Hi,
take care. taxi-drivers may not allways use main roads and driving also
more often to

Dear all,
I currently have access to 2 years, 20,000 taxi vehicles GPS trace (30sec
interval) of a large city in China. The OSM data quality of that city is
really bad. But uploading the raw GPS trace might have legal issues. Is it
possible to process the data to roads before I upload to OSM?

well, I have proposed a GSoC project which includes the functionality of of
all that Martin has mentioned, and much more. This would automatically take
GPS traces and give you a render-able .OSM data file. The project would be
capable of doing much more than just this (it takes care of cancelling
Hi Martin,
Thank you for your comments. Although 30 seconds are large interval, but
when I aggregate all data in a period from 20,000 vehicles, the trajectory
is very dense, and cover almost all the roads. For legal issue, I will
investigate that. But definitely I am not going to upload the

Would uploading only the points in a randomized order be okay for you?
The actual track (the connection between the points) is - for a 30s
interval, nearly useless for us.
generally speaking yes, although at rush hour times it could well be
In the Polish community there is a person who has access to a lot of GPS
tracks from trucks and he set up a great service:

That's an impressive amount of data. I kept thinking what can't I do with
so much data.
Your data not only identifies the road but also the traffic density of the
roads I.e. which roads are used frequently, which are the major roads.
In osm, classifying the roads into different category like
