Hi every one,
Just to let you all know, the National Library of wales have just uploaded a High res copy of a historic map of Newport in Wales - which was surveyed around the time of the Chartist uprisings (Newport uprising)
We have uploaded the map as a whole at a reasonable resolution here:
https://commons.wikimedia.org/wiki/File:Newport_Tithe_Map.png
and also in High Quality sections here:
https://commons.wikimedia.org/wiki/St_Woolos,_Newport_Tithe_Map
I also plan to geo-reference the map when i have time.
Please let me know what you think!

(Cross-posting to the "wikimaps" list, which is the group particularly
concerned with old maps).
Hi Jason,
Whilst I'm sure the KML {{overlay}} template mentioned by Gauruv below
probably works, it's not really where things are at going forward.
The approach currently being developed for Commons is its own install of
the well-known NYPL Map Warper,
http://warper.wmflabs.org/
which is being supervised by its original developer Tim Waters under the
auspices of the Wikimaps project for old maps,
https://commons.wikimedia.org/wiki/Commons:Wikimaps
led by Susanna Ånäs. (Both on the wikimaps list).
There are various ways to get control-point data into the map warper, as
discussed by Tim in this post:
https://mail-archive.com/maps-l@lists.wikimedia.org/msg01101.html
In this case I would have thought the most straightforward approach
would be first to upload a copy of the tithe map onto Commons in its
native format, ie not as a GeoTiff, but as either an ordinary Tiff or a
Jpeg, whichever you consider the original format.
If you use the Commons {{Map}} template for the file description, this
includes a big friendly blue button to then install the image over on
the Map Warper.
As Tim writes, existing control points can then be added from a CSV
file, where the format is simply:
filename,x,y,lat,lon
ie:
IMG_1773.jpg,12,23,11.2,32.2
IMG_1773.jpg,12,23,10.2,31.1
from which there is script that an admin can use to add the data to the
map-warper.
This doesn't capture all of the data stored by Klokan Georeferencer --
eg the useful information as to what layer the image was georeferenced
against -- but is enough to get the geo-referencing data into the
system, and to then get it out in various formats, including serving
georeferenced tiles.
Sorry if it's all still a little bit round-the-houses; but with luck
everything should get a bit more streamlined, as we get more geared up
for large scale import.
(There are already a couple of thousand images on Commons with links to
external georeferencing, either at NYPL or the British Library; plus
ready to be uploaded to Commons a further 6,000 georeferenced map images
from the BL Mechanical Curator collection, just as soon as I've got
auto-categorisation a bit more worked out, with that number currently
increasing by approximately a further 100 georeferenced images a day
https://commons.wikimedia.org/wiki/Commons:British_Library/Mechanical_Curat…
).
As far as I know, nobody has yet actually used the script to import
pre-existing georeferencing onto the warper.wmflabs.org server, so I'm
quite interested to see how you get on!
Best regards,
James.

Hi there,
Does anyone know a good data-source of bounding information for
countries, states, counties, cities, etc?
Ideally, this information might be on Wikidata,
https://www.wikidata.org/wiki/Property:P1332 Co-ordinates of
northernmost post
https://www.wikidata.org/wiki/Property:P1333 Co-ordinates of
southernmost post
https://www.wikidata.org/wiki/Property:P1334 Co-ordinates of
easternmost post
https://www.wikidata.org/wiki/Property:P1335 Co-ordinates of
westernmost post
-- but there's very little there yet.
I'm asking because the big 50,000 map georeferencing of the British
Library "Mechanical Curator" maps should be going live in the next two
to three weeks.
A project target would be to get a back-end in place that can upload
maps to Commons *with appropriate categories* within 24 hours of an
image being georeferenced by a volunteer.
A batch of 3000 maps already geo-referenced is available as a test set.
I have had some success using Nominatim on the centre point plus points
40% of the way to each corner, to identify continents, countries, states
and counties that the map appears to be contained within.
But it would be good to know whether it is a map of a whole county, or a
map of several counties, or a map of a large feature within a county.
At the moment, my Nominatim script is a bit cautious, especially for
areas surrounded by sea -- eg Cornwall, Devon, Italy. It's not so good
at recognising that the map is a bit smaller than the encompassing
continent/country/region/county. It would be good to be able to compare
the bounding boxes, to determine how much of the county is in the map,
and vice-versa.
Does anyone know if such data is readily obtainable? Or if there are
good online services from which it could be got on the fly?
Cheers,
James.
Hi,
I'm increasingly seeing IIIF (International Image Interoperability
Framework) as a standard for serving images from repositories,
tileservers, etc -- especially for maps.
(eg Klokan offer an IIIF hosting service, and use it as part of the
stack for their Georeferencer; National Library of Wales for their map
projects, etc.)
Are people aware of IIIF ?
Does it have advantages ?
In the medium term, would aiming for an IIIF-compatible interface to the
proposed Wikimaps tileserver, or even main Commons itself, make any sense ?
With the Structured Data initiative for Commons now in the works, does
it make sense to make sure that there are properties baked in for
everything that would be needed to support IIIF? Also, to provide for
any functionality that could potentially be exposed through IIIF?
I see that there are going to be quite a lot of Wikidata people at the
Europeana Tech meeting in Paris on Thursday and Friday this week; and
also several presentations that will touch on IIIF.
Is it worth trying to put together a heads-up for Wikidata people coming
to this cold, as a background briefing on IIIF, and why these
talks/posters might be interesting to them?
As people with much more map experience than me, can I therefore ask
people on this list what they think of IIIF, and whether it is worth
getting on to our radar?
Thanks,
James.

At the IRC hour on Structured Data for Commons tonight,
(log:
https://tools.wmflabs.org/meetbot/wikimedia-office/2014/wikimedia-office.20…
)
Susanna gave the link to the impressive Wikimaps metadata spreadsheet,
https://docs.google.com/spreadsheets/d/1Hn8VQ1rBgXj3avkUktjychEhluLQQJl5v6W…
but this made me wonder: is every single map notable, in the sense of
meriting its own Wikidata Q-number ?
For example, consider
https://commons.wikimedia.org/wiki/Category:England_Delineated_%281800%29_b…
a set of fairly simple sketch maps of English counties, published in a
schoolbook in 1790.
Should each map individually have a Q-number ? Or instead, should just
the book and the edition have Q-numbers ?
The question is similar to that of books of engravings, such as eg
https://commons.wikimedia.org/wiki/Category:Views_of_the_Seats_of_Noblemen_…
Should each engraving have an individual Q-number ? Or instead, just
the book and the edition, with details specific to the individual
engraving (of which we may have more than one scan) kept on the
CommonsData page for the file ?
For maps there is some clear per-map metadata, even when they are part
of a set -- for example location, bounding boxes, etc.
Is it right to assume that there will always be a WikiData item for this
to live in? Or in some cases, would it have to live on CommonsData?
And will a copy of it need to live on CommonsData anyway, to facilitate
rapid sorting / filtering of a collection of images ?
Have there been any discussions that we know of in the Wikidata
community about this?

I would like to say that our project duration is until the end of this
year, and starting campaigning while we are working on the project will
dramatically reduce our capability to focus on development. But we are
responding to requests of having a user-friendly pipeline available for
georeferencing individual maps by the time of the British Library tagathon.
This will include the following steps:
-- unrelated to georeferencing: --
1. Launch the Template:Map [1], which will include a big, blue button as a
link to the Warper.
2. Use it in a batch upload with GLAMWIKI Toolset [2]
-- related to georeferencing: --
3. Enabling OAuth login from Commons to the Warper has been done.
4. Create a stand-alone big, blue button to add in Wikimedia Commons file
page for maps. Susanna and Jeph work on this.
4. Bot-add this button (a template) to a test set of maps. You might have a
proper candidate for such a set. Eventually we could add this to all maps.
André works on this, but you can help.
5. Create a gadget to manually add the button to any map file. I guess this
goes unassigned.
Additionally, but not before the beginning of October, we will
6. Create a form to transform data from the Information / Artwork / Book
templates into the Map template, that also includes the button, and will
include a locator map for the historical map
During the rest of the year we work to create a new user interface to the
Warper.
Creating methods for easy batch georeffing of maps is not included in our
plan for this year, but we will be happy to include it in a future funding
application. So we decided it will not take precedence over our current
plans.

It would be great if someone would put these files into the Old Maps
hierarchy, as that is where the bot could find the maps where the big blue
button will be included.

I think these are the things you propose to develop:
1. Create a mechanism for batch-adding files from Commons to the Warper
2. Create a mechanism for batch-importing georeferencing data to files
already batch-added to Warper.
3. Perhaps make a campaign interface?
All of these require considerable amounts of time from the community and
the developers. We were not prepared for this for this year, but I hope you
will be interested in committing your time to project planning and
resourcing for next year!
I hope our actions before the beginning of October will be beneficial in
the context of the BL tagathon!
Best,
Susanna
