Requirements and Opportunities for Web-Based 3D Visualization and Dissemination of Property Valuation Information

The timely and effective dissemination of property values is an essential part of a transparent and efficient property valuation system as property values are required in several land administration processes, such as land acquisition, taxation, transaction, consolidation, readjustment and transformation. In the last decade, a web-based data...

LADM-IndoorGML for exploring user movements in evacuation exercise

The users' movements in the indoor environments differ based on the condition of the environments. During an indoor emergency, an efficient evacuation is required to help the users to move to the safe areas. Many types of incidents could impact the movements of users and this requires studying the behavior of the people during the evacuation....

Exploring and assessing STDM and LADM for gender equitable land administration

International laws and frameworks such as the 2030 Agenda for Sustainable Development with its defined Sustainable Development Goals (SDGs), together with the Voluntary guidelines on the responsible governance of tenure of land, fisheries and forests in the context of national food security (VGGTs) are key global cornerstones in the protection...

LADM Refined Survey Model

First Edition of the Land Administration Domain Model (LADM) has three packages related to: Parties (people and organisations); Basic Administrative Units, Rights, Responsibilities, and Restrictions (of ownership rights); spatial units (parcels, and the legal space of buildings and utility networks) with a sub package for Surveying and...

A Suggested Terminology for Point-Like Entities in a Bi-Temporal Representation of 2D and 3D Land Administration Data

The prime purpose of Cadastral data – whether in the form of maps, survey plans or notes, or a digital database is the definitive demarcation of the extent of properties – and can be seen primarily as a decision support facility (“Can a structure be built here?”, “Where can I build a fence?”, “Should I buy this property”?). There are, however...

A Matrix-Based Structure for Vario-Scale Vector Representation over a Wide Range of Map Scales: The Case of River Network Data

The representation of vector data at variable scales has been widely applied in geographic information systems and map-based services. When the scale changes across a wide range, a complex generalization that involves multiple operations is required to transform the data. To present such complex generalization, we proposed a matrix model to...

Further standardisation in Land Administration
