Mapping extinct streets of Belfast

There are some small streets in 19th century Belfast that were never mapped before they were demolished. They do appear in street directories. Is it possible to recreate a map based on street directories?

Street directories

The great thing about (some) street directories is that they list every address and intersection in order. In this way, they preserve a large amount of data about the topolocical relations between these features.

Networks

It should therefore be possible to map them out as a network, even if the position of each node (address or intersection) is not known. Think of it like a subway map, where the precise positions are not as relevant as their relations:

Geocoding and layout algorithms

Some features still exist today, and can be geocoded to give their coordinates to "anchor" the network at various points in space, like pinning strings of beads to a board.

Assuming that each address has a similar length of frontage can give more clues than just using the intersections alone. Layout algrithms should be able to place the addresses with no known positions in a street-like fashion (try to to make the strings straight-ish, try not to cross them oover where there is no intersection, etc.)

The best results for a proof of concept so far have come from Cytoscape:

Mapping

It should be possible to eventually convert strings like this into LineStrings and other relations used in GIS/mapping systems, which can be overlaid onto modern or old georeferenced maps.
