Thesis Work: Data Fusion for Bathymetric Mapping

Agriculture, Energy & Environment · Environmental Services · Sustainability Consulting

In short

As a student, you can complete your thesis project at Vattenfall, developing a data fusion approach to create high-resolution bathymetric maps by combining satellite, drone, and sonar data using machine learning. This project supports the energy transition and offers a unique opportunity to work with experienced specialists on real-world challenges.

Responsibilities

  • Develop a data fusion approach combining satellite imagery, drone imagery/photogrammetry, and ROV sonar measurements.
  • Produce accurate, high-resolution bathymetric maps for areas subjected to water regulation for hydropower.
  • Investigate machine learning/deep learning methods for aligning, calibrating, and merging heterogeneous data sources.
  • Develop a unified depth map using sparse ROV measurements for correction and validation.
  • Combine fused bathymetry with above-water elevation and terrain data for a full 3D reconstruction of the basin.
  • Estimate the water volume of the area using the 3D reconstruction.
  • Conduct a literature review on relevant surveying methods and data fusion techniques.
  • Acquire and collect satellite, drone, and ROV data.
  • Pre-process and co-register multi-source data to a common spatial and depth reference.
  • Perform elevation and terrain analysis.
  • Evaluate and validate the fused bathymetry model performance against ground-truth measurements through field campaigns.

Requirements

  • Student about to complete academic studies.
  • 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.
  • Basic understanding of GIS principles and geospatial data formats (raster data, point clouds, coordinate systems).
  • Ability to work independently, structure and document work systematically, and communicate results effectively.

Desired Qualifications

  • Swedish language skills are considered an advantage.
  • Knowledge of, or a strong interest in, remote sensing, image processing, machine learning, and deep learning.
  • 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 thesis project close to the business.
  • Work alongside experienced specialists.
  • Tackle challenges where your ideas and perspectives can make a real difference.
  • Gain experience in data fusion, machine learning, and remote sensing for the energy transition.
