AI4SmallFarms: A Dataset for Crop Field Delineation in Southeast Asian Smallholder Farms

Agricultural field polygons within smallholder farming systems are essential to facilitate the collection of geo-spatial data useful for farmers, managers, and policymakers. However, the limited availability of training labels poses a challenge in developing supervised methods to accurately delineate field boundaries using Earth observation ...

Towards Investigation of Integrating LADM, BIM, and CityGML of 3D Condominium Rights for Cadastral Purposes: The Case of Turkish Cadastral System

Four basic concepts form the basis of a modern land management system: Land Tenure, Land Value, Land Use, and Land Development. Cadastral studies are seen as the cornerstone of these four basic concepts. Especially, complex buildings located underground and above ground form the basis of 3D cadastral studies. In addition, international research...

Integration of LADM and CityGML for 3D Cadastre of Turkey

Representation of Right, Restriction, and Responsibility (RRR) in the 2D cadastral system falls short due to rapid urbanization causing complex infrastructures. Turkish cadastre, as in many other countries, faces difficulties in the daily recording of property transactions such as sales, donations among others. Therefore, it is highly...

3D Cadastre in the Case of Engineering Objects, such as Bridges and Road Viaducts

At present, the implementation of cadastral registration of transport investments (such as railway lines on bridges and on viaducts, roads on viaducts, etc.) is performed in the so-called "layer" system. This means that many objects are constructed at different levels (layers) within the space of a given parcel. Several parties may be interested...

Ontwikkelingen en trends van de FIG Working Week 2020 - Subthema 1: Smart Surveyors

Snelle stedelijke groei, slimme energievoorziening, schonere mobiliteit en landrechten voor iedereen zijn uitdagingen die een innovatieve geomatics-aanpak vereisen. Sensortechnologieën, ruimtelijke gegevensverwerkingsmethoden en aanverwante benaderingen komen steeds meer en beter beschikbaar. De vraag is echter hoe ze te gebruiken en te...

Remote Sensing for Land Administration

Land administration constitutes the socio-technical systems that govern land tenure, use, value and development within a jurisdiction. The land parcel is the fundamental unit of analysis. Each parcel has identifiable boundaries, associated rights, and linked parties. Spatial information is fundamental. It represents the boundaries between land...

Challenges for Updating 3D Cadastral Objects using LiDAR and Image-based Point Clouds

Nowadays due to the increasing complex and multifunctional building environment in the urban areas it is required an accurate geometry and proper legal registration of the cadastral objects including third dimension and time aspect. 2D land-parcel data seems insufficient to address the variety of problems in high density residential areas. This...
