Recent asteroid missions including Hayabusa, Hayabusa2, and OSIRIS-REx, have obtained various datasets of asteroidal surfaces, which are of great value for scientific analyses and future explorations (e.g., Lucy, DESTINY+, etc.). For increasing the availability and applicability of these data, it is important to develop a user-friendly system in which image data, metadata, and individual information (e.g., image position) are linked to each other. It is desirable to develop a system that allows users to easily browse and search data according to their own requirements.
There are several two-/three-dimensional (2D/3D) visualization interfaces (both in application softwares and web-based systems) for viewing and searching datasets: for example, the PILOT (U.S. Geological Survey) [1], Small Body Mapping Tool (Johns Hopkins University) [2], JMARS (Arizona State University) [3], Solar System Trek (NASA) [4], etc. As a data retrieval system for existing small celestial bodies, a 2D-3D switchable display is the most desirable interface, which helps research activities (e.g., researchers can browse and study images overlaid on a 2D map and a 3D shape model similar to the way terrestrial geologists investigate a specific area horizontally and vertically). However, the existing systems for browsing image data of small celestial bodies are limited to either a 2D or 3D display. Therefore, this study aims to develop a web system that can switch between 2D and 3D map displays of small celestial bodies in the same system.
Here we used the ONC image datasets of the asteroid Ryugu as the case study. This is because the Hayabusa2 spacecraft has achieved the acquisition of a vast amount of ONC image data of the asteroid Ryugu, which is the highest level of quality and quantity among all the data explored thus far. Furthermore, the shape of Ryugu is relatively spherical, which is useful to validate the concept of a 2D-3D switchable map. Furthermore, the ONC image datasets are well organized, and all of these data will be publicly available widely, which is useful to demonstrate the system. In this presentation, we report the current status of the system development and its usage.
