Given the following test shapefile, which is made of polylines only:
I was able to reproduce the nodes of the spatial network represented in the shapefile:
import networkx as nx
import matplotlib.pyplot as plt
G=nx.read_shp('C:\Users\MyName\MyFolder\TEST.shp') #Read shapefile as graph
pos = {k: v for k,v in enumerate(G.nodes())} #Get the node positions based on their real coordinates
X=nx.Graph() #Empty graph
X.add_nodes_from(pos.keys()) #Add nodes preserving real coordinates
nx.draw_networkx_nodes(X,pos,node_size=100,node_color='r')
plt.xlim(450000, 470000)
plt.ylim(430000, 450000)
Basically I have used a temporary graph
G to extract the positions of the nodes that eventually appeared as part of the graph X. This seems to have worked just fine.
My question: following the same idea of using G to extract information from the shapefile, how could I plot the edges?
If I do something like this
X.add_edges_from(pos.keys())
Then I get this error, pointing at the line above:
TypeError: object of type 'int' has no len()
