What to know

What to expect from aerial surveying & mapping

01

Photogrammetry vs LiDAR - which one, when

Photogrammetry stitches overlapping aerial photos into an orthomosaic and a point cloud. Cheaper, faster, beautiful imagery, good vertical accuracy in open terrain. LiDAR fires laser pulses to build a point cloud directly. More expensive, slower, but penetrates vegetation canopy to surface real terrain underneath and produces higher-fidelity edge detail. Pick photogrammetry for open construction / mining / civil; LiDAR for forestry, dense vegetation, fine-detail engineering, or anywhere you need bare-earth DTM under tree cover.

02

Survey-grade vs mapping-grade vs indicative

Survey-grade: ±20-50mm vertical accuracy, requires ground control points (GCPs) plus RTK / PPK drone positioning. Used for cut-fill, contract volumes, statutory boundary work. Mapping-grade: ±100-300mm, GCPs optional, RTK/PPK drone. Used for design intent, progress monitoring, planning. Indicative: ±0.5-1m, no GCPs needed. Used for visualisation, marketing, rough volumes. Cost roughly triples from indicative to survey-grade - only spec survey-grade when you genuinely need it.

03

Stockpile volumes and earthworks

Drone volume measurement is now standard practice on mining and large civil sites. A single 20-minute flight over a quarry stockpile yard gives you all volumes within centimetres of accuracy, monthly. Compare against a ground survey: hours of crew time, less safe, no permanent record. For earthworks progress, regular flights compared against design surface produce cut/fill heatmaps that drive payment claims and progress meetings.

04

Deliverable formats and downstream workflow

Common outputs and their formats: orthomosaic (GeoTIFF), point cloud (LAS / LAZ), digital surface / terrain model (GeoTIFF), contours (DXF / Shapefile), volume calculations (PDF report + CSV), 3D mesh (OBJ / FBX). Civil and mining workflows usually want LandXML, Trimble / Topcon / Leica formats - name your CAD / GIS / fleet-management system in the brief and operators export accordingly.

Aerial surveying & mapping — frequently asked questions

Do you need ground control points (GCPs)?+

For survey-grade work, yes - typically 3-5 well-distributed GCPs per site, established by a licensed surveyor. For mapping-grade with a PPK / RTK drone you can often skip them. The operator advises in the bid.

How big a site can you survey in a day?+

Multi-rotor RTK: 50-200 hectares per day depending on resolution. Fixed-wing VTOL: 400-1,500+ hectares. LiDAR: similar to fixed-wing photogrammetry but with denser point clouds. Larger sites get multiple days, often with overnight processing in between.

How much does volume measurement cost vs ground survey?+

Drone volume work is typically 70-90% cheaper than equivalent ground crew time, and the deliverable is repeatable / archivable. Most operators run a monthly retainer for active sites that's cheaper than per-flight pricing.

Can the data drop into our machine systems?+

Yes - name the destination system (Trimble, Topcon, Leica, John Deere, Caterpillar) in the brief. Operators export to whatever the receiving system needs.
