Chart platform for professionals
Your application displays our charts, we handle the rest. The GeoGarage platform streams chart layers derived from official hydrographic office data to third-party applications — we take care of hosting, updates and consistency across sources, so you can focus on building your product.

A pioneer you can trust
Founded in 1997, the GeoGarage team pioneered nautical webmapping: in 2008 it was the first to offer a continuous online display of the complete NOAA nautical raster chart catalogue — 1,018 charts at the time. Read more on our About page.
