localid is the key into the RLIS street data.
So I was surprised to find 2408 data segments with localid set to 0.
Turns out these are the YamHill county part of the data, and are further coded with type=8224="unknown type Yamhill Co. only"
I am currently ignoring these segments when generating the merged networks. I doubt this is a problem: there is only a small overlap between this data and the OSM coverage area I am currently using (in the far South West) If this does becomes a problem we will need to augment id keys for the RLIS data in some way.
