Summary
In 2018, Baden-Württemberg is celebrating the bicentenary of the beginning of its official land survey. The ordnance survey in the former Kingdom of Württemberg in 1818–1840 is thereby representative for the establishment of official cadastral and mapping systems, as they developed in every German federal state during the nineteenth century. Whereas the land survey primarily provided a basis of taxation and for extensive topographic maps in the early years, nowadays together with real estate cadastre, it is an institution in Baden-Württemberg which guarantees real estate protection. Furthermore, it is a neutral basis for versatile future-orientated applications. Along with the changing political and social framework, Baden-Württemberg’s surveying authorities have continuously developed and improved organisationally, technically and technologically. Latest measuring techniques and interoperable geodata with official quality are highly demanded for public service tasks in a digital and cross-linked world of tomorrow. Actively working in nationwide and international cooperation networks, Baden-Württemberg has committed itself to promote an infrastructure based on the high-quality geospacial data of land survey and real estate cadastre. In highly dynamic times, the relevance of surveying and geospacial authorities is permanently expanded further, while their digital future is being enforced. The article highlights the genesis, the development and the importance of Baden-Württemberg’s ordnance survey.
