[PPS06-P03] QGIS Plugin for Browsing of Multiband Imager Data from SELENE Lunar Probe
キーワード：Lunar, GIS, Multiband Imager
The Multiband Imager(MI) of the SELENE Lunar Probe was part of the Lunar Imager/Spectrometer (LISM) of the SELENE Lunar Probe. It collected data via usage of visible and near infrared sensors, whose data covers 9 spectral bands [1]. The data gives information about mineral distribution on the lunar surface, allowing for derivation of mineral maps. The derived data is available publicly via the SELENE Data Archive, provided by the Japan Aerospace Exploration Agency (JAXA)[2]. The data can be viewed using various GIS software.
QGIS is a free, open source, cross-platform GIS application which allows viewing, editing and analysing geospatial data[3]. It also contains support for plugins via the Python programming language. While there are many freely available plugins, additional functionality is desired in order to easily browse and annotate MI MAP data. Thus, we developed a QGIS plugin designed specifically for MI MAP data. Current functionality allows for saving selected coordinates with associated band data and annotations in the csv format, loading coordinates and annotations from the csv format, displaying and saving spectral graphs and programmatically marking selected coordinates on the visual map.
While some of the plugin tools are available in other GIS tools, or as other plugins in QGIS, the tools either require monetary payments or offer insufficient functionality. The plugin is designed to be user-friendly, and uses tools built into QGIS in order to avoid dependency issues. The Object Oriented approach of the design also allows it to be easily modified to be used with other types of data.
