(CDS) hips_copyright = Universite de Strasbourg/CNRS obs_title = Mercury MESSENGER Global DEM 665m obs_collection = Mercury MESSENGER obs_description = A global digital elevation model (DEM) of Mercury at 665 m/pixel resolution was generated using ISIS3 software and MDIS narrow-angle and wide-angle camera images from the MESSENGER mission. To handle over 176,000 images with diverse viewing conditions, new automated feature-based matching and control techniques were developed, improving tie point accuracy, control point density, and computational efficiency. This second version of the DEM applies a 1-sigma filtering step to the point cloud, refining results compared to the original release. #obs_ack = Acknowledgement mention prov_progenitor = https://astrogeology.usgs.gov/search/map/mercury_messenger_global_dem_665m bib_reference = 2016LPI....47.2959B , 2007SSRv..131..247H and 2001P&SS...49.1445S bib_reference_url = https://doi.org/10.1007/s11214-007-9266-3 obs_copyright = USGS Astrogeology Science Center obs_copyright_url = https://astrogeology.usgs.gov/ #t_min = Start time in MJD ( =(Unixtime/86400)+40587 or https://heasarc.gsfc.nasa.gov/cgi-bin/Tools/xTime/xTime.pl) #t_max = Stop time in MJD #obs_regime = Waveband keyword (Radio Infrared Optical UV X-ray Gamma-ray) #em_min = Start in spectral coordinates in meters ( =2.998E8/freq in Hz, or =1.2398841929E-12*energy in MeV ) #em_max = Stop in spectral coordinates in meters hips_builder = Aladin/HipsGen v12.135 hips_version = 1.4 hips_release_date = 2025-09-22T08:59Z hips_frame = mercury hips_body = mercury client_category = Solar system/Earth/Mercury hips_order = 3 hips_order_min = 0 hips_tile_width = 512 #hips_service_url = ex: http://yourHipsServer/Mercury DEM-665m hips_status = public master clonableOnce hips_tile_format = jpeg fits hips_pixel_cut = -6000 6000 hips_initial_ra = 0.0 hips_initial_dec = 0.0 hips_initial_fov = 180.0 hips_pixel_scale = 0.01431 s_pixel_scale = 0.01562 dataproduct_type = image moc_sky_fraction = 1 hipsgen_date = 2025-09-22T08:51Z hipsgen_params = in=data/DEM-665m out=hips/CDS_P_Mercury_DEM-665m id=CDS/P/Mercury/DEM-665m tiles hips_creation_date = 2025-09-22T08:51Z hipsgen_date_1 = 2025-09-22T08:59Z hipsgen_params_1 = in=data/DEM-665m out=hips/CDS_P_Mercury_DEM-665m id=CDS/P/Mercury/DEM-665m "pixelCut=-6000, 6000" JPEG hips_license = ODbL-1.0 hips_bunit = m hips_pixel_bitpix = 16 data_pixel_bitpix = 16 hips_sampling = bilinear hips_overlay = overlayMean mergeOverwriteTile treeMean
