I am trying to obtain road-network data from OSM file using pgrouting and for this I am following this tutorial:
The format I am looking for is following(bidirectional)
OSM_ID_1 OSM_ID_2 legth OSM_ID_2 OSM_ID_1 legth OSM_ID_3 OSM_ID_2 legth OSM_ID_2 OSM_ID_3 legth OSM_ID_3 OSM_ID_4 legth OSM_ID_4 OSM_ID_3 legth OSM_ID_2 OSM_ID_4 legth OSM_ID_2 OSM_ID_4 legth
and so on...
I find that they have missing steps. At the end of this chapter they download the data in form of OSM files. http://workshop.pgrouting.org/chapters/installation.html
Next chapter, they are using
data from the "workshop directory":
I have no idea how the got from one step to another.
Can anyone help me with this?
