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

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.

 

Municipality classification by land use patterns

This is an ongoing investigation of the land use patterns of my homeland, Finland.

Finland is a country with a huge variability in the land use patterns within administrative municipalities (cf. LocalFinland.fi for background information). The major towns are packed with infrastructural and residential areas filled with productive economical activities, whereas the administrative burden of the northern municipalities extend over large, practically uninhabitated areas of forests, and only a small portion of the administrative area is affected by economically active infrastructure. kuopio_corine
