Norgeskart has recently published a variety of on-line great mapping services for PC as well as for Android and
Iphone based units. See screenshot from my Galaxy 10.1 Tab below.
In addittion to nautical
charts,you can have a combination of detailed topo
charts in colour or b&w,even with optional sea
depth information.
You can select the charts in full
screen mode with no disturbing ads or other unwanted objects. The cross-icon in the centre of the
screen displays the geographical position in decimal degrees down in the bottom left corner.
Although you are not meant to,it is easy to copy and convert to a living .kap format sea chart using MapCal II and GE2KAP.
Again,another POI link I certainly will include in my
Norway POI group in
OpenCPN for quick access to detailed info.Something I have already done with GeoGarage as you can read about in the OCPN section
