| dc.description.abstract | Sri Lanka is still a developing country. Therefore, various changes are taking place in
the construction sector, both legally and illegally. Such illegal constructions are common
in developing countries. With the development of the country, the numbers of illegal
settlements are increasing along the coastal zone of Sri Lanka. This process is harmful
to the coastal conservation of the country. Therefore, Coast Conservation Act 1981,
1988, 2011 (Amendment) was implemented by Coast Conservation and Coastal Resource
Management department to protect coastal zone and reduce unauthorized constructions
but there is a problem whether the regulations of the Coast Conservation Act are properly
followed or not at the coastal management zone. So, the main objective of this study was
to identify the infringements in the coastal zone. Locations were selected by the experts
of this field, and they were from Kudawella west to Mawella south and from Unakoratuwa
west to Medaketiya in the Hambanthota district because those areas were the highly
affected locations through the district. To fulfill the main objective of the study, the
proposed methodology was to create normalized difference build-up index maps using
Landsat satellite images and final vegetation line coordinates. As the final result, this
study gained reclassified building index map for the selected locations and this study
depicts the role of remote sensing and geographic information systems to identify the
sustainable development growth of the area. | en_US |
