Abstract (EN):
The aim of this work is to identify morphological and hydrodynamic patterns (e.g. coastal forms, wave breaking zones, rip currents patterns, submerged bars), based on several aerial images. Understanding the patterns, which occurred in the past, may help to increase the knowledge to predict future ones.
To accomplish this, a GIS database, an analysis algorithm and a user-friendly GIS tool are currently under development. The GIS database will enable to store all available image survey sets, as well as to store the results of the performed visual and computed analysis. This former analysis consists in a Matlab 7.0 algorithm, which uses mainly the toolbox image processing. For non GIS specialists, a specific tool to visualize, overlap and search is being developed using Visual Basic 6.0, and MapObjects 2.3.
