Description

The dataset presents a reconstruction of mid-19th-century building structure locations in former Galicia and Austrian Silesia (parts of the Habsburg Monarchy), located in present-day Czechia, Poland and Ukraine and covering more than 80 000 km2. Our reconstruction was based on a homogeneous series of detailed Second Military Survey maps (1:28,800), which were the result of cadastral mapping (1:2,880) generalization. The dataset consists of two kinds of building structures based on the original map legend – residential and outbuildings (mainly farm-related buildings), and contains more than 1.3 million objects. The dataset’s accuracy was assessed quantitatively and qualitatively using independent data sources and may serve as an important input in studying long-term socio-economic processes and human-environmental interactions or as a valuable reference for continental settlement reconstructions. Acknowledgments This research was funded by the Ministry of Science and Higher Education, Republic of Poland under the frame of “National Programme for the Development of Humanities” 2015–2020, as a part of the GASID project (Galicia and Austrian Silesia Interactive Database 1857–1910, 1aH 15 0324 83).

Steps to reproduce

The reconstruction was based on a homogeneous set of Second Military Survey maps, which were acquired from the War Archive in Vienna in the form of scanned .tif files (at 300 DPI). The maps for Austrian Silesia (42 map sheets) were published in the period 1837–1841 and those for Galicia (412 map sheets) were published in the period 1861–1864. The maps show two main categories of buildings in different colours – red (ger. Wohngebäude), indicating mainly residential buildings and black (ger. Wirtschaftsgebäude), including farm or agriculture-related buildings. We used a semiautomatic, colour-based method to acquire residential buildings and manual vectorization to acquire the farm buildings. Each map sheet was then verified manually to eliminate commissions and omissions. Finally, the data were subject to several accuracy assessments. We assessed the acquisition accuracy and referred the data with the census data at different administrative levels. Additionally, we verified the number of buildings with the textual information presented on the original map sheets in the form of building number summaries and used auxiliary data such as cadastral maps as needed. Finally, we added the attributes presented below: type - the type of the building (1 - residential, 2 - farm-related) Year 1, Year 2 - map sheet production period comment - if map sheet production dates were not specified, we analysed the dates of neighbouring sheets and added it here as the most probable period
