Just mapped my very first road / how to post-process DGPS?

Posted by lindi on 24 July 2008 in English (English).

I finally managed to borrow a BU-353 USB GPS receiver and added my very first roads to OSM. Here's my complete workflow:

1) gpsd -d ntrip://lindi:$ -f /dev/ttyUSB0 -N -n -D 1

2) echo rw | nc 2947 > a.dump

3) gpsbabel -i nmea -f a.dump -o gpx -F a.gpx

4) open a.gpx in josm, edit map, upload

Any idea how I could I apply DGPS corrections as a post-processing step? I don't always have access to internet.
