| Summary: | This paper presents a methodology exclusively based on using the Open Source GIS Technology for the morphometric analysis of the fluvial islets along the Danube course. The study area corresponds to the Giurgiu-Oltenita sector, one of the sectors displaying a relative stability regarding the number and distribution of such geomorphological landforms. In order to identify and achieve a morphometric analysis of the Danubian fluvial islets, we
suggest a set of eight parameters: the total number of fluvial islets, maximum length, maximum width, elongation ratio, area, perimeter, perimeter/area ratio and shape index. The necessary geospatial data used to compute the morphometric parameters have been obtained from cartographic documents and ortorectificated aerial imagery, while in order to obtain the final results, a graphical geoprocessing model has been created and run. |
