How do I get the Maps to show on remote device

[Surfer2010]

Hello,

I have OpenPlotter set up with OpenCPN on my Raspi, once I connect to this network with my smartphone or tablet with OpenCPN installed ... how would I access the maps installed at the Raspi?

I know i could use the VNC Viewer to log onto the Raspi screen, but isn't there a simpler way also to control/navigate with opencpn at the smartphone? Also how do i get the GPS/depth/... sensor data to show on my smartphone?

Thanks in advance
