Earth moves. Continents migrate. Coordinates drift. Seasons shift. Axes wander. Fields flip. MSI-DRIFT defines how position evolves through time — consistently, globally, and predictably. A changelog of Earth — across millennia. We document its tilt, orbit and field so humanity never loses the plot.
MSI-DRIFT-1.0 defines the long-term horizontal motion of Earth’s crust using a unified plate-based model. It allows coordinates to be propagated forward or backward in time without ambiguity.
Tectonic plates move centimeters per year. Over decades, maps, borders, infrastructure, and satellite alignment drift apart.
Traditional maps freeze the Earth in time. Over decades, tectonic motion introduces meter-scale errors between datasets, borders, infrastructure, and satellite systems.
This interactive tool will show how tectonic plates move over time, how reference epochs change coordinates, and how MSI-DRIFT maintains consistency across generations of maps.
MSI-DRIFT integrates directly with MSI-TRF and MSI-TOPO to form a time-aware spatial system suitable for Earth and space.
