[OHM] Construct road network of a city in China over past 40 years

[Rob H Warren]

Jingyan,

Why don’t you start by playing with either QGIS or Merkaantor and start making a few road networks? You can import a layer from OSM, bing, etc… as a contemporary background against which to reference points. 

When you can get comfortable with things, you can re-project (warp) an image of an old maps onto a layer and trace the roads from them.

> I'm a PhD student of transport studies from University of Leeds. I have no geography background. I want to study the change of road network of a city in China over past 40 years. So I have this vague idea to construct road network from old maps but I don’t know how to start. I have been reading OSM historical wiki page and related blogs since yesterday, and I'm amazed by works people have done. But due to my limited knowledge in this field, I still have difficulty to start. Is there any suggestion how can I get started? A little experiment would be fine.
