These are useful for example hiking. Not the prettiest to look at, but have a lot of detail. Compare the example below to the google maps link of the same location.
Example:

Same in Google Maps:

I would also like to see these maps. They are very good Finnish topo maps. Currently there are no other program supporting those.
