Gaia GPS users can now use official NOAA raster charts in the app. You can add this source by going to “Add More Layers…” in the layers menu. You can also browse the charts online.
We developed this seamless NOAA chart server for use in our app Skipper, which is specialized for use on the water. Skipper does things like automatically update the charts and provide ActiveCaptain information about marinas and hazards. But we also think some Gaia users will find these charts useful, for activities that span land and sea, and we’re happy to provide the source within Gaia too.
