Nurunnabi, A. (author), Teferle, F. N. (author), Lindenbergh, R.C. (author), Li, J. (author), Zlatanova, S. (author)Road surface extraction is crucial for 3D city analysis. Mobile laser scanning (MLS) is the most appropriate data acquisition system for the road environment because of its efficient vehicle-based on-road scanning opportunity. Many methods are available for road pavement, curb and roadside way extraction. Most of them use classical approaches...journal article 2022

Alattas, A.F.M. (author), Kalogianni, E. (author), Alzahrani, Thamer (author), Zlatanova, Sisi (author), van Oosterom, P.J.M. (author)This paper presents in detail the legislation and regulation related to the use and ownership of building complexes with multiple units (apartments, condominiums) in Saudi Arabia for the 3D registration of the legal spaces. The 3D Land Administration Domain Model (LADM)country profile for Saudi Arabia must be able to represent the identified...journal article 2021

Diakité, A. A. (author), Zlatanova, S. (author), Alattas, A.F.M. (author), Li, K. J. (author)Indoor environments differ from outdoor in many aspects. This, added to the limitations faced by other common standards for urban features reinforced the need of setting a dedicated standard for indoor applications. IndoorGML was born in this context to provide the basic concepts, data models, and standard that meet the requirements of indoor...journal article 2020

Zhou, K. (author), Lindenbergh, R.C. (author), Gorte, Ben (author), Zlatanova, S. (author)Change detection is essential to keep 3D city models up-to-date. LiDAR data with high accuracy are used to create 3D city models. However, updating LiDAR data at state or nation level often takes around a decade. Very high resolution (VHR) stereo images, with often yearly updating rate and dense 3D information, provide an option for...journal article 2020

Alattas, A.F.M. (author), van Oosterom, P.J.M. (author), Zlatanova, Sisi (author), Hoeneveld, D. (author), Verbree, E. (author)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....journal article 2020

Scholtenhuis, Léon Olde (author), Vahdatikhaki, Farid (author), Zlatanova, S. (author), Beetz, Jakob (author), Pauwels, Pieter (author)Excavation work takes place almost continually in most cities around the Western hemisphere. Many cities are already full of infrastructures, buried networks, and street furniture, so excavation work is not without any thread to the operator and surrounding environment. Small construction sites, for example, are often constrained by operating...journal article 2019

Liu, Liu (author), Zlatanova, S. (author), Li, Bofeng (author), van Oosterom, P.J.M. (author), Liu, Hua (author), Barton, Jack (author)An indoor logical network qualitatively represents abstract relationships between indoor spaces, and it can be used for path computation. In this paper, we concentrate on the logical network that does not have notions for metrics. Instead, it relies on the semantics and properties of indoor spaces. A navigation path can be computed by...journal article 2019

Díaz-Vilarino, L. (author), González-De Santos, L. (author), Verbree, E. (author), Michailidou, G. (author), Zlatanova, S. (author)Visibility is a common measure to describe the spatial properties of an environment related to the spatial behaviour. Isovists represent the space that can be seen from one observation point, and they are used to analyse the existence of obstacles affecting or blocking intervisibility in an area. Although point clouds depict the as-built...journal article 2018

Den Duijn, X. (author), Agugiaro, G. (author), Zlatanova, S. (author)Precise and comprehensive knowledge about 3D urban space is required for simulation and analysis in the fields of urban and environmental planning, city administration and disaster management. In order to facilitate these applications, geo-information about functional, semantic, and topographic aspects of urban features, their mutual...journal article 2018

Alattas, A.F.M. (author), van Oosterom, P.J.M. (author), Zlatanova, S. (author), Hoeneveld, D. (author), Verbree, E. (author)During an incident, many people that are located in indoor environments require to follow emergency evacuation procedures. The ‘emergency evacuation’ term has been defined as ‘a critical movement of people from a dangerous area due to the risk or an incident of a tragic event’ (Bonabeau, 2002). An emergency evacuation could be needed in a...journal article 2018

Diakite, A.A. (author), Zlatanova, S. (author)As we realize that we spend most of our time in increasingly complex indoor environments, applications to assist indoor activities (e.g. guidance) have gained a lot of attention in the recent years. The advances in ubiquitous computing made possible the development of several spatial models intending to support context-aware and fine-grained...journal article 2018

Staats, Bart (author), Diakite, A.A. (author), Voûte, R.L. (author), Zlatanova, S. (author)Generation of indoor networks for navigation will normally be done out of standard floor plans that are only 2D and is more often manual than automatic. These floor plans are drawn at a specific time and do not correspond to the reality, moreover some of those buildings were built already differently than designed. Then in due course the...journal article 2018

Wang, Z. (author), Zlatanova, S. (author), van Oosterom, P.J.M. (author)In this paper, we study path planning for first responders in the presence of uncertain moving obstacles. To support the path planning, in our research we use hazard simulation to provide the predicted information of moving obstacles. A major problem in using hazard simulation is that the simulation results may involve uncertainty due to...journal article 2017

(author), Chatzinikolaou, Efstathia (author), Lemmen, Christiaan (author), Li, Ki Joune (author)The aim of this research is to investigate the combined use of IndoorGML and the Land Administration Domain Model (LADM) to define the accessibility of the indoor spaces based on the ownership and/or the functional right for use. The users of the indoor spaces create a relationship with the space depending on the type of the building and the...journal article 2017

Wang, Z. (author), Steenbruggen, John (author), Zlatanova, S. (author)This paper investigates the integration of traffic information (TI) into the routing in the presence of moving obstacles. When traffic accidents occur, the incidents could generate different kinds of hazards (e.g., toxic plumes), which make certain parts of the road network inaccessible. On the other hand, the first responders, who are...journal article 2017

Diakite, A.A. (author), Zlatanova, S. (author)For several decades, indoor navigation has been exclusively investigated in a 2D perspective, based on floor plans, projection and other 2D representations of buildings. Nevertheless, 3D representations are closer to our reality and offer a more intuitive description of the space configuration. Thanks to recent advances in 3D modelling, 3D...journal article 2016

Zlatanova, S. (author), Isikdag, Umit (author)In the construction industry, business relationships are often short-term and one-off. There are many unique processes and activities. The resulting complexity and fragmentation may obstruct quick and effective exchange and integration of information and thus hamper project progress. Building Information Modelling (BIM) aims at preventing...journal article 2016

Gorte, B.G.H. (author), Zlatanova, S. (author)The paper presents a very straightforward and effective algorithm to convert a space partitioning, made up of polyhedral objects, into a 3D block of voxels, which is fully occupied, i.e. in which every voxel has a value. In addition to walls, floors, etc. there are 'air' voxels, which in turn may be distinguished as indoor and outdoor air....journal article 2016
