Geocachers view of the Southern Finland

This is how the Southern Finland looks like to a geocacher.

Adventures

Below is a time-lapse video of all hidden caches. Each dot is a hidden cache, red dots are new caches each day. Lots of adventures available, though this might not say much to non Finns. You may want to switch to a full screen view to see the details.

Augmented historical maps

There is a set of old city maps of Turku (Finland) at Kapsi. As a resident, those maps are interesting in their own right, but when they are georeferenced, a whole new world of opportunities open up.

So I opened up QuantumGIS and georeferenced the maps of Turku from 1888 and 1950, and overlayed the current transportation network on the hand-drawn maps from the past. It’s nice to notice that the old main transportation pathways (bridges, roads to other cities) and landmarks are still in place and in everyday use!

Train travel delays in Finland

VR Group is currently the only company providing passenger train services in Finland, with less than optimal success in timeliness. Some time ago VR released a service for tracking train status and location in real-time. The service also informs how much each train is delayed.

The founder of Junainfo, Mikko Jokinen, provided me with a chunk of archived data from Jan-Feb 2015. The data has wealth of potential for analysis, but for a quick look here is an animation that illustrates the pulse of trains that VR has tracked for some weeks in January 2015.
