3D Geoinformation-Based Modelling of Interests on Space Exploration

Abstract. Today, with the rapid development of space technologies, the number of missions and research on celestial bodies is increasing. Space missions to a number of celestial bodies, such as the Moon and Mars, are being planned by countries. In this context, studies and discussions continue on issues such as property rights related to celestial bodies and, in this context, how to use different resources such as minerals and how to regulate the restrictions needed for different purposes such as the space heritage. Today, there is a need for studies that will contribute to the interoperability between applications, researchers and institutions, based on data modelling, in order to establish an international business framework on the subject. In this direction, this study aims to initiate an approach that will allow the creation of three-dimensional (3D) digital models of physical objects and logical spaces in the context of possible interests that may exist on the surface of celestial bodies or underground, by extending the open geodata standard, namely CityJSON in this sense. A CityJSON dataset that encompasses the selected cases containing the craters and locations that cover possibly water on the lunar south pole is created, and then it is visualised in different tools. The initial results are expected to contribute to increasing the efficiency in planning of scientific research missions to celestial bodies and to the establishment of legal frameworks to be developed for the equal utilisation of space resources.
