Using the Austro-Hungarian 1910 High Resolution Maps
 
Greenwich and Ferro: Although today the most standard reference line of longitude is that of 0 running through Greenwich England, it wasn't always that way. In fact there were and are many different ones. The maps in this set use zero degrees running through the town of Ferro in the Canary Islands as was common in Europe at the turn of the century. To convert from Greenwich to Ferro, one must add 1740' the Greenwich longitude. To convert from Ferro to Greenwich, you subtract 1740' from the Ferro longitude.

If your geography is pretty good, the following method works ok: click on the Index Map. Locate the area of interest. For each square on the map, there's a town/city name associated with it. It looks to me that it is the Hungarian rendering of the name of largest city in that square. For example, if I wanted to find the map that contained Czernowitz, I would look around the area where I thought it to be on the Index Map, and there you will find 'Csernyivci'. You can just click on that square, and the map should start to become visible in your browser.

Now, looking at the Index Map again:  if you look all the way to the right along the row that Csernyivci is in, you will see 48 -- that is the latitude associated with the centre of the box. If you look up or down along the column where the Csernyivci box is, you will see 44 -- the longitude (east of Ferro in the Canary Islands) running through the middle of the box. So the centre of the box has latitued/longitude 44-48, which not coincidentally, is the file name for this map: 44-48.jpg.

Here's another example, and probably reflects the way most of us would use the maps.  Suppose I were interested in the map that contained my ancestral home of Podgaytsy or Podhajce Galicia which I know is at 4916' N; 2508' E (greenwich). Now the latitude is correct, but the longitude 2508' E of Greenwich must be corrected if we are to get to the right map. We do this by noting that we must add 1740' to the Greenwich figure to get the Ferro figure. Thus the Ferro longitude for Podhajce is (25+17) (08+40)' or 4248' East of Ferro.

Now if you've looked at some of these maps, you will have noted that for any particular square, the longitude number runs through the CENTRE of the square with half a degree on either side. Thus if we pick the 42-49 map (which seems logical), we will get a range from 4130' - 42 - 4230' and we have missed our target of 4248'. So, our target lies on the next map to the right, the one that contains 4230' - 43 - 4330'. Thus we should look for map 43-49.jpg.  Selecting this map, we need to manually move through the map using the scroll bars (or the arrow keys) , looking for Podhajce and we find it right there at 4916'N ; 4248'E (Ferro).

The website that these maps came from is:  http://lazarus.elte.hu/hun/digkonyv/topo/3felmeres.htm

If you need maps other than those I've posted, you can go to the website above and get them.  As you can see in the table below the Index Map, not all maps are available, as some were apparently never published.

Finally, I was able to find the lat/long of some ot the towns in Transnistria, Budy, Bar, Bershad, Shargorod, etc., using Google Earth.  Then I converted the longitude to Ferro, and I could usually determine which map sheet I was looking for. If you do use this method, make sure when you type in the the town in Google Earth you type it as:  TownName, Ukraine i.e., bar, ukraine  otherswise you will get maps of where all the bars are in Ukraine ;-)
