Cockpit should store map tiles so users that boot offline can use the map features
My preferred approach for this is for it to be handled in BlueOS / a separate extension/add-on (per bluerobotics/BlueOS#1820), so extensions don't each need to download their own map data.
If that's managed well the maps service could handle relevant online APIs for downloading from different mapping sources, and any extension could use the service's local API to request whatever map area + source it wants.
An associated add-on could provide a link to the folder where the current maps data is stored for any extensions that want it, so they only need to request data if what they want isn't already there, and if they support adding custom maps/overlays then they can add them to the folder directly to allow other extensions to make use of them if they want to.
this ins interesting. paid for commercial use, but interesting

I don't think we should rely on BlueOS for such a critical feature on the long term (although I'm not against someone implementing it over there for an initial version).
Yeah I'm actually thinking of how to handle user-generated tile data. Like drone shots, photogrammetry stuff, sonar mosaics, and so on. For smaller areas we could just use cesium's single tile entry with the full thing, but I feel like that wouldnt scale

+1 for a layered and user customisable approach to this. The basics of maps being available without internet connection a must, even for coastal operations. For benthic photogrammetry it would be extra cool to be able to add geolocated thumbnails of the stills images being taken, as they're being taken. So, not photogrammetric stitching on the fly, just images on a layer with correct position, orientation, scale. That would help you drive around and navigate areas for photogrammetry.
@pkmiles cool idea! we could get the camera fov and scale the image size based on rangefinder+rov depth, too.
