Regions share common characteristics and have the ability to influence each other. Surakarta, Karanganyar, and Magetan City, possess tourist attractions that are interconnected and have a mutual influence. The rapid growth and changes in land use along the border of Karanganyar and Magetan especially, align with the development of these tourist attractions, making it essential to study the sustainability of this regional development. Tourism in natural landscapes is influenced by both built capital, such as infrastructure, and natural capital, such as mountains or protected areas. This study aims to assess the sustainability of regional development by analyzing the ecological and built environment typology. The research will identify the spatial typology of tourist attractions in the study area and utilize satellite imagery data to examine the characteristics of tourism corridors. Kernel density analysis used to identify the built environment density over the ecological environment and tourist attractions. The results of the study indicate that tourist attractions and the built environment that supports them have the potential to threaten the sustainability of regional development because they are located in protected forest areas. The findings of this typology will contribute to the sustainable development of tourism in the Surakarta-Karanganyar-Magetan corridor, focusing on the interventions that need to be carried out by relevant stakeholders.
