This dataset includes 3-Color Multispectral Reduced Data Records for the WAC. The 3-Color Map Projected Multispectral RDR (MD3) data set consists of a 3-color map of northern and equatorial latitudes acquired during MESSENGER's Extended Mission, and includes I/F in the 3 filters used for this map. This product has higher spatial resolution than, and complements, an 8-color multispectral map acquired during the primary mission. This product is photometrically normalized to a solar incidence angle (i) = 30 degrees, emission angle (e) = 0 degrees, and phase angle (g) = 30 degrees at a spatial sampling of 128 pixels per degree. The map is divided into 'tiles', each representing the NW, NE, SW, or SE quadrant of one of the 13 non-polar or one of the 2 polar quadrangles or 'Mercury charts' already defined by the USGS. Each tile is composed of 3 bands corresponding to 3 of the 11 WAC filters. Each tile also contains backplanes describing ancillary information. The subset of 3 of 11 available multispectral filters samples both albedo and spectral slope over MDIS's wavelength range. The fewer colors than in the Primary Mission 8-color product is to balance the higher spatial resolution to manage data volume during acquisition.", "identifier": "urn:nasa:pds:context_pds3:data_set:data_set.mess-h-mdis-5-rdr-md3-v1.0_6imd-zh4c", "issued": "2021-05-21", "keyword": ["mercury", "messenger"], "landingPage": "https://pds.nasa.gov/ds-view/pds/viewDataset.jsp?dsid=MESS-H-MDIS-5-RDR-MD3-V1.0", "license": "http://www.usa.gov/publicdomain/label/1.0/", "modified": "2025-07-17", "programCode": ["026:005"], "publisher": {"@type": "org:Organization", "name": "National Aeronautics and Space Administration"}, "references": ["https://pds.nasa.gov"], "theme": ["Earth Science"], "title": "3-COLOR MESSENGER MDIS MAP PROJECTED MULTISPECTRAL RDR V1.0"}
