Evaluating the impacts of land use/land cover changes across topography against land surface temperature in Cameron Highlands.

The Cameron Highlands has experienced multiple land encroachment activities and repeated deforestation, leading to extensive land-use and land-cover change (LULCC) during the past six decades. This study aims to determine the LULCC against topography in Cameron Highlands between 2009 and 2019 by usi...
