The spring is coming to Finland and meltwater is running through rivers into the Baltic Sea. The exceptionally cloudfree Landsat 8 imagery from 2016-04-14 shows beautiful features in the Gulf of Bothnia near the Finnish coastline. Some remaining ice cover still exists at the Bothnian Bay, but algae has already begun to form at the Archipelago Sea.
Below is a zoomable natural color composite of the Landsat 8-imagery in 30 m resolution:
This is how the Southern Finland looks like to a geocacher.
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.
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!
The website Suomen Vesiputoukset has compiled all major waterfalls in Finland into a neat catalog and provide a KML-database as well. The number of waterfalls is rather restricted, so it would make a nice roadtrip for the summer holiday to go and visit some.
You can browse the collection via the map below.
The waterfalls are mostly small, but luckily some of them are easy to access:
