Zlatanova, S. (author), Nourian Ghadikolaee, P. (author), Goncalves, R. (author), Vo, A.V. (author)Three-dimensional (3D) raster are simple representations, which have long been used for modelling continuous phenomena such as geological and medical objects. However, they can result in large data sets when high resolution is used, which poses challenges to algorithms for vector-to-raster conversion and data storage. This paper presents a...conference paper 2016

Demir Ozbek, E. (author), Zlatanova, S. (author), Ates Aydar, S. (author), Yomralioglu, T. (author)A conceptual approach is proposed to define 3D geo-information requirement for different types of disasters. This approach includes components such as Disaster Type-Sector-Actor-Process-Activity-Task-Data. According to disaster types processes, activities, tasks, sectors, and responsible and operational actors are derived. Based on the tasks,...conference paper 2016

Makri, A. (author), Zlatanova, S. (author), Verbree, E. (author)This work presents an approach to enhance navigation in indoor environments based on a landmark concept. It has already been proved by empirical research that by using landmarks the wayfinding task can be significantly simplified. Navigation based on landmarks relies on the presence of landmarks at each point along a route where wayfinders might...conference paper 2015

Xiong, Q. (author), Zhu, Q. (author), Zlatanova, S. (author), Du, Z. (author), Zhang, Y. (author), Zeng, L. (author)Indoor navigation is increasingly widespread in complex indoor environments, and indoor path planning is the most important part of indoor navigation. Path planning generally refers to finding the most suitable path connecting two locations, while avoiding collision with obstacles. However, it is a fundamental problem, especially for 3D complex...conference paper 2015

Liu, L. (author), Xu, W. (author), Penard, W. (author), Zlatanova, S. (author)In this paper, we leverage spatial model to process indoor localization results and then improve the track consisting of measured locations. We elaborate different parts of spatial model such as geometry, topology and semantics, and then present how they contribute to the processing of indoor tracks. The initial results of our experiment reveal...conference paper 2015

Isikdag, U. (author), Horhammer, M. (author), Zlatanova, S. (author), Kathmann, R. (author), Van Oosterom, P.J.M. (author)Valuation of the properties is known as real estate appraisal, property valuation or land valuation and is a process which focuses on determining the value of a building or a land lot. The valuation of each real estate is required prior to any transaction as every property is unique in terms of shape, volume, location, orientation, quality and...conference paper 2015
