The article discusses different types of cadastres used in land management, focusing on the computational cadastre in Hamburg. It explains how numerical, coordinate, and computational cadastres have evolved over time. The numerical cadastre uses field measures or photogrammetry, while the coordinate cadastre stores points in coordinate form for automation. The computational cadastre is most cost-effective for large cities but requires a dense control network for accuracy. Photogrammetric methods are gaining popularity for rural areas due to their economic benefits.
