Interpretation of cause and damage remains with the relevant assessors, investigators and engineers.
Typical use

- Vegetation indices
- Crop variability
- Plant-health investigation
- Trial monitoring
- Field comparison
- Seasonal change
Typical use
- Crop variability
- Vegetation indices

- Targeted scouting
- Seasonal comparison
Orthomosaic
1/2
Sample survey — drag from the orthomosaic to the same view with surface contour lines.
Sample survey — orthomosaic base map of the full stream section, bridge to bridge.
Point cloud
1/2
Sample survey — channel, bank slopes, bridge and adjoining structures as a 3D model.
Full stream section
1/6
Sample survey — drag to zoom from the full stream section down to the stream bed and bank vegetation at full resolution.
Sample survey — debris collecting along the channel, identifiable at full resolution.
Environmental Monitoring
Repeat aerial datasets for environmental consultants, researchers, conservation organisations and land managers.
Applications include:
- Rehabilitation monitoring
- Vegetation change
- Erosion
- Wetland and river conditions
- Land-use change
- Habitat documentation
- Environmental baseline surveys
Delivered as
- GeoTIFF maps
- Point clouds
- Contours
A single survey provides
- Baseline mapping
- Channel and bank condition
- Riparian vegetation extent
- Debris and litter
- Surface model for specialist flood and erosion work
Repeat surveys from the same flight plan add change comparison, such as bank erosion, vegetation and rehabilitation progress.
Examples are a sample survey of a public river area, shown to demonstrate the data products.

An independent capture specialist
I work independently and can support projects as a dedicated drone operator or as part of a wider technical team.
This works particularly well for companies that require professional aerial data occasionally but do not need to employ and maintain an internal drone operation.
I can operate alongside:
- Engineering teams
- Surveyors
- Environmental consultants
- Agricultural specialists
- BIM and modelling teams
- Project managers
- Construction teams
- Building consultants
The technical interpretation remains with the relevant professional while I focus on collecting the best possible source data for the task.
Operational capability in detail
Professional Drone Operations. SACAA-licensed Remote Pilot with experience operating across commercial, construction, residential, agricultural and infrastructure environments.
Complex-Site Capture. Experienced in operations requiring coordination with site teams, controlled access, roof launches, restricted operating areas and active construction environments.
Repeatable Data Collection. Flight planning and capture methods can be standardised for projects requiring comparison across multiple visits.
Remote & Field Operations. Available for projects throughout the Western Cape and for project-based deployment elsewhere in South Africa or further afield where required.
My approach
I provide specialist drone and field data capture for projects where accurate, repeatable or hard-to-access visual information is required.
My work supports contractors, engineers, project managers, survey teams, BIM specialists, property consultants, environmental professionals and agricultural teams by gathering high-quality source data for their existing workflows.
The focus is on the capture itself: planning the operation correctly, collecting the right data, maintaining consistency across repeat visits and supplying usable datasets to the professionals responsible for analysis, design, measurement or decision-making.
With a background in construction inspection and quality assurance, I understand that useful drone data needs to do more than look impressive. It needs to clearly record the condition, location or change being investigated.
Let’s define the capture requirement
Tell me what you need to see.
If you have a site, asset or area that needs to be mapped, documented, inspected or monitored, send me the project location and what your team needs to achieve. I can help determine the most appropriate capture method and whether drone data is suitable for the project.
