I picked up the following comments on the acuracy of your maps that may be of interest off of our local community website eastdulwichforum.co.uk

> I have looked at this Website but the sites mentioned are not precise, the sites that I saw then were blocks away from those marked

I’ve seen enough people saying this to have me wondering whether there is a systematic error in their geomapping software.

In fact, if you look at this page, [bombsight.org], they are fairly upfront about some possible sources of error that may exist in their different data sources. But I do trust that they’ve checked that the process transforming the original data records to the maps we’ve been given hasn’t introduced any further error.

There is presumably scope for checking the original data records against clear recollections of folk like computedshorty. Perhaps such work has already been done. Anyone who comes across any academic papers relevant to this project, please do mention them here.

There are not a lot of people that are still alive to confirm the actual sites. It looks to me that a transparent film had been overlaid on the map then the sites added, as they are to my memory being at least 400 yards to the right of the sites shown.
My father was one of the Civil Defence Wardens at the Dulwich Library, he was a very precise man so marking a map would be dead on. Taking on the fact that his own home was damaged so close to the Library would mean he would be aware at the time even if not on duty.
Betweeen Crystal Palace Road and Goodrich Road the site I am talking about is mostly in Landcroft Road where five houses were very badly damaged, ( they have now been only four house built to replace them )
The site extended to Lordship Lane where the backs and tops of the houses were damaged.
The site can be seen as vacant in the Google maps, and in others show the new houses, and the damaged ones, and rebuilt, back additions and roofs, chimney stacks of a more simple style replaced, ( no chimney Pots on top ) of those in Lordship Lane.
There are records to be seen at the Council Offices in the Boro, but I am not able to get there.

Certainly the bomb that fell on the boundary between my house and that of the adjoining Therapia Road is not recorded in the correct spot – the nearest red blob being approximately 100 yards too far west.
