Macrostrat is the world's largest homogenized geologic map database, with over 225 maps from data providers around the world at every scale. Our data processing pipeline links geologic map polygons to stratigraphic columns, geologic name lexicons, and geochronological intervals. This enhancement of map data allows for direct links to the literature via xDD.

Macrostrat's stratigraphic columns account for the organization of rocks in the crust and their evolution over Earth history.
Macrostrat stores both regional columns that represent a unified chronostratigraphic framework and measured sections and drill core logs that provide detailed information about specific locations.
