Calculates matrices of both correlations and distances between all pairs of bicycle hire stations (London and NYC). Distances are routed with routino, using the weightings for bicycle travel specified in /data/routino-profiles.xml. Routing requires an OSM File which is then converted with the routino planetsplitter command to make a bunch of .mem files with a designated prefix (here, lo or ny). If these files don't exist, then planetsplitter is called by getStDists.py.

Note that splitting a .osm.bz2 does not work, even through it is supposed to with routino.

getDists.py reads the station_latlons.txt file and calculates all inter-station distances. This takes a really long time! For example, London has ~750 stations, and if each routing takes ~2s (actually slightly faster), this amounts to 156 hours.

Correlations are based on ride data downloaded from repositories for the respective cities.
