| dc.description.abstract | Urban expansion, defined as the increase in the built-up area of settlements accompanied
by population growth, has a long history influenced by human activities. However, in
densely populated areas, urban growth can occur without physical expansion, while urban
expansion can occur without substantial population growth due to densification. The
developing world has experienced rapid growth across various industries, with tourism
emerging as a significant and expanding global sector. Unplanned urban expansion
has led to the issue of urban sprawl, which has become a prominent topic in various
scientific disciplines. This study focuses on investigating the expansion of Mirissa Tourism
City. The primary objective is to determine urban land expansion using Shannon’s
Entropy value. Remote sensing and Geographic Information Science (GIS) techniques
offer methods to assess expansion indices using satellite imagery. Satellite images from
2005, 2010, 2015, and 2020, obtained from United States Geological Survey (USGS)
Earth Explorer, and were used as primary data sources. The Normalized Difference
Built-up Index (NDBI) was employed to extract the built-up areas and calculate urban
expansion/urban sprawl, enabling the identification of expansion patterns in the study
area. The findings include the generation of maps depicting the expansion of built-up
areas in Mirissa Tourism City, revealing the urban expansion using Shannon’s entropy
value. Incorporating such analysis into town planning allows for the identification of
extension patterns that promote sustainable development. The results indicate that the
region experienced a slight expansion between 2005 and 2010, followed by a moderate
rate of expansion from 2010 to 2015 and in 2020. Ultimately, the output highlights that
urban expansion predominantly occurred from the beach-side towards the city center
area in Mirissa Tourism City. | en_US |
