More maps to follow in a few days.

On 7th and 8th November (in 3 weeks' time), there's a 2-day workshop organized in Lviv, Ukraine. The subject is  "The Digital and the Visual: New Approaches to Urban Studies Research of East Central Europe”. 
Detailed programmed available in this pdf (in English).
Workshops will be held in English and Ukrainian.
Access is free of charge, but you need to register your interest in the e-mail address provided in the abovementioned pdf - by 20th October.
Ref. "how to get there": for UK, best access is via cheap (aka "budget") airlines, which fly to Krakow and Rzeszow, and other airlines connect from Western Europe to Krakow. From there on, you can take a train or a coach to Lviv. If you drive across the border in your own, or rented vehicle, you can expect to be held up for many hours on your return journey though.

This time a somewhat bigger Mapster update:
1.    some 330 sheets of the Russian 1:84,000 map (2-verst), of which approx. 200 come from the University of Warsaw, and some 120 from the Library of Congress. Most maps are dated 1914 -  1917, while several dozens are later, 1920s reprints, some with stamps of the original "Archiwum Map W.I.G." A few more sheets might become available in the autumn, but next large update can be expected no earlier than mid-next year.
2.    Around 20 sheets of Russian and Soviet 1:42,000 map (1-verst), mainly from north-western Belarus. Some sheets are incomplete, they will be re-scanned and updated in the autumn. In a few days, a couple of extra, joint sheets (x4) of a WW1 edition of this map will become available.
3.   Through kind support from Mr Jean-Luc Arnauda of CNRS, we have received permission from Université Paris 8 to add to Mapster approx. 290 sheets of the German 1:300,000 Osteuropa map (300 dpi). They are, very well scanned and hard to get, first editions from 1942/1943 and provide coverage well east of Moscow, reaching, in the south-east, to Kazakhstan. We have also added, courtesy of our Czech friends, some 50 other sheets of this map type, mainly Central Europe (400 dpi). They include some very interesting military-geographical (Mil-Geo) editions with overprints and extended description on the front and back of each sheet. Three maps show the area of Pripet river (Pripetgebiet), a few others come from a large set on the accessibility of the Carpathian Mountains (Durchgängigkeit Karpaten), and a single sheet is T50 Tarnopol, with extra information and town plans of Czortkow and Tarnopol on the reverse. Some of the 1:300,000 sheets are very late editions (January - April 1945), e.g. Breslau, Berlin, and one irregular sheet of a „Strassenkarte” marked as Geheim (Secret) dated for 30th April 1945. It shows the area south-west of the Czech town Ústí nad Labem). All sheets available via Mapster index (please note - VERY LARGE index sheet - takes a long time to load!)
4.    Some 45 sheets of the German 1:500,000, WW2 edition, mainly USSR, Central and South-Central Europe, 400 dpi.

We have failed to note an important event: on 13th June this year, Col Robert Bauer defended his PhD thesis on the "Transformation method for points in a non-uniform triangulation network into the uniform coordination system" (in Polish), which allows accurate callibration of maps, including those by WIG, for navigational (gps) purposes. Congratulations!

Mapster:
Because we’re rather busy at work, we’ve had to re-schedule map updates. This time, we have added about 40 sheets to the German, WW1, 1:100,000 map of western Russia (Karte des westlichen Russlands): H18, K28, K37, L25, O14, O16 - O18, O35, P17, P19, P31, P32, P35 - P38, Q11, Q14 - Q16, Q36 - Q38, R36, R37, R40, S36, S38, S41, T35 - T37, T39 - T41, U35 - U38, U40 i U41.
Some of them are different editions, e.g. 1914 and 1915, although no apparent updates are visible. Most of them are courtesy of the University of Berkeley library, and the Library of Congress, due to the efforts of our collegues from www.easteurotopo.org, for which we are very grateful indeed. Other sheets have been provided by private collectors.

Additionally, three German 1:100,000 (Grossblatt) sheets have been added: No 37, 67 and 317.
