IMPROVEMENTS Internal Junctions • OSM does not identify ‘intersection link’ roads (Example A) and ‘connection roads’ (Example B) • Identified such internal junctions to facilitate routing, guidance and map display Way Sectioning • Sectioning for long segments in OSM. Golden Gate Bridge is one intact way in OSM. It gets chopped into smaller segments to facilitate embedded traffic.
(MANUAL EDIT) • Critical for guidance • Requires official data (sparse) or Street Level Imagery • Data model proposed by Telenav gained wide acceptance in N-America

COULD HAVE DONE BETTER? • Telling people what we were planning in advance • Allow plenty of time for discussion • More research into local mapping practices + asking more questions • Be unafraid to step back / stop in place and rethink what we’re doing • Less focus on quantity over quality • Community training
