Abstract

Indian coastal zones have diverse ecological and geomorphological features; however, they are recurrently influenced by anthropogenic activities and natural disturbances. Therefore, understanding coastal land use and land cover features is essential for protecting these zones. Remote sensing is a crucial tool for identifying and quantifying coastal features with synoptic coverage. The present study focuses on land use and land cover mapping along the Tirunelveli coast using QGIS and LISS III datasets. The results revealed the following land cover classifications in the Tirunelveli coastal area: barren land (17.083 km²), built-up area (26.096 km²), dense vegetation (24.167 km²), industrial discharge (3.186 km²), industrial waste (1.716 km²), low-density vegetation (36.818 km²), sand dune plants (18.568 km²), sandy beach area (32.710 km²), scrub area (14.426 km²), Teri sand area (20.553 km²), and water bodies (including freshwater and seawater), covering 305.068 km². The overall classification accuracy was 86.85%. This study provides valuable insights into the coastal regulation zone in the Tirunelveli coastal area and may contribute to future coastal conservation research.
