Learn about “Working Digitally with Historical Maps and Geographical Information” — Portsmouth, June 2012

The Great Britain Historical GIS team, the people behindA Vision of Britain through Time and other resources like Old Maps Online, are running a one-week training course in Portsmouth on June 18th to 22nd 2012.

It is aimed at anyone wanting to create a digital resource from sources which are both historical and geographical – most obviously old maps, but also historical census information or geographically rich text. You may be planning on building a “historical GIS” or simply a web site with many maps – one aim is to help you decide the most appropriate final result for your particular sources and goals:

• We will equip you to do a small project in historical GIS or map-based digitization; or to plan and manage a larger project – so we include both hands-on training with GIS software, and sessions on source selection, project planning, copyright and budgeting.
• Hands-on training emphasizes Quantum GIS, a capable free open-source alternative to the commercial GIS software that historians and ‘memory institutions’ cannot afford, but most skills will be transferable to other programs.
• Quantum excels in accessing standards-based on-line GIS services, such as web map servers providing base maps. We will show you how to avoid starting from scratch, by accessing new online services and download facilities within the GB Historical GIS.
• Members of the GB Historical GIS team will teach core modules, but the course also features case studies presented by other members of Portsmouth Geography, and speakers from the Ordnance Survey, British Library and the National Archives.
• Hands-on sessions will have a maximum of ten attendees per leader.
• Our campus adjoins Portsmouth’s historic dockyard, home of the Royal Navy for five hundred years. The course includes a visit to the Admiralty Map Library, one of the world’s great historical map libraries but open to visitors only by special arrangement, and a dinner at the Royal Naval Club.
• Portsmouth is an hour and a half from London by train, and easily reached from London Heathrow, London Gatwick and Southampton airports. Car parking can be arranged.

Portsmouth Geography is the base for the Great Britain Historical GIS project and several other major online resources. Uniquely, we have not just twenty years experience in historical GIS, but over ten years of experience in employing Geographical Information Systems technology in standards-based digitization projects, with funding from the UK National Lottery, the Joint Information Systems Committee and the European Union.

Course fee: £849, including lunches, refreshments and the Working Digitally dinner. Overnight accommodation for four to six nights is available for £37.50 per night (bed and breakfast). For more details and to register, visit:

Tidying house before the move

We have just added a few more places and units, and a lot more names and relationships to A Vision of Britain through Time:

• The 77 new “places” include all remaining “Ancient Districts” — Hundreds, Wapentakes, ancient Boroughs etc — except those in Wales, so they are findable from the home page. We also went through the descriptive gazetteer entries that were so far un-placed, and have created “places” for several interesting ones that were over 1,000 words long and were not linear features; for example, Salisbury Plain and the Carse of Gowrie:

Salisbury Plain

• The 151 new units include the seven “Conurbations” defined by the 1951 census, such as the West Midlands, the useful part being that we include the listings of which local government districts were parts of each; and 84 wards within the four Scottish cities, again as listed in 1951. There are of course many, many more Wards we could add.
• The 2,745 new names and 1,309 new relationships are partly in connection with those new units, but mainly the result of work to systematically link the 1831 census’s parish-level table into the system: the unusually detailed occupational statistics in that table are already accessible within the web site, but many parishes lacked data because the names or other information in the census list did not match. One key aspect of that is that although we have always included the information from Youngs’ Guide to the Local Administrative Units of England about which parish was in which hundred, we were not making practical use of it ourselves so various errors by Youngs and by ourselves persisted. That has now changed, although we have still to re-load the 1831 statistics to make them more complete, and Welsh administrative geography remains a challenge.

Obviously, this has been a general tidying-up operation, and the context is that we are starting to transfer the whole web site to a new server. We will not be announcing any further changes to the content until that migration is complete, in a couple of month’s time; but there will then be a lot of additional features in the software.

Fortunately, there will be plenty of developments with the separate Old Maps Online site in that period, so there will be no shortage of news on this blog.

Detailed occupational statistics for individual parishes in 1881 now on-line

We have just made a very large addition to the statistical content in A Vision of Britain through Time: detailed occupational structure data for each Civil Parish in England and Wales in 1881. However they are a little hard to find.

They have actually been in the underlying database for some months, and were the basis for summary data by occupational “Order”. The reason why they were not visible is that there are over four hundred different occupational categories, and our software for handling statistical “themes” is programmed to ignore data which cannot sensibly be graphed.

What we have now done is made the data accessible under the “Census Reports” option for each parish. You still cannot see a graph, but you do get a tabulation.

This is a bit of a cheat, as unlike all our other census data these numbers never appeared in a published census report. They were computed for us some years ago by the History Data Service at the University of Essex, from the individual-level data from the census Enumerators’ Books as computerised by an army of family historians coordinated by the Genealogical Society of Utah. Data for Scotland were not available.

However, it is not completely a cheat as, firstly, the data we are presenting for Registration Counties in our listing of table 10, “Occupations of Males and Females in the Division and its Registration Counties” from the 1881 report titled Tables: Ages, Condition as to Marriage, Occupations and Birthplaces of people are exactly what they say they are. For example, here are the data for Herefordshire:

http://www.visionofbritain.org.uk/census/table_page.jsp?tab_id=EW1881AGE_M10&u_id=10134778&show=DB&min_c=1&max_c=2

However, if you go to the original report you will find that the only data for sub-county units in table 10 are for Urban Sanitary Districts with populations over 50,000. We have made it possible to drill down from the Registration Counties to Registration Districts, then to Registration sub-Districts and finally to Civil Parishes by using data from the Enumerators’ Books. Note that a great deal of work was done at Essex to group the roughly half million character strings defining occupations in the data supplied by the Genealogical Society of Utah into the 400-odd detailed categories used in the published table, so this is not much of a cheat at all. One limitation to the data we have added is that they exclude persons under 15 or over 65.

Although the data list “categories” not the actual occupations given by respondents, they are often very specific, such as “Toll Collector, Turnpike Gate Keeper” or “Painter, Glazier”. Here for example are the data for the parish of Selbourne, Hampshire:

http://www.visionofbritain.org.uk/census/table_page.jsp?tab_id=EW1881AGE_M10&u_id=10202036&show=DB

Summarising, the way you reach these data is:

• Search by place name from our home page.
• Once you reach the relevant “place page”, click on “Units and statistics” in the sidebar on the left.
• Select and click on a unit whose suffix includes “CP”, such as “AP/CP” or “Ch/CP” (meaning a unit that was originally a Chapelry). The data may also be available for units with status “RegD” or “SubD”.
• From the unit’s home page, click on “Census Reports”, which should be the last option in the sidebar.
• You then get a list of available tables in date order. For 1881, click on “10: Occupations of Males and Females in the Division and its Registration Counties”, and you should get the listing.

UK Archives Discovery Forum Meeting (21st March 2012)

The National Archives will host a day for the United Kingdom Archives Discovery (UKAD) Forum in March again this year. This network is a collaborative group of archives and other information professionals who work towards opening up data in order to promote the use of archives through the sharing of ideas about online access to archives and their data.

At last year’s meeting project director Humphrey Southall presented about A Vision of Britain through Time. This year will see a presentation and demonstration of the new Old Maps Online website being launched on 29th February. There will also be a presentation by another member of the steering group for that project, Kimberly Kowal of the British Library, who will speak about their map crowd-sourcing project.

Attendance is free but places are limited. See their website for details on how to book a place.

Working with our descriptive gazetteers

A couple of my recent posts have been about defining additional places. This work has partly been about finding geographical locations for administrative units which were previously defined by hierarchic position, meaning the county or district they were part of. However, it has increasingly been about finding locations to go with entries from our collection of descriptive gazetteers, mainly from the late nineteenth century.

So how are we doing with this task?

Name of Gazetteer	Total Entries	Placed Entries
John Bartholomew’s Gazetteer of the British Isles (1887)	55,516	23,137
John Marius Wilson’s Imperial Gazetteer of England & Wales (1872)	29,411	18,902
Frances Groome’s The Ordnance Gazetteer of Scotland (1885)	7,268	1,952
Samuel Lewis’s A Topographical Dictionary of Ireland (1837)	3,939	36
W.H. Beable’s Russian Gazetteer and Guide (1919; just some Estonian demo entries)	5	4
TOTAL	96,139	44,031

You will see that even after all this work more than half the descriptive entries are not linked to places, so don’t assume you can’t find somewhere in our system until you have directly searched our descriptive gazetteers via the relevant expert search form:

http://www.visionofbritain.org.uk/descriptions

A lot of the “un-placed” entries are for physical or linear features, like mountains, rivers and railway lines. However, many are simply for small settlements. For example, there are 9,177 un-placed Imperial Gazetteer entries of two hundred characters or less, which have so far not been visually inspected. Of these, 492 are for “a village”, 1,174 for “a township” and 3,396 for “a hamlet”.

A few more tips:

• The relative locations given in these entries, such as “six miles north-west of Newtown”, often seem to describe the main settlement of the parish containing a township or hamlet, not the place being described. This is one of the reasons why locating some of the Welsh townships is proving so hard.
• Where descriptive entries give locations that are just plain wrong, Bartholomew and the Imperial Gazetteer often seem to make the same mistake. For example, they both locate Ynysawdre 3 miles south of Bridgend in Glamorgan when it was 3 miles north. There is a strong suspicion that the various gazetteers copied much material from one another, including their errors. NB our aim is always to provide an accurate transcription of what the historical writer said, not to correct any errors they made.
• Most settlements end up with two linked gazetteer entries, one from Bartholomew and the other from the Imperial Gazetteer or, in Scotland, Groome. Our system then selects the entry with the most appropriate length to appear on the main page for each place, below the map. Our rules for selecting the entry are a little complex, but what this means in practice is that if the entry on the main page is from Groome or the Imperial you will not find much additional information on the “place writing” page, unless it is a really big place with lots of entries, or if there are linked references from travel writers. However, if the entry on the main page is from Bartholomew it is very likely there will be a more detailed entry linked from “place writing”.
• Some of those linked entries can be very long. For example, the Groome gazetteer entry for Edinburgh contains well over 100,000 words — the length of a substantial book.
