Ghana – Lake Volta

In collaboration with the Danish Maritime Authority and Ghana’s maritime authorities, the Danish Geodata Agency is engaged in a project aimed at enhancing navigational safety on Lake Volta in Ghana — the largest artificial reservoir in the world by surface area. By leveraging a combination of satellite-based identification and crowdsourced data collection, the Danish Geodata Agency is evaluating hazard zones in pilot areas on Lake Volta.

Project summary

GST’s activities primarily include the following:

  • Crowdsourced Data Collection – Development and testing of methods to collect data from vessels. This is a highly effective method since vessels already routinely operate on Lake Volta. The methods are initially tested in Danish waters, after which data is collected from vessels on Lake Volta for a longer period.
  • Satellite-Based Identification of Hazards – In pilot areas on Lake Volta, satellite technologies and geospatial analyses are used to identify areas and trees that may pose a hazard to navigation on the lake.

The data and results obtained provide end users with crucial information about navigational risks and support capacity building. Furthermore, the results enable the Danish Geodata Agency to better understand the benefits and limitations of crowdsourced data collection and satellite technologies.

The project is part of a broader maritime sector cooperation between Denmark and Ghana – “Maritime Strategic Sector Cooperation between Denmark and Ghana – Phase 3”, running from 1 May 2022 to 30 June 2025.
