Macrostrat is a digital model of the Earth's crust: a database that links geologic maps, stratigraphic columns and a shared geologic vocabulary into one framework through space and time. It is developed by the Macrostrat lab at the University of Wisconsin–Madison together with a growing community of geologists and developers, and it underlies the Rockd mobile app and many other applications.
These pages explain what Macrostrat is, how it works, and how to use and contribute to it.
