The PostGIS 3.0 release includes over 8000 projections out-of-the-box, including the popular Equal Earth Projection. The Equal Earth Projection is gaining popularity due to its ability to maintain accurate area without distortion. CARTO users can now access and use this projection in their maps, with the option to add it manually or have all 8000 projections automatically added in a future update. Users can apply the projection by copying and pasting a specific SQL definition into the spatial reference table, and then start using it with SRID 8857. Additional projection options are also available, including EPSG 8858 and EPSG 8859 for different regions, allowing users to customize their maps further.
