Spatial distribution of optimal astronomical observatories development in Indonesia

Astronomical observatory construction plays an essential role in astronomy research, education, and tourism development worldwide. This study develops siting distribution scenarios for astronomical observatory locations in Indonesia using a suitability analysis by integrating the physical and atmospheric observatory suitability indexes, machine learning models, and long-term climate models. . The provided dataset presents a bivariate analysis showcasing the comparative outcomes between the multi-machine learning approach and the multi-criteria analysis, culminating in the formulation of the Indonesia Astronomy Observatory Suitability Index.
