Open data, no paid services
Greek coastline and land polygons: OpenStreetMap contributors, via osmdata.openstreetmap.de, retrieved 23 October 2026, ODbL. Worldwide overview: Natural Earth 1:50m land polygons, public domain (Made with Natural Earth). Both datasets are processed locally and shipped with the site. No external map tiles. Greek water grid uses an approximate 600 m coast buffer; world grid uses 0.1° cells (about 11 km north to south at the equator, with east to west cells shrinking toward the poles) and small islands/straits may not be represented.
Map display uses D3 (Mike Bostock, permissive ISC licence) and a locally rendered canvas. Routes calculate in the browser. No paid map, routing or geocoding service.
