01 / Acquisition design
Capture the right detail.
Design flight lines, tie lines and terrain following around the target and block. Synchronised ground-reference readings support correction for magnetic variation over time.
Aeromagnetic intelligence
Explore what the
surface can’t tell you.
Flybi connects drone-borne magnetic acquisition, geophysical processing and geological interpretation. Resolve the patterns across your block, review structural targets and give the next investigation a documented basis.
Geophysical interpretation
Read the signal.
Explore the structure.
Explore source-derived geophysical outputs, from mapped magnetic variation to the report’s subsurface models. Change the block, compare views, and inspect the detail.

Loading the numerical grid…
nT · Scale normalised per block
Drag to rotate. On touch screens, drag sideways; scroll vertically as usual. Display height represents magnetic amplitude, never ground elevation or depth.
Report views are source-derived excerpts with site-identifying labels withheld. Anomaly surface uses the supplied numerical RTE grids; it is a scalar visualisation, not a new inversion. Height and colour are normalised separately for each block.
Subsurface interpretations are non-unique and require geological validation. Magnetic response does not confirm mineral grade or reserves.
How the interactive surface uses the data
The source grids contain single-band floating-point magnetic values at 12.5 m spacing in the project coordinate system. The report’s RTE legends establish nanotesla (nT); scalar units are not embedded in the TIFF tags. The viewer samples the original grid at a regular stride and retains its final row and column. Values are transferred to 0.01 nT precision.
Blank cells remain blank. A displayed face is omitted if any original cell within its footprint is NoData (−99999); no gaps are filled and no new geological bodies are inferred. Surface height and colour use each block’s full value range, with a display-only relief control. Compare amplitudes using the numerical legend, not the apparent height between blocks.
The numerical asset loads only when you choose Anomaly surface. Report views remain available independently.
A stronger basis for investigation
From a broad block
to better-informed questions.
Magnetic variation can reveal contrasts and structures worth investigating. The useful result is an interpretation grounded in geology, not an assumption that every anomaly is a deposit.
02 / Processing
Keep the chain traceable.
Review line data, diurnal and regional-field corrections, levelling and gridding. Keep the correction history with the processed outputs so specialists can follow the chain.
03 / Interpretation
Build the next question.
Read magnetic domains, lineaments and suitable derivative maps alongside geology. Distinguish an interpreted target from a confirmed mineral occurrence.
Interactive explanation
Coverage comes first.
Interpretation comes next.
Move through the same conceptual block. The layers explain the workflow; they are not measurement results.
Illustrative block · no measured values01 / Coverage
Design around the question.
Flight-line coverage is designed around the block, target, terrain and required detail. Ground-reference data helps account for variation over time.
Line spacing here is illustrative, not a recommended flight plan.
Deliverables to agree
A reviewable package.
Not just a coloured map.
01 / Grids & maps
Explore the magnetic response.
Total Magnetic Intensity (TMI) and selected derivatives, such as analytic signal or vertical derivative, with coordinate and processing metadata. GeoTIFF and specialist grid formats are defined with the receiving geophysical team.
02 / Interpretation
See the geological reasoning.
Magnetic domains, interpreted lineaments and follow-up priorities, supported by maps and geological reasoning. Where a target memo is included, record coordinates, assumptions and the evidence still needed.
03 / Data & quality record
Understand how it was produced.
Line-data files, base-station records and a processing report that explains corrections, quality checks and exclusions. Define the raw-data handover and interpretation responsibility before acquisition.
How the work comes together
Define. Acquire. Interpret.
01 / Before mobilisation
Scope the block.
Share the boundary, target geology, access, available historic data and required outcomes. Agree acquisition design and permissions before fieldwork.
02 / In the field
Capture and check.
Acquire the planned lines and reference data. Review coverage and quality while there is still an opportunity to resolve gaps.
03 / At the review
Connect the findings.
Review magnetic maps and interpretation with the exploration team. Use existing outcrops, boreholes or other available evidence to prioritise follow-up and explain uncertainty.
Before you scope a block
The questions that matter.
Does a magnetic anomaly prove a mineral deposit?
No. Magnetic measurements respond to contrasts in magnetic properties. Geological interpretation and further evidence are required to understand a source and assess its significance.
How are line spacing and flight height chosen?
They depend on the target, expected geometry, terrain, required detail, operating permissions and campaign economics. A suitable design follows the block review; one fixed specification does not fit every site.
Can we commission acquisition without interpretation?
Flybi offers acquisition through interpretation. Tell us which stages your team will undertake so we can define the data handoff, correction records, formats and interpretation responsibility.
What information helps us begin?
A block boundary, target or geological question, terrain and access information, existing maps or borehole data, timing and preferred outputs provide a useful starting point.
