There are quite a few datapoints on top of Finland. As a first step to visualize the data in a relevant way, a weighted location heatmap layer could be used to draw attention to most interesting areas. This should only be available when all activities selected use the same metric: e.g. length or verticality or grade. In the case of caving, this would highlight areas of good caving potetential (instead of dozens of 3m "caves"). Similarly it could highlight climbing or ski pistes that offer a lot to do or a lot of challenge.
