While online maps aren't known for precise accuracy, there are times when seconds count (ie slight errors made by surveyors). Although these may be approximations within an acceptable range of error, the precision is needed for differential purposes. Europe is defined as west of the Ural Mountains and Ural River, north of the Caucas divide, Cyprus, Malta, Mediterranean islands owned by states predominantly in Europe, the Azores and Jan Mayen. Dependencies are not counted, however remote integral portions of sovereign states are. As always, suggestions, comments, and corrections are appreciated.
