3D mapping of Oldham landowners in 1829

I'm currently trying to make a 3D model of Dunn's map of Oldham in 1829.

Here are two versions:

Dunn's map of Oldham 1829



It's easier to navigate on a touch screen. If you're on a standard PC then zoom in by pressing ctrl + shift and the up button.

Still work in progress as I haven't entered the whole of Dunn's index of landowners and occupants.

Quick summary of how to do it:
1. geo-reference the map in QGIS
2. draw the polygons of the buildings, remembering to add a column in attributes for number of floors. I've estimated this as I don't know the real heights, so for cottages I've put 2 floors, houses 3 floors and big buildings like factories and churches I've put 6 to make them stand out.
3. use the 'threejs' plugin in QGIS. This automatically converts the floor heights into the z co-ordinate - really easy. It makes it into a html file for you with associated files, which you just then upload to your webserver in one folder. Magic.

Commemoration of the execution of 17 Luddites, York, 19 January 2013

On Saturday 19 January, York's Alternative History held an afternoon of talks and commemoration for the Luddites tried and executed at York. placards outside York Castle In the huge space of the Guild Hall, Adam Gutteridge , one of the organisers, introduced the themes of the day. His speech echoed the two interesting articles publicising the event in the Guardian (by local historian Paul Furness, here , and by another organiser Helen Graham, here ). They argue that now that York's industrial economy is no more (chocolate and railways), York has remade itself round the past: an economy of tourism. Yet the past as presented to tourists and indeed to residents, is a sanitised and normalised history, centring round Vikings, medieval religion, and Georgian middle-class pleasures. The recent York 800 celebrations had no place for the popular protest and resistance that had a distinguished history in the city. I began the talks by explaining the context and meaning of the

'As I tried to bludgeon Chartist demonstrators in the square'

The quotation above of course is made up by Half Man Half Biscuit, in 'Letters Sent.' Chartist demonstrations almost automatically bring to mind urban settings of protest - particularly 'monster' meetings in Georgian and early Victorian civic squares: Stevenson's Square in Manchester, Clayton Square in Liverpool, Paradise Square in Sheffield, and so on. Many of the big meetings - and conflicts - occurred in what should be 'public' space, but in fact were not freely open to all, but controlled by local elites opposed to any threats to public order. Yet Chartist demonstrations were not solely urban in character. Partly because they were being forced out of 'public' spaces in towns, and partly because inhabitants still had connections with the countryside, 'camp meetings' and demonstrations also occurred in rural areas, especially on moors and commons. Processions from towns out to the more remote moors connected urban with rural. Monster meetin
