Drone LiDAR Survey & Mapping

BlueCap provides drone LiDAR survey and mapping services for mineral exploration, mining and infrastructure across Australia and worldwide. The BlueCapLidar® drone LiDAR system and long-endurance aircraft connect acquisition to classified point clouds, bare-earth terrain models and reviewable QA.

BlueCap Survey Portal

Define the survey area, plan routes, develop a quote-ready scope, follow field acquisition and keep processed results and deliverables in one connected project workspace.

01

BlueCapLidar® Payload

Dual-sensor point clouds, four-IMU data, RTK positioning and flight telemetry remain connected in the same synchronised field record.

02

BlueCapHeli® Carrier

The hybrid petrol-powered carrier provides 3 or 8 hours of endurance, field refuelling and a normal 100 km/h cruise speed for productive survey acquisition.

03

Cloud Post-Processing & Automated Workflow

The BlueCap-controlled cloud service filters and stitches point clouds, runs terrain processing, classification and QA, and packages consistent automated deliveries.

04

BlueCap Survey Team

Geophysicists, remote pilots, engineers and post-processing specialists work as one accountable survey team from mission planning through acquisition, QC and delivery.

• A typical deployment includes at least five core personnel plus approximately 5–10 local spotters.
• AI-assisted tools accelerate repeatable processing and add a verification layer; experienced geophysicists remain responsible for final QC and every client deliverable.

LiDAR survey cost, schedule and market comparison

Estimate indicative LiDAR survey pricing, flight line-kilometres and field duration, then compare the commercial effect of productive area per flying day. This service view fixes the planning basis at 180 m parallel LiDAR line spacing; terrain, overlap, turns, required point density and a dual-orthogonal second pass are confirmed in the project quotation.

The public BlueCap reference combines an approximately A$160k project price with the single-pass acquisition basis shown below. Compare the required density, accuracy, ground returns and classification before comparing daily area. Three BlueCapHeli® systems are shown separately as a throughput option, not as the A$160k configuration.

Comparable high-density performance

Compare density, accuracy and daily area together.

A crewed aircraft can map thousands of square kilometres per day when collecting low-density regional elevation data. That is not equivalent to a detailed survey targeting approximately 50 points/m² and centimetre-level acquisition accuracy. The useful comparison fixes the deliverable first, then compares daily coverage, mobilisation and project cost.

Three independently planned low-altitude blocks combine regional production with local deployment, terrain following and operation beneath higher cloud layers. Dual-orthogonal acquisition can tighten the stated accuracy further when the project requires it.

Effective survey swath

Sensor and altitude dependent

At comparable high density and accuracy, lower altitude, narrower swath, reduced speed or added overlap reduce the headline coverage available from low-density regional flying.

In the indicative scenario, BlueCap is A$90–240k lower while targeting approximately 50 delivered pts/m², 3–5 cm XY and 4–8 cm Z in the single-pass mode — a denser, more precisely defined terrain product than the 4–8 pts/m² aircraft examples.

Density and absolute accuracy are separate measures, so both are stated. The three-system row compares available daily throughput only; the ≈A$160k reference uses one BlueCapHeli® across two flying days. Replace the crewed scenario with a current quotation and require the same density, accuracy, ground-return, classification and mobilisation scope before procurement.

Why the BlueCap price holds

Productivity changes the commercial result.

Long missions

Long-endurance sorties keep useful acquisition time high.

Fewer base moves

Less repositioning and fewer return-to-base cycles across the block.

Two flying days

The 330 km² reference block is planned across two productive field days.

More area per mission

Approximately 165 km²/day on the comparison basis.

One workflow

BlueCap owns acquisition, processing, QA and delivery as one system.

01Productivity first

Radius turns included~180 m line spacing

Parallel single-pass

One set of parallel flight lines, typically spaced about 180 m apart. This is the production-first pattern for broad areas and more open terrain.

Field output

~180–540 km²/day

Point density

~40–80 pts/m² ~100–120 pts/m² where geometry and speed support it

Best fit

Broad-area acquisition where field productivity is the priority. Particularly well suited to flat, lightly vegetated terrain such as deserts and open Western Australian bushland, where a single viewing axis meets the terrain-product requirement.

02Surface understanding first

Radius turns included90° second pass

Dual-orthogonal

The complete block is flown twice: one full parallel grid, then a second full grid at 90°. Crossed coverage adds a second observation axis across every part of the site and four viewing directions rather than two.

Line design

Two complete grids Project-equivalent north–south + east–west coverage

Field output

~90–270 km²/day

Point density

~100–250 pts/m²

Ground

Why the second full grid matters

Complementary pulse paths reduce direction-dependent occlusion behind tree crowns, scarps, rock faces, slopes and structures. They improve the opportunity for ground returns, make point geometry more uniform and support more stable classification and reconstruction of façades, outcrops and complex terrain.

Reference trade-off against single pass: field output is about half; density moves from ~40–80 to ~100–250 pts/m²; XY from 3–5 to 1.5–2.5 cm; Z from 4–8 to 2–4 cm; and canopy Z from ≤10–15 to ≤7 cm. These are project-design targets, not a universal probability of ground detection.

LiDAR before magnetics

Why LiDAR comes before a magnetic survey

BlueCapLidar® first measures terrain, canopy and obstacles. That surface becomes a calculated magnetic drape used by BlueCapHeli®, BlueCapWinch® and the suspended QuSpin QTFM Gen 2 as one acquisition-control system.

100 m AGLLiDAR surface model

Calculated drapeterrain · canopy · obstacles

>20 mcarrier–sensor separation

1. 01

   Map the surface

   BlueCapLidar® records a 285 × 160 m instantaneous window at 100 m AGL and builds the terrain and obstacle model.

2. 02

   Calculate the drape

   Terrain, canopy and obstacles become a flyable sensor-height profile; 35 m sensor AGL is a common reference in difficult tropical and subtropical relief.

3. 03

   Control the sensor

   BlueCapWinch® actively manages the QuSpin QTFM Gen 2 while maintaining more than 20 m carrier-to-sensor separation.

4. 04

   Fly and verify

   Speed control and sensor-AGL QA follow the calculated surface to target a 1 m terrain-following corridor before interpretation.

Controlled field evidence

Field experiment: terrain-following error can masquerade as geology

BlueCap repeated one controlled vertical profile at four separate field locations. BlueCapHeli® ascended above a QuSpin QTFM Gen 2 suspended on a pre-measured 20 m line while the stripped tubular bird rotated freely at each 25–50 m sensor-AGL level. Every height refers to the sensor above ground, not carrier altitude.

   RepeatabilityFour locations

   The response was repeated across separate sites rather than inferred from one location.

2. 02
   Horizontal controlOne fixed point

   The carrier held horizontal position while only sensor-to-ground distance changed.

3. 03
   Vertical control25–50 m AGL

   The helicopter increased height in one upward sequence; the 20 m suspension length remained fixed and sensor AGL was measured by range LiDAR.

4. 04
   Airframe separationMore than 20 m

   The magnetic sensor never came closer than 20 m to the BlueCapHeli® airframe.

Sensor too highanomaly is attenuated and spectrally shifted

Interpretation boundary: the chart below normalises the 35 m response and applies the first-order relationship across the tested 25–50 m range. It interprets the controlled experiment; it is not the unpublished raw time series.

Processing and delivery

Processing and deliverables

The engineers responsible for BlueCapLidar® also control its MCAP/MavROS 2 post-processing workflow. That connection keeps each LiDAR mapping requirement close to the payload, acquisition record and final terrain products.

Commercial impact for exploration projects

Remote-project cost is driven by flyable hours, deployed crew days and repeat visits — not only the sensor day rate.
