london_tube_lines

London Underground and DLR line segments

A topologically-encoded representation of select London Underground rail lines, derived from OpenStreetMap data. These 394 LineString geometries, encoded using 406 arcs, depict transport paths between stations with stations marked as nodes along the lines. Originally transformed from a GeoJSON intermediary tfl_lines.json into TopoJSON format, this network configuration reflects the system as of February 4, 2018, and may not incorporate subsequent modifications or expansions.
