I was using Google
Earth the other day and ran across someone using EveryTrail
Its a web service
that creates a path that automatically gives the viewer a "Tour" of each key location with pictures and comments. The only problem is that the trip itself is linked to their proprietary website. I also think that it uses the GPS
location of pictures other than just KML. I could be wrong though, you might be able to upload your GPS
information and create the tour interactively. I kind of caught that you can embed their map on your blog if you sign up, so thats a plus.
I don't know how fluent you are in programming or KML, but there are also a ton a ways you can do it actively while sailing too.
What I did for my blog is export my GPS information as KML then use a plugin for wordpress that translates that file into a Google
Maps journey on my webpage. The plugin looks for a KML desginated file each time the page is loaded then displays that trip. So I just upload the file using ftp. You can also make a POST in wordpress with the KML information and it will update that way too. So if you can send email
you can update the map using Wordpress's remote email posting
Most Navigation software
these days on a laptop
can export your paths directly as KML as well, so its just a matter of getting that to your webserver / blog for it to work.
If you goto Wordpress's official site, you can search for KML in the plugins section and find a couple that might meet your needs. Personally I am unhappy with a lot of the features so have been toying with a Google Maps / Earth script that will incorporate pictures with the paths as well.
This is the plugin I have been using as of date: XML Google Maps Plugin
Check out the "Samples" section to get an idea of the end product.
If you need any help tinkering with settings etc. Send me an IM and I'd be glad to help out.
