cslraju Posted April 5, 2013 Report Share Posted April 5, 2013 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?

yousef2233 Posted April 6, 2013 Report Share Posted April 6, 2013 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 1 Quote Link to comment Share on other sites More sharing options...
Team_Evil Posted April 6, 2013 Report Share Posted April 6, 2013 cslraju do you know about the line segmentation...????? Use the feature as polyline M, then use the grips to connect the various vertex...!!!! Good luck Quote Link to comment Share on other sites More sharing options...

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? Quote Link to comment Share on other sites More sharing options...
yousef2233 Posted April 7, 2013 Report Share Posted April 7, 2013 i'm glad that it worked, Featureclasses are based on theses table, actually there is nothing in geodatabases but spatial tables, shapefiles are a common and old format i dont recall the way software save them, but if you want to know exactly take a look at Modelling Our World (ESRI Press) Quote Link to comment Share on other sites More sharing options...
