OSM Map Matcher

OSM Map Matcher matches GPS coordinates to existing OSM highways. Currently it returns solely the id of the matched highways.

Requires

• python-gdal
• psycopg2
• PostgreSQL with PostGIS and pgRouting

Convert KML to GPX

http://www.gpsvisualizer.com/convert_input

Create Database

createdb omm -U postgres;
psql -U postgres -d omm -U postgres -c "CREATE EXTENSION postgis;"
psql -U postgres -d omm -U postgres -c "CREATE EXTENSION pgrouting;"

Run script

python OSMmapMatcher.py

If the script exits, a GPX file is generated osm_date-time.gpx

1. Go to https://www.openstreetmap.org/edit
2. Drag and drop the GPX file
3. Digitize the road
4. Use #allryder as a commit message

Else a table with the matching OSM streets is created in the database

Background

• first OSM segment is found by closest distance
• all further features need to connect to previously selected feature
• feature is selected based on weighted distance and bearing
