Baseline
Fix a dated, cloud-free reference state for the concession, corridor or reserve, reconciled with the boundaries on record.
Ghana aerial monitoring / Capability 03
SkyGhana™
Turn every flight into an operating decision.
Repeat aerial capture, automatic change detection and tolerance-based alerts for mines, corridors, farms and cities.

Operating model
One site.
A cadence that holds.
Ghana loses ground between reports — a pit widens, a track appears, a buffer is crossed. SkyGhana fixes how often you look, what counts as a change, and who has to act when it happens.
Cadence design
Set revisit intervals from how fast each change actually happens, what it costs to miss it, and how much cloud the region throws at you.
Sensing stack
Combine wide-area optical screening, tasked high-resolution capture, all-weather radar continuity and UAV survey where centimetres matter.
Detection
Compare each capture against the baseline and the previous epoch; measure the changed footprint rather than describing it.
Verification
Route flagged patches to ground inspection, geotagged photography or UAV survey before anything is called an incident.
Escalation record
Deliver a dated change log, measured areas and volumes, imagery pairs and the escalation trail to the responsible authority or asset owner.
Sensing layers
Every layer states
what it cannot see.
Wide-area optical (10 m class)
Low-cost standing coverage of whole concessions and corridors.
Limit: Cannot resolve single structures or narrow tracks.
High-resolution optical (30–50 cm, tasked)
Tasked capture for structures, encroachment and evidence-grade detail.
Limit: Tasking is competitive and cloud-dependent; acquisition is not guaranteed on a given day.
Radar / SAR (all-weather)
Sees through cloud — the continuity layer through Ghana's rainy months.
Limit: Limited for buildings, colour and fine boundaries; interpretation is specialist work.
UAV / drone survey (2–5 cm)
Centimetre evidence, volumes and orthomosaics over a defined site.
Limit: Requires GCAA authorisation, a licensed pilot, site access and safe airspace.

Service boundary
Detection is evidence, not enforcement.
SkyGhana detects, measures and dates change and routes it to the responsible party. Enforcement remains with the Minerals Commission, EPA Ghana, the Forestry Commission, the Water Resources Commission, district assemblies and the asset owner. UAV capture is flown only under Ghana Civil Aviation Authority authorisation by a licensed remote pilot.

Ghana-first coverage across all 16 regions, subject to tasking availability, weather and airspace authorisation.

Vegetation and canopy loss
Trigger: Change patch ≥ 150 m² persisting across two consecutive captures
Escalation route: Forestry Commission

Resolve before the first capture
Priority 01
Refresh and certify the baseline
A dated baseline causes false positives from change that predates the mandate. Re-capture and reconcile against existing records.
Priority 02
Cadence cannot meet the required response window
The current design delivers an escalation in about 7 days against a target of 3 day(s). Add radar continuity, standing UAV cover or accept a longer window.
Priority 03
Add radar continuity through the cloud-affected months
Modelled optical obstruction in the Forest (bimodal rains) is around 64%. Radar keeps the record continuous when optical capture fails.
Build stage / the chain
Nothing here
stands alone.
SkyGhana™ answers “What changed since the last look?”. It produces the dated capture epochs and change alerts — and that record is exactly what the next desk refuses to work without.
