I'm working on a shapefile of Brussels (QGIS 3). This shapefile contains all the streets in Brussels, see below.
With the attribute table, I have an
"Y" position for each line (debut and end),
I used this to create nodes at each debut and end of the line in Oracle Spatial.
Now I need to check if
- all the nodes are not in double
- They are all connected to another
- There isn't one node so close to another that a travelling test would take the wrong way
For now I'm just Using the network analasys from Processing Tools, and I take one node on the left and one on the right (then N and S etc) and ask for the shortest path to see if it's OK. But There should be an easiest way that provides to do an analysis on all the Network !
==> SO I'm looking for - a way to calculate a lot of shortest path easily (maybe with a script) or - another way to see if each point is really connected to the rest.
Maybe I could take a point in the center and test it with all of the point on the external (like the boarder of my shp?)
