[OSM-dev] Import a huge amount of GPS data

[Jingmin Chen]

Dear all,

Thank you very much for the active discussion. Again, uploading the raw
data is legally impossible. But contributing processed information will be
very interesting as OSM data in China is really bad. To what I understand,
there are two possibilities that are technically practical, and I would
like to have more advices from you on which methods/tools to use.
1. Aggregate GPS points to generate centerlines of the roads. Serge
mentioned TileMill?
2. Intelligently infer the road type according to the GPS speed.

Cheers

J
