  • Benthic habitat map for six classes of habitats. The map was generated based on multibeam echosounder datasets acquired with two frequencies: 150 kHz and 400 kHz. Suprevised classification was performed using object-based image analysis and combined k nearest neighbour and random forest results. It allowed reaching 93% of overall accuracy and 0.90 Kappa Index of Agreement. This research was funded by EU BONUS-185 ECOMAP project (Baltic Sea environmental assessments by opto-acoustic remote sensing, mapping, and monitoring) and co-financed by the National Centre for Research and Development no. BONUS-BB/ECOMAP/07/2017.
