Good work Tim. It seems we have a lot of people interested in this. :-D In regards to the NLS maps, I am having some trouble with the sample files sent through to me. I sent them on to the guys from NYPL and even they struggled. I've just contacted Chris at NLS to see if he can send me them in a different file format.
Meanwhile there is a chance to improve the map vecotorizer tool. Currently the way it works leaves a gap between terrace buildings. If you, or anyone you know may be able to help solve this GIS problem (including post processing), please get in touch.
