Monitoring the changing position of coastlines using aerial and satellite image data: an example from the eastern coast of Trabzon, Turkey

Abstract

Coastline mapping and coastline change detection are critical issues for safe navigation, coastal resource management, coastal environmental protection, and sustainable coastal development and planning. Changes in the shape of coastline may fundamentally affect the environment of the coastal zone. This may be caused by natural processes and/or human activities. Over the past 30 years, the coastal sites in Turkey have been under an intensive restraint associated with a population press due to the internal and external touristic demand. In addition, urbanization on the filled up areas, settlements, and the highways constructed to overcome the traffic problems and the other applications in the coastal region clearly confirm an intensive restraint. Aerial photos with medium spatial resolution and high resolution satellite imagery are ideal data sources for mapping coastal land use and monitoring their changes for a large area. This study introduces an efficient method to monitor coastline and coastal land use changes using time series aerial photos (1973 and 2002) and satellite imagery (2005) covering the same geographical area. Results show the effectiveness of the use of digital photogrammetry and remote sensing data on monitoring large area of coastal land use status. This study also showed that over 161 ha areas were filled up in the research area and along the coastal land 12.2 ha of coastal erosion is determined for the period of 1973 to 2005. Consequently, monitoring of coastal land use is thus necessary for coastal area planning in order to protecting the coastal areas from climate changes and other coastal processes.

Coastline changes in North Bengkalis Island, Indonesia: satellite imagery analysis and observation

“…Parameter of damage in this research is coastline shell and TSS concentration of coastal waters of Bengkalis Island. These parameters were obtained by remote sensing method-as favorite and efficient method (Siahaya et al, 2015;Zhao et al, 2008;Guariglia et al, 2006;Sesli et al, 2009) -using Landsat data. We also serve direct measurement of the parameters for verifying and comparing with satellite imagery.…”

Developing Superfine Water Index (SWI) for Global Water Cover Mapping Using MODIS Data

“…Digital photogrammetry with aerial and satellite imagery have been widely used for the monitoring of shorelines/coastlines, and detecting their temporal and spatial changes in several locations around the world [1][2][3][4][5][6][7][8][9][10][11][12][13]. Besides the optical imagery based approach, the synthetic aperture radar (SAR) based multi-polarization and multi-incidence data have also been used by many researchers for water monitoring and mapping purposes [14][15][16][17].…”

Application of remote sensing and GIS for detection of long-term mangrove shoreline changes in Mui Ca Mau, Vietnam

“…Remote sensing and geographical information system (GIS) techniques have been used widely to assess changes in coastal shorelines (Chen and Rau, 1998;Ghosh et al, 2001;Lin et al, 2001; Van der Wal et al, 2002;Ali, 2003; Vanderstraete et al, 2006;Genz et al, 2007;Maiti and Bhattacharya, 2009;Sesli et al, 2009;Rebelo et al, 2009;Kuleli, 2010;Kuleli et al, 2011;and Hai-Hoa et al, 2013) and the boundaries of mangrove forests and other habitats over time (Woodroffe, 1995;Solomon et al, 1997;El-Raey et al, 1999;Wilton and Saintilan, 2000;Saintilan and Wilton, 2001;Cohen and Lara, 2003;Dahdouh-Guebas et al, 2004;Fromard et al, 2004;Souza Filho et al, 2006;Gilman et al, 2007;Satyanarayana et al, 2011;Giri et al, 2011;Heumann, 2011;and Nfotabong-Atheull et al, 2013). The Digital Shoreline Analysis System (DSAS) is an extension to ArcMap and was introduced to automatically or manually generate measurements of transects and metadata based on user-specified parameters, calculating rates of shoreline (2013) changes and to provide other statistical information (Thieler et al, 2009).…”
