Coping with OFDS datasets with differing levels of granularity

[stevesong]

A problem I had not foreseen is the challenge of consolidating two OFDS datasets with differing levels of granularity. For example, if one operators lists both PoPs and manholes as part of their OFDS network data and another operator's OFDS dataset just has PoPs, consolidating them is likely to be a challenge. The operator with PoPs and manholes will have much shorter spans, even if it is the same network infrastructure as the other operator that only includes PoPs.

One solution might be to have a tool that strips out all nodes except those labelled as PoPs and rebuilds the network spans to match. If not PoPs only, perhaps an agreed subset of node types.
