I work for Esri on tools for ocean science. I'm affiliated with the National Center for Ecological Analysis and Synthesis, and recently graduated from at nearby UCSB, where I studied the global shipping trade in an ecological context (thesis).

Source snippets I post on GIS.SE are dedicated to the public domain.

comment How to make a routable graph from a Point and a Line shapefile, using Networkx?
@Pep: right, you have a couple of options. If you're looking to build a permanent data structure, you could edit the line segment and insert that point, by adding two new segments when you find the closest one. If you just wanted to do it one-off, then compute the linear distance to each closest vertex, then do the cost path to those two locations and see which one is shorter with cost + dist_to_vertex.

OK, understood. First you'll need to co-register your points to your network. I think the approach I outlined here should work: gis.stackexchange.com/questions/396/…

Yes, you can use the read_shp function of NetworkX to import the shapefile into a graph model: networkx.lanl.gov/reference/generated/…

revised Problem with SetValue method in ArcGIS 9.3
shorten the path to prevent the code from breaking across the screen; the user has a correct answer and this path isn't necessary for understanding the problem.

archydro has a dedicated support forum that may also be helpful.
