Nowadays, 75 percent of the world population does not have access to formal land administration systems, which are able to register and safeguard their land rights. There is an urgent need for sustainable and affordable systems, which are able to secure land rights for all people, in all places, at all time. The cadastral map, which shows land parcels and their boundaries, in one of the most important components of land administration. This research is proposing to construct a cadastral map, according to the general boundary concept, with the use of airborne laser scanning. For this, a workflow is developed. General boundaries are coinciding with topographic features, which can be detected in point clouds. The general boundaries can be used to determine land parcels and subsequently land rights of people can be linked to the land parcels. Attention is paid to topographic features which often serve as general boundaries and to a suitable point cloud density for detecting particular topographic features. This MSc thesis has demonstrated that airborne laser scanning is suitable for deriving a large share of topographic features, which may serve as general boundary. However, it is necessary to know on forehand, which topographic features in a particular area of country are general boundaries. If this is known, the required point cloud density and the type of analysis can be determined.
