Alattas, A.F.M. (author), van Oosterom, P.J.M. (author), Zlatanova, S. (author)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...conference paper 2019

Alattas, A.F.M. (author), van Oosterom, P.J.M. (author), Zlatanova, S. (author)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...conference paper 2018

Janecka, Karel (author), Karki, Sudarshan (author), van Oosterom, P.J.M. (author), Zlatanova, S. (author), Kalantari, Mohsen (author), Ghawana, Tarun (author)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...conference paper 2018

(author), Kalantari, Mohsen (author)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...conference paper 2018

Alattas, A.F.M. (author), Zlatanova, S. (author), van Oosterom, P.J.M. (author), Li, Ki-Joune (author)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...conference paper 2018

Diakite, A.A. (author), Zlatanova, S. (author), Li, Ki-Joune (author)Boosted by the dynamic urbanization of cities, indoor environments are getting more and more complex in order to be able to host people properly. While most of our time is spent inside buildings, the need of GIS tools to assist our daily activities that can become tedious, such as indoor navigation or facility management, became more and more...conference paper 2017

Díaz-Vilarino, L. (author), Verbree, E. (author), Zlatanova, S. (author), Diakite, A.A. (author)Updated and detailed indoor models are being increasingly demanded for various applications such as emergency management or navigational assistance. The consolidation of new portable and mobile acquisition systems has led to a higher availability of 3D point cloud data from indoors. In this work, we explore the combined use of point clouds...conference paper 2017

Staats, B.R. (author), Diakite, A.A. (author), Voûte, R.L. (author), Zlatanova, S. (author)Automatic generation of indoor navigable models is mostly based on 2D floor plans. However, in many cases the floor plans are out of date. Buildings are not always built according to their blue prints, interiors might change after a few years because of modified walls and doors, and furniture may be repositioned to the user's preferences....conference paper 2017

Yan, J. (author), Grasso, N. (author), Zlatanova, S. (author), Braggaar, R.C. (author), Marx, D.B. (author)Three-dimensional modelling plays a vital role in indoor 3D tracking, navigation, guidance and emergency evacuation. Reconstruction of indoor 3D models is still problematic, in part, because indoor spaces provide challenges less-documented than their outdoor counterparts. Challenges include obstacles curtailing image and point cloud capture,...conference paper 2017

Liu, L. (author), Zlatanova, S. (author), Zhu, Q. (author), Li, K. (author)This paper introduces and compares two types of GML-based data standards for indoor location-based services, i.e., iIndoorGML and iIndoorLocationGML. By elaborating the advantages of the both standards and their data models, we conclude that the two data standards are complementary to each other. A jointed data model is presented to show the...conference paper 2017

Xu, Man (author), Wei, S. (author), Zlatanova, S. (author), Zhang, Ruiju (author)At present, 87 % of people's activities are in indoor environment; indoor navigation has become a research issue. As the building structures for people's daily life are more and more complex, many obstacles influence humans' moving. Therefore it is essential to provide an accurate and efficient indoor path planning. Nowadays there are many...conference paper 2017

Rodenberg, OBPM (author), Verbree, E. (author), Zlatanova, S. (author)There is a growing demand of 3D indoor pathfinding applications. Researched in the field of robotics during the last decades of the 20th century, these methods focussed on 2D navigation. Nowadays we would like to have the ability to help people navigate inside buildings or send a drone inside a building when this is too dangerous for people....conference paper 2016

Zlatanova, S. (author), Li, Ki-Joune (author), Lemmen, Christiaan (author), van Oosterom, P.J.M. (author)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...conference paper 2016
