You provide the imagery or spatial data.
I review, process, validate and prepare the outputs.
Photogrammetry GIS Point Clouds 3D
Wrocław, Poland Remote / international collaboration
I work with UAV imagery, point clouds and spatial datasets you already have. Depending on your project, I can prepare mapping and 3D outputs, process GIS data, or automate repetitive tasks—with quality checks and clear notes on the results.
Focused processing support for your imagery and spatial data.
Turn supplied UAV imagery into mapping and 3D outputs, starting with image quality checks and dataset preparation.
Review and prepare point clouds for further analysis, comparison or use in your GIS workflow.
Prepare consistent spatial data for mapping and analysis, with checks on geometry, attributes and coordinate systems.
Make repeatable GIS tasks easier to run with scripts tailored to your data and processing requirements.
Suitable outputs are agreed after reviewing the source data and your requirements.
Dataset review comes first, so we can agree a practical scope before processing begins.
Share your imagery, point cloud or spatial dataset, along with the intended use and outputs you need.
I assess the inputs, identify gaps and discuss suitable outputs, limitations and the processing scope with you.
I prepare and process the data using a workflow suited to the dataset and agreed requirements.
I check the outputs for completeness, consistency and processing artefacts, and document relevant limitations.
You receive the agreed outputs in suitable formats, with notes on processing, checks and any limitations that affect their use.
Source-data quality, coverage and capture geometry, available metadata and georeferencing, and your project requirements. I review these together before we agree which outputs the dataset can support.
Technical case studies in dataset review, processing and interpretation—with findings and limitations documented.
UAV photogrammetry / 3D reconstruction
Image quality checks and dataset selection guided a comparison of photogrammetric reconstruction strategies. The work combined automated and manual image review, capture-geometry assessment, WebODM processing, and point-cloud and model inspection.
A smaller, more coherent dataset produced a more useful reconstruction than a larger mixed dataset.

No RTK positioning or surveyed ground control points (GCPs) were used. Absolute accuracy was not verified to survey-grade standards.

UAV photogrammetry / GIS
Image and EXIF review, manual image selection and WebODM processing supported orthophoto, surface and terrain outputs, relative-height analysis and 3D reconstruction. Nadir-only and nadir-plus-oblique results were compared.
Adding oblique imagery improved façade and 3D reconstruction compared with nadir-only imagery.

No RTK positioning, surveyed GCPs or independent checkpoints were used. Absolute positional accuracy was not independently verified.

UAV data processing / QA
A UAV dataset processed through image quality checks, WebODM reconstruction and GIS review. The work covered orthophoto, surface and terrain models, a dense point cloud and 3D reconstruction.
Processing setups were compared to evaluate output consistency and document the workflow from source imagery to reviewed outputs.

I’m an independent specialist based in Wrocław, Poland, focused on UAV and geospatial data processing. I work remotely and collaborate on projects in Poland and internationally.
My technical background includes approximately seven years of professional experience with DJI UAV systems: diagnostics, repairs, troubleshooting, fault isolation, warranty assessment, technical documentation and post-repair quality control.
