For the last three months I have been on a backpacking trip, which is part of the reason why this blog has been so neglected for the past few months. A travel blog hosted at meandmypack.wordpress.com had taken precedence, and I habitually kept that one updated throughout my trip. With all of that over though, I’ve had to find things to do in my time to keep my self from becoming bored and lethargic with life back home in Canada. One such activity is the tying up of loose ends as far as documentation of my trip is concerned, and from early on I had it in my mind to make a nice map of all the places I went. Over time this idea evolved into a whole project in it’s own right, using Google maps and becoming more interactive and feature rich every time my mind drifted back to the idea of it. I couldn’t really spare the time to design it while in Europe, and that probably would have been a waste of the limited time I had there any way. So I stored the idea away and made a promise to my self to figure it out back home. Now some two weeks later, I’ve pulled it off.

To start, I began with the Google Maps API v3 Simple Polylines example code and then added in this code for adding in markers to the map. The poly line consists of a large number of latitude and longitude coordinates that I fetched from Google maps using the LatLng Marker plugin available through Google Maps Labs. With a stubbornness that could be mistaken for OCD, I made sure the PolyLine at least vaguely resembled my true route between major destinations by routing them through all of the intermediate stations that the train called at along the way. This was accomplished with the travel report from my Eurail Pass ( I knew I diligently filled it out for a reason), and the Eurail timetables. With these two tools, I could easily go back and find the true route of most of the train travel I did during my trip. Elsewhere when I didn’t travel by train I figured the route out through some combination of memory and Google. The markers for all of the main cities and attractions that I visited were simply made by selectively harvesting those coordinates from the Polyline list and then adding them to their own modified list with extra fields for the associated tag on my blog, and the blurb for the popup info box. I modified the marker code to put a link to the associated content on meandmypack.wordpress.com inside that popup box.  Finally I felt that it would be nice to calculate the distance travelled from the Polyline, which I did with the help of this code.

With all of the main features of the map coded, and a few hours spent finding the geospatial coordinates of my route, I had a decent looking finished product. I spent just a little more time on the layout and design of the page so that some information about the map was presented in a permanent box in the top left hand corner. I’ve also decided to post the final draft of the code below for easy viewing by all interested parties:
