SAGA GIS for information extraction on presence and conditions of vegetation of northern coast of Iceland based on the Landsat TM
International audience The paper aims to evaluate the presence and condition of vegetation by SAGA GIS. The study area covers northern coasts of Iceland including two fjords, the Eyjafjörður and the Skagafjörður, prosperous agricultural regions. The vegetation coverage in Iceland experience the impa...
