Inspired by a recent (blatantly stolen and uncredited) post showing all football pitches in Europe as a red dot, I tried my luck at depicting all tennis courts in Europe.

Source: OpenStreetMap.org Tools used: Overpass Turbo and QGIS

Remarks: * This was more an exercise in using the tools above than creating a stunningly beautiful map. * OpenStreetMap data tends to be a bit less accurate in the Eastern part of Europe. It is not that bad, though and absolutely good enough for a general overview. * First post ever and non-native speaker. Please be gentle ;p

P.S. The original football post here.
