1:200,000 maps of old Hungary

February 10, 2010: Maps project discontintued - maps available elsewhere
My efforts to digitize the 1:200,000 scale sheets of the so-called 3rd Military Topographic Survery of Austria-Hungary have become obsolete years ago, so, I decided to end this project. The same sheets I was about to scan - in fact, even more of them - were made available by Budapest's ELTE University, followed by the collection of the 1:75,000 series by the AtHu75 project. And add to these the digitized and publicly available part of the Arcanum map products already online - and even more coming. All these led me to abandon the RadixIndex map project and focus on non-duplicate data.

Still, if anyone as a subscriber feels that (s)he really needs a sheet section to be prepared by me, please, contact me at RadixIndex support to see if I can help.


For years I've been a keen collector of 1:200,000 map sheets covering old Hungary, and now I'm pleased to launch a new special feature of RadixIndex by posting the first sheet of the maps from the years around World War 1. I hope that maps will help to familiarize with the settlements researchers observe, and probably, bring some fancy material to dull written records.

Background information
These maps were prepared for the military, and are based on the 1:75,000 series of maps of the so-called 3rd Militärische Aufnahme (military cartographic survey) of Austria-Hungary. Of course, they were updated, and their contents reflect the land as of the 1910-20s.

Maps are quite accurate, and well detailed. One can observe the structure of settlements at the street level. Although maps display small black rectangles in streets that could be considered as single houses or buildings, this, however, is not a good interpretation. These forms simple refer to the fact, that there are buildings in the street. This way the number of the black rectangles does not match the real number of the buildings in the street.

There are some 50 sheets that cover old Hungary, that is Hungary before 1920. I'm planning to add 5-6 sheets monthly, so that a complete set could be online by late Autumn 2001. Update January 2002: Due to my other duties, the preparation of the material could not be accomplished. The next batch of sections will be available in February 2002.

Access to online maps
Online images are available for subscribers of RadixIndex with either the RadixIndex (Standard) or with the RadixIndex Light plan. Subscription information is available here. Guest visitors will see maps with thick grids on them. Sample images are available at the toolbox.

Some technical details
The maps on original sheets are 368x560 mm in size. They were scanned at 600 dpi. Online, downloadable sections are available in 1000x750 pixel size.

Instead of Greenwich, the 0o of longitude of the mapping system is at Ferro in the Canary Islands. This way, if you would like to get longitude in the modern, Greenwich system, deduct 17 degrees and 40 minutes from the Ferro-system longitude. On the other side, to get a Ferro degree from a Greenwich one, add 17o40' to the Greenwich value.
