The IEGDR is released in two formats, an ASCII table and an image. The table (this data set) has one row for each latitude-longitude bin, from 90 to -90 degrees latitude and from 0 to 360 degrees longitude. Values for planetary radius, areoid, topography, and number of observations per bin are stored as columns in the table.", "identifier": "urn:nasa:pds:context_pds3:data_set:data_set.mgs-m-mola-5-iegdr-l3-v1.0_x452-7qvd", "issued": "2021-05-21", "keyword": ["mars-global-surveyor"], "landingPage": "https://pds.nasa.gov/ds-view/pds/viewDataset.jsp?dsid=MGS-M-MOLA-5-IEGDR-L3-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": "MOLA INITIAL EXPERIMENT GRIDDED DATA RECORD"}
