Recent work on PCDB Waypoints has concentrated on getting it to generate KML ("Keyhole Markup Language") files that can be read by Google Earth. This is now reasonably successful, at least in the PC version. I've used it to generate files of the various voyages I've been on over the last 60-odd years, some in my own boat, some on troop ships when my father was in the army after the Second World War, and others in cruises that Elaine and I have enjoyed over the last few years. Getting it to work wasn't particulary easy, as the documentation is a bit difficult to follow, but I can now follow the routes of each of the voyages I've recorded. I still need to complete the sework on the Icons used to show the type of waypoint; that's easy but tedious.
The Android version of PCDB Waypoints is coming on apace, but doesn't support this feature yet. However, I can copy KML files generated on the PC onto my tablet, and with the help of a useful app called "KML to Earth", show a voyage on the tablet's version of Google Earth (I'm running version 7.0). I won't be taking my PC to Northern Ireland, but the Irish routes are now fully planned out and I can display them all on Google Earth.
Now if I could overlay this data on my Android Navionics app...
