The cadastral systems used in each country and region have developed through the centuries to their current form. We cannot assume that the current situation will remain the same from this point to the future. There are signs in recent studies and development projects throughout the world that those cadastral systems which are traditionally seen as well-functioning also need to be renewed as society changes at a rapid pace. This study is set up to analyze the future needs of a cadastral system and registers related to it in Finland. The objective of the study is to reveal future themes affecting the operational environment of the cadastral system by using research methods provided by futurology. The method used in this study is called environmental scanning and it consists of three phases: collecting events, recognizing phenomena and combining the phenomena as themes. The study analyses 352 literature sources and reveals 14 different future themes in the operational environment of the cadastral system, which are economic pressure, demographic changes, development of technology, transparent society, safety, environmental values, globalization, digitalization, know-how, quality, political change, soft values, public-private partnership and crowd sourcing. The future themes, their possible relations between each other and their significance for the cadastral system are analyzed by using the concepts of megatrends, trends, wild cards, driving forces and weak signals and reflecting the results to research made in the field of land management internationally. The results can be used when renewing a cadastral system, in order to consider possible future themes that may affect the system. Detecting and recognizing the future themes provides an opportunity to react and change the course of action in order to adapt to the future. The results are not only usable in the Finnish context, but can also be applied in other countries development of their cadastre and as part of environmental scanning.
