also very useful where clients want both a technical dataset and a clear visual overview for reporting, stakeholder communication or phased progress monitoring.

The important point is that drone data is not a magic replacement for every other survey method.

If the design depends on precise service cover levels, hidden breaks in level, under-canopy detail, boundary evidence or dense local control, we will tell you that and combine the drone survey with ground survey.

That is usually how you get the best result: aerial coverage for speed, ground control and check shots for reliability.

Applications

Large development and regeneration sites
Feasibility studies and land promotion
Earthworks, stockpile and progress monitoring
Hazardous, contaminated or difficult-to-access ground
Broad context mapping for planners and design teams
Environmental and landscape studies
Combined aerial and ground control surveys for better coverage

Benefits

Covers large areas very quickly
Reduces time spent on difficult or unsafe ground
Produces useful visual outputs for client teams and stakeholders
Supports volumetrics, terrain analysis and progress comparison
Cost-effective for wide or open sites
Helps identify where targeted ground survey is still needed

Deliverables

Orthomosaic mapping
Digital terrain model (DTM) and / or digital surface model (DSM)
Point cloud or textured 3D model
Contours and CAD-ready mapping outputs
Volumetric calculations where required
Ground control schedule and accuracy notes

Why Choose Powers?

We do not oversell drones. We use them when they add real value, manage the data properly, and integrate the outputs with topo, DTM and engineering workflows so the dataset can move straight into design.
