Old cadastral maps represent a historical reference dataset for long-term land-use reconstructions. This study presents identification of inconsistencies in the nineteenth century Franziscean cadastre, one of the largest sets of old cadastral maps worldwide, by comparing three versions of the maps and written documents created in the same period. We identified all parcels and their land-use in the four sub-sources in six study areas. The overall share of inconsistencies among 5 771 identified parcels is 7.4%, with the biggest share of inconsistency in agroforestry and forestry classes. The most frequent inconsistencies are of ‘Not differentiable land use’ (n = 212) and ‘Different land-use’ categories across the sub-sources (n = 113). We conclude that the frequency of uncertainties in old cadastral maps may limit the validity of historical land-use reconstructions, affecting the eventual restoration and management efforts based on such data. We provide a summary for the use of Franziscean cadastre.

旧的地籍图代表了长期土地使用重建的历史参考数据集。本研究通过比较地图的三个版本和同期创建的书面文件，鉴定了19世纪的Franziscean地籍中的不一致之处，这是世界上最大的旧地籍地图集之一。我们在六个研究区域的四个子来源中确定了所有宗地及其土地使用。在5 771个已确定的宗地中，不一致的总体比例为7.4％，其中农林业和林业类别中不一致的比例最大。最常见的不一致是子源之间的“不可区分的土地使用”（n = 212）和“土地不同使用”类别（n = 113）。我们得出的结论是，旧地籍地图中不确定性的发生频率可能​​会限制历史土地用途重建的有效性，从而影响基于此类数据的最终恢复和管理工作。我们提供了Franziscean地籍使用的摘要。
