What is the map projection called in that map from NASA?
- tantalor 5y agoIt basically looks like equirectangular and modified with pointy poles. https://en.wikipedia.org/wiki/Equirectangular_projection https://en.wikipedia.org/wiki/Equirectangular_projection Maybe it is just regular equirectangular but the lines are drawn weird.
- DiogenesKynikos 5y agoIt's a completely standard Cartesian projection (x = longitude, y = latitude), but with nonsense graticules plotted on top. I think BBC took a NASA image of Mars and added their own graticules and landing-site labels. Compare the BBC image with these two NASA images: * BBC: https://ichef.bbci.co.uk/news/976/cpsprodpb/825B/production/_118517333_mars_map_missions_640_2x_v2-nc.png https://ichef.bbci.co.uk/news/976/cpsprodpb/825B/production/... * NASA base map of Mars: https://astrobiology.nasa.gov/uploads/filer_public_thumbnails/filer_public/9e/62/9e629da7-90e2-48f8-a0e4-f573b3e107ff/exomars_landing_sites_in_context.jpg__1240x510_q85_crop_subject_location-620%2C254_subsampling-2.jpg https://astrobiology.nasa.gov/uploads/filer_public_thumbnail... * NASA landing sites: https://mars.nasa.gov/resources/24729/map-of-nasas-mars-landing-sites/?site=msl https://mars.nasa.gov/resources/24729/map-of-nasas-mars-land...
- OmicronCeti 5y agoIt looks like the equirectangular Mars projection. Details can be found on the HiRISE or THEMIS sites.
