[Tim Waters]

Hello,

here are some slides from my recent talk at State of the Map Scotland 2015.

http://www.slideshare.net/chippy/tim-waters-openhistoricalmap-state-of-the-map-scotland-2015

The conference was well attended and have quite a mentions of history.
Many of the talks were video'd

In particular interest - National Library of Scotland (NLS) Map
Library gave a talk, the Mapping Edinburgh’s Social History (MESH)
gave a talk. Chris Fleet from NLS also gave participants a wonderful
tour of the NLS map library and we saw a huge range of maps from
ancient to modern. Mapilliary gave a talk showing how they can view
photos from a range of times, and mentioned that historical images
from an image archive are being added into the system (I think in
Sweden?).

Comments around OHM were along the lines of:

It being amazing potential for education.
How can you tell looking at OSM whether an edit was because the
feature changed or was wrong.
How to record changes in OHM/OSM for things that change over time (and
whether the growth of OHM would help this).
Types of changes "succeeds, replaces, subsumes, within etc"
Accuracy of historical maps.
Extracting social and statistical information from maps.
"super-imposition" (?) where you merge lines and features from
different times which are the same feature but because traced from
other maps may be slightly offset.
Disused railways were mentioned of course!


Cheers,

Tim
