Using ArcGIS 10 Network Analyst, I've created small python script that calculates OD matrix between certain locations, i.e. not between each origin and destination but for each origin I have a set of destinations that I want to calculate routes for. I end up with 17 results saved as a .lyr file (don't necessary need to save them on hard drive as such). I would like to merge those results together. The problem is a OD Cost Matrix Layer is in fact a group of layers and I'm only interested in layer Lines.
To sum up: if layer is OD Cost Matrix Layer (group of layers) and Lines is one of the layer in that group and I want to use Merge tool to merge a few of such Lines layers - how do I do it as
is obviously giving me an error of input not being a table view.
