3D pgRouting and visualization in Cesium JS using the integrated model of LADM and IndoorGML

A web-based application has been developed, exploiting the integrated model of LADM andIndoorGML to provide indoor navigation based on the user's access rights in an educationalbuilding. Different types of users (students, teachers, visitors, etc.) have different access rights,which also depend on the exact time (e.g. inside or outside office...

2D Country Profile for the Kingdom of Saudi Arabia Based on LADM

In our earlier study, the land administration system in Saudi Arabia has been analyzed to develop the initial country profile based on LADM. The testing and validation of the initial country profile have shown that only the necessary information has been covered, and there is much critical information related to the property registration still...

Initial Country Profile of the Kingdom of Saudi Arabia based on LADM

This paper proposes an initial LADM country profile of Saudi Arabia. The model aims to build a better communication system between all the stockholders to secure the land registration. The initial development of the spatial and non-spatial classes are have been based on the regulation of Saudi Arabia. For the development of the LADM profile for...

Developing a database for the LADM-IndoorGML model

This paper presents the development of database for the conceptual model of LADM-IndoorGML. The aim of this work is to investigate all issues that related to generating the database and visualizing the content of the database. Based on the result of the transformation from conceptual model to the technical model that has been proposed by ...

Deriving the Technical Model for the Indoor Navigation Prototype based on the Integration of IndoorGML and LADM Conceptual Model

This paper shows the conversion of LADM-IndoorGML conceptual model to technical model. The aim of this research is assessing the conceptual model and discovering the possibilities and the shortcomings of the conceptual model via the conversion to technical model. There are three steps to convert the conceptual model:<br/>- Prepare the LADM...

3D Cadastres Best Practices, Chapter 4: 3D Spatial DBMS for 3D Cadastres

Subdivision of land parcels in the vertical space has made it necessary for cadastral jurisdictions to manage cadastral objects both in 2D as well as 3D. Modern sensor and hardware capabilities for capture and utilisation of large point clouds is one of the major drivers to consider Spatial Database Management Systems (SDBMS) in 3D and...

3D Cadastres Best Practices, Chapter 3: 3D Cadastral Information Modelling

In this chapter we address various aspects of 3D Cadastral Information Modelling. Of course, this is closely related to the legal framework and initial registration as presented in the first two chapters. Cadastral data models, such as the Land Administration Domain Model, which include 3D support, have been developed for legal information...

Improved and more complete conceptual model for the revision of IndoorGML

With the increasing number of indoor navigation applications, it is essential to have clear and complete conceptual model (in the form of UML class diagram) for IndoorGML. The current version of IndoorGML standard has an incomplete class diagram (incomplete w.r.t. attributes, of which some are appearing in the XML/GML schema), and that...

Indoor Abstract Spaces: Linking IndoorGML and LADM

In this paper we investigate the possible synergy between two different but related standards: OGC’s IndoorGML and ISO TC211’s LADM. Both (can) deal with 3D spaces with properties, constraints and associations attached and both can operate with abstract notations of space. But there are also differences, e.g. LADM is a conceptual model, while...

Resolution in photovoltaic potential computation

In this paper, an analysis of the effect of the various types of resolution involved in photovoltaic potential computation is presented. To calculate solar energy incident on a surface, shadow from surrounding buildings has been considered. The incident energy on a surface has been calculated taking the orientation, tilt and position into...

LANDM and IndoorGML for support of Indoor Space identification

Guidance and security in large public buildings such as airports, museums and shopping malls requires much more information that traditional 2D methods offer. Therefore 3D semantically-reach models have been actively investigated with the aim to gather knowledge about availability and accessibility of spaces. Spaces can be unavailable to...
