| 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 number of illegal
settlements is increased 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 with
whether the regulations of the Coast Conservation Act is
properly followed or not at the coastal management zone.
So, the main objective of this study was to identify
infringements in the coastal zone. Locations were selected
for this study by experies of this field and they were from
Kudawella west to Mawella south and from Unakoratuwa
west to Medaketiya in the Hambanthota district because
that areas were the highly affected locations through the
district. To fulfill that main objective of study, the proposed
methodology was to create normalized difference build-up
index maps using Landsat satellite images and final
vegetation line coordinates. As final result, this study
gained reclassified building index map for selected
locations and this study depicts the role of remote sensing
and geographic information systems to identify the
sustainable development growth of an area. | en_US |
