Flussgebiete Deutschlands: Interactive map with computed river basins based on data from OpenStreetMap (in German language).

I developed some mapping-related tools that are available online for everyone:

GPX Viewer: Visualize and convert tracks, routes and way points in GPX, KML, Top50 OVL, PathAway and Magellan Triton ActiveTrk format.
GeoPosition: Compute, show and convert geographic (GPS) coordinates using the formats degree, minute, seconds, decimal degree, and UTM (WGS-84). The tool determines the time zone from coordinates and displays the times of sunrise and sunset for every place on earth.
Distance: Compute and display the shortest way on earth between two points - the Great-circle distance.
