In short

Are you an MSc student in Geomatics, Computer Science, or a related field looking to apply your knowledge to the energy transition? Vattenfall offers a thesis project in data fusion, combining satellite, drone, and sonar data to create high-resolution bathymetric maps and 3D reconstructions. This temporary, on-site role in Solna/Älvkarleby, Sweden, is ideal for students with strong Python programming skills and experience in machine learning.

Responsibilities

Develop a data fusion approach combining satellite imagery, drone imagery/photogrammetry, and ROV sonar measurements.
Produce accurate, high-resolution bathymetric maps for a shallow water area.
Investigate machine learning/deep learning methods for aligning, calibrating, and merging data sources.
Combine fused bathymetry with above-water elevation and terrain data for a full 3D reconstruction.
Estimate water volume of the area.
Conduct literature review on relevant surveying methods and data fusion techniques.
Acquire and pre-process multi-source data.
Develop and apply a data fusion model.
Perform elevation and terrain analysis.
Evaluate and validate the fused bathymetry model performance against ground-truth measurements.
Carry out field campaigns to collect validation data.

Requirements

Enrolled in an MSc programme in Geomatics, Remote Sensing, Computer Science, Applied Physics, Environmental or Civil Engineering, or a related field.
Strong written and verbal communication skills in English.
Strong programming skills in Python.
Experience with data analysis and relevant tools such as NumPy, PyTorch, TensorFlow, GDAL, Rasterio, or GIS software.
Knowledge of, or a strong interest in, remote sensing, image processing, machine learning, and deep learning.
Basic understanding of GIS principles and geospatial data formats, including raster data, point clouds, and coordinate systems.
Ability to work independently, structure and document work systematically, and communicate results effectively.

Desired Qualifications

Swedish language skills are considered an advantage.
Interest in applying satellite-based data to environmental analysis and biodiversity-related challenges.
Experience working with satellite imagery, drone data, or sonar/acoustic survey data is considered an advantage.

Benefits

Opportunity to complete a thesis project close to the business.
Work alongside experienced specialists.
Tackle challenges where your ideas and perspectives can make a real difference.
Gain practical experience in data fusion and the energy transition.
