Alos PRISM L1B

This collection provides access to the ALOS-1 PRISM (Panchromatic Remote-sensing Instrument for Stereo Mapping) L1B data acquired by ESA stations in the ADEN zone plus some data requested by European scientists over their areas of interest around the world. The ADEN zone (https://earth.esa.int/eogateway/documents/20142/37627/ALOS-ADEN-Zone.pdf) was the area belonging to the European Data node and covered both the European and African continents, a large part of Greenland and the Middle East.

The full mission is covered, though with gaps outside of the ADEN zone:

Time window: from 2006-07-09 to 2011-03-31
Orbits: from 2425 to 24189
Path (corresponds to JAXA track number): from 1 to 668
Row (corresponds to JAXA scene centre frame number): from 55 to 7185.
Two different Level 1B product types (Panchromatic images in VIS-NIR bands, 2.5 m resolution at nadir) are offered, one for each available sensor mode:

PSM_OB1_11 -> composed of up to three views; Nadir, Forward and Backward at 35 km swath
PSM_OB2_11 -> composed of up to two views; Nadir view at 70 km width and Backward view at 35 km width.
All ALOS PRISM EO-SIP products have, at least, the Nadir view which is used for the frame number identification. All views are packaged together; each view, in CEOS format, is stored in a directory named according to the view ID according to the JAXA naming convention.

本数据集提供了由欧洲空间局站点在ADEN区域获取的ALOS-1 PRISM（用于立体测图的彩色遥感仪器）L1B数据的访问权限，以及欧洲科学家在其全球范围内感兴趣区域请求的一些数据。ADEN区域（https://earth.esa.int/eogateway/documents/20142/37627/ALOS-ADEN-Zone.pdf）隶属于欧洲数据节点，涵盖了欧洲和非洲大陆、大部分格陵兰岛以及中东地区。整个任务均被覆盖，但ADEN区域外存在数据缺失：

时间窗口：自2006年7月9日至2011年3月31日
轨道：自2425号至24189号
路径（对应于JAXA轨迹编号）：自1号至668号
行（对应于JAXA场景中心帧编号）：自55号至7185号。
提供两种不同的L1B产品类型（VIS-NIR波段的彩色图像，视场中心分辨率2.5米），每种传感器模式对应一种：
PSM_OB1_11 -> 由最多三个视角组成；视场中心、前视和后视，覆盖35公里视场宽度
PSM_OB2_11 -> 由最多两个视角组成；视场中心视角覆盖70公里宽度，后视视角覆盖35公里宽度。
所有ALOS PRISM地球观测系统图像产品均至少包含视场中心视角，该视角用于帧编号识别。所有视角均打包在一起；每个视角均以CEOS格式存储，并按照JAXA命名规范以视角ID命名的目录中存储。
