Hi Jatin and Sunburned, That's right, JTS has capabilities to create graphs. It is used for many geometry operations.
To add graph capabilities to OpenJUMP, there are several possible design choices. Building something over JTS api Linking Features to a graph api like JGraphT, Jung,... I choosed the second because - I found it more easy to understand - I thing graph problems in GIS often need attributes and are not pure geometric problems - I could easily uses algo implemented like sortest path, node order... I do not say this is the only choice. Just say that it is important to define the goals and to study how JTS can help and how an external graph library can help. Would be nice to list a few use cases for graph capabilities. Michaël Sunburned Surveyor a écrit : > Jatin, > > I think there are already some graph capabilities built-in to JTS.
