urn:nasa:pds:orex.altimetry:data_derived_altimetry_global_tileset_models 1.0 1.7.0.0 Product_Collection Barnouin, O.; Daly, M.; Espiritu, R.; Lauretta, D.S. Crombie, M.K.; Hammond, D. 2026 This collection contains the global tileset models derived from the OSIRIS-REx Laser Altimeter (OLA) and Stereophotoclinometry (SPC) components. The tilesets are local DTMs that can be stitched together to create a global model. Several versions of the models are given, with models designated SPC generated from Stereophotoclinometry and those designated SPO generated from the combination of OLA and SPC. The model designated SPOv54 is to be used for ongoing scientific analysis. Other models were used at various points during the mission for both operational and publication purposes. The version numbers given here correspond to version numbers given in various OSIRIS-REx scientific publications. USE SPOv54 FOR SCIENTIFIC ANALYSIS Note that in the SPC derived DTM .FITS files, there is an error in the statistics planes. PLANE9 = 'Sigma ' PLANE10 = 'Quality ' SIGMA was supposed to be the standard deviation from the individual SPC maplets that went into making the DTM at that pixel. QUALITY was supposed to simply be the number of images that went into the SPC product at that pixel location. The values in these planes are nonsense, and should not be used. All other planes contain accurate values This IS NOT a problem for OLA (data_derived_lidar_* collections) derived DTM .FITS files, which have good SIGMA and QUALITY planes. 2026-02-17 1.0 Initial delivery of OSIRIS-REx Altimetry global tileset models. 2016-09-08Z Science Derived Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer (OSIRIS-REx) Mission urn:nasa:pds:context:investigation:mission.orex collection_to_investigation OSIRIS-REx Spacecraft Spacecraft The sub-systems that comprise the OSIRIS-REx spacecraft are the telecommunications subsystem; the power sub-system; the propulsion sub-system; and the guidance, navigation, control (GNC) sub-system. These sub-systems work together to communicate with the Earth, deliver the spacecraft to the target asteroid, and navigate around the asteroid. The spacecraft hosts a navigation camera system (TAGCAMS), a science camera system (OCAMS), a visible and infrared spectrometer (OVIRS), a thermal emission spectrometer (OTES), and a laser altimeter (OLA). The collection, retrieval, storage and return of the asteroid sample is conducted using the Touch-And-Go Sample Acquisition System (TAGSAM), and the Sample Return Capsule (SRC). The combined spacecraft sub-systems and the hosted complement of instrumentation allows the OSIRIS-REx mission to gather data, collect a sample, and safely return the sample to Earth. urn:nasa:pds:context:instrument_host:spacecraft.orex is_instrument_host OLA Instrument urn:nasa:pds:context:instrument:ola.orex is_instrument OCAMS Instrument urn:nasa:pds:context:instrument:ocams.orex is_instrument (101955) Bennu 1999 RQ36 Asteroid urn:nasa:pds:context:target:asteroid.101955_bennu collection_to_target urn:nasa:pds:context:resource:resource.orex.altimetry_online has_resource urn:nasa:pds:orex.mission:document:orexmissioninfo collection_to_document urn:nasa:pds:orex.altimetry:document:altimetry_sis collection_to_document urn:nasa:pds:orex.ola:document:olasis70 collection_to_document Data collection_derived_altimetry_global_tileset_models.csv 0 PDS DSV 1 888 Carriage-Return Line-Feed Comma 2 0 Member Status 1 ASCII_String 1 %1s LIDVID_LID 2 ASCII_LIDVID_LID 255 %-255s inventory_has_member_product
