Map indexes of the Second Military Survey in 1:28,800 scale for Galicia and Austrian Silesia, mid-19th century.

The data set presents the map indexes of the Second Military Survey in 1:28,800 scale for Galicia and Austrian Silesia, two provinces of the Austrian Monarchy. Currently, Galicia belongs to Ukraine and Poland, and Austrian Silesia to the Czech Republic and Poland. The indexes, apart from the approximate geographical range, contain information about the authors and the years in which individual sheets were produced. The authors of the maps are distinguished as directors, surveyors and drafters, description writers, and reambulators. For each author, the name of the military unit to which he belonged is given. This is a unique set of data obtained from the map frames of 455 sheets held by the War Archives in Vienna.
The Second Austrian Military Survey in 1:28,800 scale was made for the province of Galicia in 1861-1864 and for Austrian Silesia in 1838-1841. In Galicia, the work on 413 sheets was led by thirteen cartographers, and the content and descriptions were prepared by 106 cartographic technicians. On the 42 sheets of Silesia, two directors and eleven technicians were recorded. The military cartographers who prepared the survey of each province belonged to 71 different multinational units of the army of the Austrian Monarchy.
These data can be useful for geographers and historians, especially for those researching the history of cartography. Knowing the diverse authorship of the map sheets is helpful in understanding the consistency of the data on maps and assessing their quality. This may help reduce the uncertainty of using historical data from these maps for a variety of long-term studies of nature and socio-economic studies.

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).

本数据集展示了奥地利帝国时期加利西亚及奥地利西里西亚两省的第二次军事测绘图例，比例尺为1:28,800。目前，加利西亚隶属于乌克兰及波兰，而奥地利西里西亚则属于捷克共和国及波兰。图例不仅包含了大致的地理范围信息，还记录了各张图版的作者及其制作年份。地图的作者被区分为总监、测绘员、制图员、描述撰写者和重绘者。对于每位作者，还提供了其所归属的军事单位名称。这是一套独特的从维也纳战争档案馆所保存的455张图版中获取的数据集。第二次奥地利军事测绘（比例尺1:28,800）于1861-1864年间针对加利西亚省进行，1838-1841年间针对奥地利西里西亚省进行。在加利西亚，413张图版的工作由十三位制图员领导，内容与描述由106位制图技术人员准备。西里西亚的42张图版记录了两位总监和十一位技术人员。各省份测绘工作的制图员隶属于奥地利的71个不同国籍的军队单位。这些数据对于地理学家和历史学家尤其有用，特别是对于研究制图史的研究者。了解地图图版的多元作者背景有助于理解地图数据的连贯性及其质量评估，这或许有助于降低使用这些地图的历史数据在自然及社会经济长期研究中的不确定性。
