I have an existing road network in a shapefile. I need to add two extra links/roads.
I added these as lines to the shapefile, making sure to 'split' the line in the original network to make a junction that the new line could 'snap' to. However, when I try to build the network it doesn't work.
It works fine when I delete the new road so it must be something I am doing wrong with the new road.
Are there stages I am missing?
Do I need to fill in the attributes of the new road (length) etc., and what is the quickest way to do this if so?
The dataset has many attributes so if I need to fill them in for new links, is it possible to find out which ones are needed in order to make the network? (as a lot of information is probably not used).
