Implementation of OGC SensorThings API standard for the integration of dynamic sensor data in a 3D urban digital twin

Urban areas are home to over half of the global population and consume significant natural resources, necessitating effective city management for urban resilience and sustainability. Resilient cities are better prepared to face challenges, from natural disasters to economic downturns, and adapt to climate change, resource scarcity, and...

Modeling data dissemination processes as part of the future LADM development

Land administration (LA) is dynamic, and it cannot be understood, built or improved unless the processes associated with it are understood. One of the core standards in the domain of LA, namely ISO 19152 Land Administration Domain Model (LADM) provides conceptual data models for land administration systems (LASs). However, it does not cover all...

Land Administration Domain Model OGC Standards Working Group

In February 2019 the OGC White Paper on Land Administration is published. This White Paper provides an overview of the land administration domain and relevant developments. It also proposes necessary actions for the design and development of an implementation standards. The document includes an overview of needs and requirements as earlier...

An OGC 3D tiling technique based user-interactive platform for digital twins in a virtual reality environment

There has been an ever increasing focus on the development of smart cities, both by big corporate in the field of Information Communication and Technology as well as respective governments responsible for these cities worldwide. This in combination with the influx of easily accessible data owing to cheaper and efficient sensors has risen to the...

Integrated modeling of utility networks in the urban environment

In recent years, there has been an exponential growth in the need for 3D spatial information, particularly 3D models representing the geographic information of the urban environment. The existence of a comprehensive integrated 3D model representing the condition of the underground utility networks in accordance with the above-ground city objects...

Increasing FAIRness by sustainable modelling of interactions of parties with land administration systems

In recent years, mobile and web applications are being used extensively and availability of data, including geospatial data has increased dramatically. With the outbreak of Covid-19 this was emphasised even more. The emphasis from large IT systems has shifted towards modular service-oriented systems. This allows easier upgrading and adding of...

Investigating the requirements for the ISO 19152 LADM survey encodings

The ISO 19152:2012 Land Administration Domain Model (LADM), focuses on standardised modelling of land information at the conceptual level, and together with LADM’s three main packages, it has a dedicated sub package for Spatial and Surveying representation. The first edition of the standard provides multiple spatial representations, and a rather...

Design and Evaluate the OGC Web Services Architecture of a Geohazard analysis tool

Open standards like Open Geospatial Consortium (OGC) standards can be used to improve interoperability and re-usability among geospatial tools, datasets and services across the web. Today more than six thousands commercial and non commercial implementations of the OGC Web Services (OWS) are available, and more and more Geographical Information...

Code list management supported through a controlled domain vocabulary

Standards like the ISO 19152:2012 Land Administration Domain Model (LADM) basically specifies classes and the relations among them. However, this methodology cannot catch the richness of variations of the domain, and therefore code lists are introduced as a supplement. In fact, the LADM mentions a number of code lists for each of the packages of...

Joint ISO/TC211 and OGC Revision of the LADM: Valuation Information, Spatial Planning Information, SDG Land Indicators, Refined Survey Model, Links to BIM, Support of LA Processes, Technical Encodings, and Much More on Their Way!

ISO standards, which are actually being applied, are subject to periodic revision, typically in a 6 to 10-year cycle. A UN-GGIM Meeting of the Expert Group on Land Administration and Management was held on 14-15 March 2017, in Delft and the main conclusion was that the revision of LADM was indeed needed in order to provide better tools to...

International Code List Management – The Case of Land Administration

Standardization reduces technical barriers to trade and foster dissemination of innovations. Within the domain of information technology, standardization enhances semantic interoperability of systems and services. In order to achieve the potential of standardization, IT solutions must be localized to adapt to local needs. To reduce localization...

Towards interoperable standards for 1D time series data within the water sector

Water management is becoming increasingly important in the world. Population growth, climate change, and increasing demands placed on infrastructure call for a smart and standardized approach. The data needs to stay at the source and sharing information in a more efficient way is becoming increasingly important. To make this possible in the...

Advancing Open 3D Modelling Standards in National Spatial Information Policy

Individuals and organisations around the world - facing extraordinary challenges and new opportunities - are together engaged in numerous projects, involving natural and built environments. Spatial information policy is at the heart of these projects. The information technologies available enable individuals to observe, measure, describe, map...

A cityGML 3D geodatabase for building's energy efficiency

This paper illustrates the results of a research focused on the development of a multi-scale geodatabase designed to store the data needed to measure the energy buildings performance of buildings to be used for the planning activities of local administrations. Due to the great complexity of the application domain, the proposed data model has...

Why new tools were developed for the 'GeoPortalNetwork: Liberty United" project

As part of the national innovation co-funding scheme “Space for Geo-information” the project “GeoPortal Network: Liberty United” ran from late 2005 till the end of 2008. Purpose of the project was to promote access to geo-spatial information via web services. To achieve this goal, a network of geo-portals that is governed by a minimum set of...
