Abstract: Urban expansion, particularly in the global south, has brought numerous environmental consequences which require regular investigation. The current study assessed the growth of built-up areas in the Chbar Ampov district (Phnom Penh, Cambodia) using the Indices-Based Built-Up Index (IBI) derived from Landsat 8 satellite imagery. We applied the IBI method to satellite images from 2013 to 2021 to determine changes in the built-up area over time and their correlation with land surface temperature (LST). The research revealed generally consistent urban expansion (1.68 square kilometres per year) in the study area within the period. Despite minor inconsistencies due to temporary land-use changes and cloud interference, the results support the study's major conclusions. The findings reinforce the necessity of meticulous monitoring and management of urban expansion. Dynamic analysis and practical research methods can contribute to sustainable urban development practices, thus ensuring a balance between human progress and environmental preservation. Keywords: urban expansion, built-up area, change detection, remote sensing Published Online: 2023/12/18 06:16:43 Object Identifier: 0xc1aa5576 0x003eafee Rights:https://creativecommons.org/licenses/by-nd/4.0/ “GI_Forum” publishes high quality original research across the transdisciplinary field of Geographic Information Science (GIScience). The journal provides a platform for dialogue among GI-Scientists and educators, technologists and critical thinkers in an ongoing effort to advance the field and ultimately contribute to the creation of an informed GISociety. Submissions concentrate on innovation in education, science, methodology and technologies in the spatial domain. “GI_Forum” implements the policy of open access publication (CC-BY-ND-License) after a double-blind peer review process through a highly international team of established scientists for quality assurance. Special emphasis is put on actively supporting young scientists through formative reviews of their submissions.
