gmap - qgis training material: Ingenii Basin (moon)

This dataset part of the Geology and Planetary Mapping Winter School 2022 featuring Ingenii Basin as a study area.<br> Ingenii Basin is located on the lunar farside centred at 33.7°S 163.5°E within the South Pole-Aitken basin. The floor of Ingenii Basin is filled with mare materials with the basin having a diameter of 282 km.<br> We compiled a beginners – intermediate level training package for the area. The package includes the Lunar Reconnaissance Orbiter Camera (LROC) Wide Angle Camera (WAC) global mosaic (Speyerer et al., 2011) as a basemap, the Lunar Orbiter Laser Altimeter (LOLA) and SELenological and Engineering Explorer (SELENE) Kaguya merged lunar digital elevation model (DEM) (Barker et al., 2016) and spectral data in the form of a clementine Ultraviolet/Visible (UVVIS) warped color ratio mosaic (Lucey et al., 2000). The data is cut to the area of interest and a training project is set up for QGIS. The training package is designed as a group exercise with four adjacent tiles covering the entirety of Ingenii basin. For beginners the aim is to create a low scale map of the area where the basin rim is distinguished from the basin floor and mare unit as well as detecting smaller craters that exist in the area. These units should then be put in a stratigraphic relationship based on superposition, degradation state and embayment. For intermediate mappers this task can be extended to include the swirl features and finding potential areas for crater size frequency distribution measurement to determine absolute ages for a more detailed stratigraphy. <br>

本数据集隶属于2022年地质与行星测绘冬季学校，研究区域为英格尼撞击盆地（Ingenii Basin）。
英格尼撞击盆地（Ingenii Basin）位于月球背面，中心点坐标为南纬33.7°、东经163.5°，地处南极-艾特肯盆地（South Pole-Aitken basin）范围内。该盆地直径达282千米，盆底被月海物质充填。
我们针对该研究区域编制了面向入门级至进阶级学习者的培训套件。该套件包含以下数据源：以月球勘测轨道飞行器相机（Lunar Reconnaissance Orbiter Camera, LROC）广角相机（Wide Angle Camera, WAC）全球镶嵌图（Speyerer等，2011）作为底图；月球轨道器激光高度计（Lunar Orbiter Laser Altimeter, LOLA）与月球工程与探测卫星（SELenological and Engineering Explorer, SELENE，俗称辉夜姬（Kaguya））融合的月球数字高程模型（Digital Elevation Model, DEM）（Barker等，2016）；以及以克莱门汀号紫外/可见（Ultraviolet/Visible, UVVIS）波段校正色彩比值镶嵌图形式呈现的光谱数据（Lucey等，2000）。
所有数据均已裁剪至研究区域范围，并针对QGIS软件搭建了配套训练项目。本培训套件采用小组实训的设计形式，使用4块相邻的瓦片覆盖英格尼撞击盆地的全域范围。
针对入门级学习者的训练目标为：绘制该区域的小比例尺地质图，区分盆地环壁、盆底与月海单元，并识别区域内的小型撞击坑。随后需依据叠置关系、退化程度与充填状态，确定各单元的地层序列关系。
而针对进阶级测绘学习者，可将训练任务拓展为：识别月表漩涡特征，并寻找可开展撞击坑尺寸频率分布测量的潜在区域，以测定绝对年龄，进而构建更为精细的地层序列。
