Open WL Archief (OWA)

Over het archief

Het OWA, het open archief van het Waterbouwkundig Laboratorium heeft tot doel alle vrij toegankelijke onderzoeksresultaten van dit instituut in digitale vorm aan te bieden. Op die manier wil het de zichtbaarheid, verspreiding en gebruik van deze onderzoeksresultaten, alsook de wetenschappelijke communicatie maximaal bevorderen.

Dit archief wordt uitgebouwd en beheerd volgens de principes van de Open Access Movement, en het daaruit ontstane Open Archives Initiative.

Abstract

The Marine Strategy Framework Directive (MSFD, 2008/56/EC) is focused on protection, preservation and restoration of the marine environment by achieving and maintaining Good Environmental Status (GES) by 2020. Within this context, this paper presents a methodological approach for a fast and repeatable monitoring that allows quantitative assessment of seabed abrasion pressure due to recreational boat anchoring.The methodology consists of two steps: a semi-automatic procedure based on an algorithm for the ship detection in SAR imagery and a statistical model to obtain maps of spatial and temporal distribution density of anchored boats.Ship detection processing has been performed on 36 ASAR VV-pol images of Liguria test site, for the three years 2008, 2009 and 2010. Starting from the pointwise distribution layer produced by ship detection in imagery, boats points have been subdivided into 4 areas where a constant distribution density has been assumed for the entire period 2008–2010.In the future, this methodology will be applied also to higher resolution data of Sentinel-1 mission, specifically designed for the operational needs of the European Programme Copernicus.
