Connectivity Matrix of Vertices within a Line

Recommended Posts

I've been wondering, if there's a way to generate a connectivity matrix for the vertices of multipart polyline. For instance

a_____b____c____f

|

|

|

d

a is connected to b

b is connected to a, c, d

c is connected to b,f

d is connected to b

f is connected to c

If I can get this information, then it'll be helpful for me to build a web-app. Any suggestion?

Hi there,

the procedure in arcgis 10.1

arctoolbox > Data Management Tools > Teatures > Split line at vertices

then

arctoolbox > Conversion Tools > To Coverage > FeatureClass to Coverage

the attribute table of the "arc" created by coverage, shows which vertex connected to which one

the problem is how to create a matrix similar to yours

It worked man. For my purpose, I had to build the coverage 2 times. One for getting the NAT (node attribute tables) and one for updated ARC.

I wonder why doesn't shapefile contain any topological information? What were they thinking?
