Precision drone mapping & aerial application · South Africa

Precision from above.
Impact on the ground.

We map, treat and monitor landscapes with data-led drone operations built around water security, biodiversity and smarter land management.

Capabilities

One aerial platform.
Many better decisions.

From first flight to final dataset, every operation is designed around the land, the outcome and the people who need to act on it.

01

Precision application

Survey-guided aerial treatment for invasive alien plants in steep, wet or difficult terrain—delivered with repeatable flight parameters, controlled spray windows and minimal ground disturbance.

Invasive plantsAerial applicationHard terrain

02

Mapping & survey

High-resolution corridor mapping, orthomosaics, terrain models and geospatial records that turn complex sites into clear, measurable operational plans.

03

Environmental intelligence

Machine-learning-assisted target identification, multispectral insight and repeat monitoring to prioritise work, measure response and guide follow-up treatment.

04

3D & volumetrics

Accurate 3D site models, stockpile measurements and progress documentation for construction, mining and land-management decisions.

How we work

We don't just fly a site.
We close the loop.

01

Map

Capture the site at operational resolution and establish a defensible baseline.

02

Plan

Translate terrain, species and risk into a practical treatment or survey plan.

03

Act

Fly precisely, work efficiently and document every operation as it happens.

04

Prove

Return to measure results, identify gaps and inform the next intervention.

Why it matters

Technology is only useful
when the
land responds.

Water security

Restore catchment function by treating thirsty invasive plants at landscape scale.

Biodiversity

Give indigenous vegetation the space and time it needs to recover.

Fire resilience

Reduce invasive biomass and the fuel loads that intensify wildfire risk.

Case study · Kammanassie River

Precision aerial control of invasive Black Wattle.

An 18-month, multi-phase programme targeting Acacia mearnsii across the Kammanassie River corridor in the Western Cape. Earth Drones combined high-resolution survey, machine-learning-assisted target mapping, precision aerial application and post-treatment monitoring in steep and access-constrained riparian terrain.

Reported Phase 1 efficacy
01

The operational challenge

Black Wattle occurred as fragmented and locally dense infestations along a long perennial river corridor below the Kammanassie Nature Reserve. Uneven terrain, restricted ground access and proximity to agricultural land required mapped targets, controlled flight planning and repeatable treatment records.

02

The response

Survey data was converted into treatment polygons so application could be limited to identified canopy. The programme was delivered in phases, allowing the team to return after canopy response was visible and focus Phase 2 on survivors and coppice regrowth.

01

Survey

DJI Mavic 3 Enterprise capture at approximately 1–2 cm ground sampling distance.

02

Map

Orthomosaics and ML-assisted classification used to define target canopy and flight blocks.

03

Treat

Low-altitude precision application with DJI Agras T40 ZT-000396 across mapped polygons.

04

Verify

Follow-up mapping 8–9 months after Phase 1 identified survivors and informed mop-up work.

Recorded production

942 L

total mixed spray volume across 27.90 ha of mapped treatment area

Outcome interpretation

Phase 1 efficacy was reported at more than 90% during follow-up assessment. The result indicates strong initial control, while also confirming that systematic surveillance and targeted follow-up remain necessary because survivors, coppice and the existing seed bank can re-establish the infestation.

About Earth Drones

Local field knowledge.
Aerial perspective.

Earth Drones is a South African environmental and geospatial operations company based in the Klein Karoo.

Led by David Rogers, our field team combines licensed aerial application, commercial drone operations, conservation experience and practical GIS workflows. We work where conventional access is slow, costly or unsafe—supporting catchment restoration, precision agriculture, surveying and environmental monitoring.

Field operations

Built for the places
the road can't reach.

From farms and dams to mountain catchments, Earth Drones combines practical field access with the aerial tools needed to see, treat and document difficult terrain.
