KPLO ShadowCam Derived Data

ShadowCam observations have been processed into a set of derived products, including mosaics, digital terrain models (DTMs), and observation footprints in GeoCSV. These products complement high-resolution data products from the Lunar Reconnaissance Orbiter Camera (LROC) Narrow Angle Camera (NAC) and will provide a foundational dataset for future exploration.

ShadowCam Derived Data Products:

Type	Description	PDS4 Bundle / Collection
CMOS	This controlled mosaic is composed of ShadowCam images typically acquired on sequential orbits, either on a single day or across a short range of days. The images are calibrated and map-projected using spacecraft position data. In these images, shadowed areas are visible if lit by light reflected from nearby surroundings, while sunlit areas are saturated. A control network is generated to tie the images to the most accurate ground truth available and a bundle adjustment is performed to minimize pointing errors and improve image alignment. The images are then map-projected and mosaicked together into an almost seamless mosaic of the region. . See the 'readme' file in each subfolder under the 'cmosaic' directory for more information. Additional information is available below. Product Archive Software Interface Specification (SIS)	urn:nasa:pds:kplo-shadowcam:derived-cmosaic
DTM	High-resolution DTMs (Digital Terrain Models) are generated from stereo image pairs captured by ShadowCam. These models include confidence maps and color-shaded relief maps, providing detailed topographic information essential for understanding the lunar surface's morphology. Product Archive Software Interface Specification (SIS)	urn:nasa:pds:kplo-shadowcam:derived-dtm
UMOS	High-resolution UMOS (Uncontrolled Mosaic) is composed of ShadowCam images typically acquired on sequential orbits, either on a single day or across a short range of days. Using spacecraft positioning data, the images are calibrated and map-projected to the best available LOLA LDEM at a pixel scale of at least 30 m/px or better. If this is not possible, the images are map-projected to the SLDEM2015. The absolute positional accuracy of these images is estimated to be within 60 m. See the 'readme' file in each subfolder under the 'umosaic' directory for more information.Additional information is available below.
