[PPS03-P05] JAXA Asteroid Data Explorer (JADE) for accessing and retrieving asteroid image data
キーワード：Hayabusa2 ONC data、Data retrieval system、Web system
For enhancing the availability and applicability of asteroid image data, it is crucial to develop a user-friendly system in which image data, metadata, and individual information (e.g., image position) are linked. Here, we develop and update a JAXA Asteroid Data Explorer (JADE) web system that can switch between 2D and 3D map displays of asteroids in the same system from the previous report [1].
ONC image datasets of the asteroid Ryugu are used in current JADE. Hayabusa2 spacecraft has acquired 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. The ONC image datasets are well organized, and all of these data will be publicly available widely, which is helpful to demonstrate the system. The ONC of Hayabusa2 provides detailed information on the data acquisition, such as the imaging time, the distance between the imaging position and the spacecraft, and the solar phase angle at the imaging point. A variety of product-level data have been generated [2]. Characteristic topograpy types on the surface of Ryugu have been named with the location of the places. Various maps have been obtained by combining high-resolution images or images with several filters [3-5].
JADE has detailed sorting and filtering functions. It allows users to browse and download the image data they want, arranged according to their preferences. By switching between 2D and 3D maps, users can specify the polygon or latitude and longitude of any point on Ryugu they want to focus on and obtain image data, including that area.
We are especially focusing on improving the user interface, which is directly related to ease of use (Figure 1). We will report the current status of JADE at the conference. The following links (https://jlpeda.jaxa.jp/) will provide the latest information on JADE.
Acknowledgments: We are deeply grateful to JAMSS, Konniesystem, and AstroArts for their excellent cooperation in the development of JADE.
