National Mapping, Cadastral and Land Registration Authorities

National Mapping, Cadastral, and Land Registration Authorities (NMCAs) are governmental organizations responsible for producing topographic maps and geographic information for a country. They maintain cadastral information, which includes records of land ownership, dimensions, and value, often evolving into multipurpose land information systems. These authorities play a crucial role in a nation's spatial data infrastructure (SDI) and are increasingly using GIS technology to integrate cadastral data with other information themes for sustainable development and land management. EuroGeographics is an example of an international non-profit organization representing European NMCAs, collaborating with entities like the European Environment Agency (EEA) to enhance access to geospatial datasets within programs like Copernicus.
