How the Safe Passage idea became a proposal, and the breakthroughs that the team made that will soon create this unique service.

The Safe Passage idea becomes a proposal

With an idea and a team in place from the University of Strathclyde with expertise covering space mission analysis, automation, satellite applications, radar and oceanography, the new Safe Passage team got to work researching how satellite data could be used to improve the safety of estuary channels around the world. 

In their work, the University of Strathclyde team were aided by the insight provided by Creative Help’s Gwilym Gibbons and the practical experience and case study of Nith Inshore Rescue.

The research undertaken by the team culminated in a paper, entitled Mapping of shifting tidal estuaries to support Inshore Rescue, which was published in 2020.

The breakthroughs that will create Safe Passage

The team had several breakthroughs, which are shown in their research paper. 

  • The team found that satellite imagery can provide regular, frequent and high-resolution aerial observations. Satellite imagery is therefore an ideal source of information for mapping both land and water features.
  • The team developed an automatic channel mapping service using Sentinel-1 synthetic aperture radar (SAR) data, fused with Sentinel-2 visual data. This is planned to form a new service, Safe Passage, which will maintain an up-to-date map of estuary channels world-wide and provides a Red-Amber-Green change alert system
  • The service will use a wholly new method of change detection that automatically identifies changes in channel location from satellite imagery. 
  • Safe Passage will not only detect the presence of significant changes but also provides clarity on how the river channels have shifted.

Our future
