45RUM 瓦片的实际产品足迹包含影像目视源区点 28.2877°N, 85.52723°E；不能据此认定源区像素无云或适合量测。The actual product footprint of tile 45RUM contains the visually interpreted source point at 28.2877°N, 85.52723°E; this does not establish cloud-free or measurable source pixels.
原始 JPEG 快视图仅为 343×343，未裁切、未配准、未制作三维瓦片。4.71% 是瓦片云量；产品另有 42.225617% 无数据。快视图左侧黑色为无数据，不能解释为灾损或地形变化；标称 10 m GSD 不是此快视图的分辨率，不能用它测量源区、水体或位移。The original JPEG quicklook is only 343×343, without cropping, registration or new map tiles. 4.71% is tile-wide cloud cover; the product also reports 42.225617% nodata. The black area on the left is nodata, not damage or terrain change. The nominal 10 m GSD is not this preview’s resolution; it cannot measure the source, water bodies or displacement.

足迹包含影像目视源区点 28.2877°N, 85.52723°E；不包含本站吉隆口岸地点，不能作为口岸复照。Footprint contains the visually interpreted source point at 28.2877°N, 85.52723°E; it excludes this site's Gyirong Port location and is not a port follow-up image.
官方整景缩略图原样展示，未裁切、未配准、未制作三维瓦片。整景 8% 云量不能证明源区像素无云；0.66 m GSD 与 0.5 m 输出像元均不是此缩略图的分辨率。不据此认定新的灾损、地形变化或水体面积。Official whole-scene thumbnail displayed unaltered, without cropping, registration or new map tiles. 8% scene-wide cloud does not establish cloud-free source pixels; neither the 0.66 m GSD nor the 0.5 m output pixel size is this thumbnail’s resolution. No new damage, terrain-change or water-area finding is drawn.

足迹包含影像目视源区点 28.2877°N, 85.52723°E；南北狭长条带，不作为河谷全景。Footprint contains the visually interpreted source point at 28.2877°N, 85.52723°E; a narrow north–south strip, not a panorama of the valley.
官方整景缩略图，云与山体阴影明显，未裁切、未配准、未制作三维瓦片。整景 17% 云量不表示源区有 83% 可见；不据此测量灾损或水体面积。Official whole-scene thumbnail with visible cloud and mountain shadow; not cropped, registered or turned into map tiles. 17% scene-wide cloud does not mean 83% visibility at the source. Not used to measure damage or water-body area.
The 12 October Pelican scene on this page has a verified footprint containing this event’s visually interpreted source point. The catalog also includes 15 October imagery for the separate Budhi Gandaki/Chamar landslide; it is excluded from this event’s sequence. Entries are screened by event, footprint, date and licence. Catalog updates alone do not establish new impacts.
