Can you add support for downloading the marine charts layer for offline use? Being a NOAA chart I don't believe there are license issues.

Thank You,

    Hi Jess,

    We don't have marine charts available as a layer right now at all, online or offline. Do you have them pulled in as a custom layer maybe? If so I'd love to see the source.

    In the way we currently have things set up, even if we were to add marine charts as a layer, unless we get loads of requests to have them offline, we probably won't host them for that. We might, possibly, one day in the distant future, change our system around to make such a thing possible for you. Apologies are all I have to offer right now though.

    In the Caltopo app under Base Layers then Other Maps there are Marine
    Charts. They appear to be the standard free NOAA raster charts. They work
    great especially overlaid with satellite images I just need to be able to
    use them offline.

    Thank You,

    Hi Jess,
    We don't have permission to use that source offline. CalTopo did not create that tileset. While the data tiled in that layer is public domain, creating a tileset like that is material modification and therefore they are subject to copyright concerns. Sorry!
