Current software solutions for solar-radiation modeling in 3D focus on the urban environment. Most of the published tools do not implement methods to consider complex objects, such as urban greenery in their models or they expect a rather complex 3D mesh to represent such objects. Their use in an environment that is difficult to represent geometric...

Solar radiation significantly affects many processes on Earth. In situ measurements are demanding and require a dense network of sensors. A suitable alternative solution could be the modelling of potential solar radiation based on a digital elevation model (DEM) in geographic information systems. The key issue of this study is to determine the infl...

Plant traits are an expression of strategic tradeoffs in plant performance that determine variation in allocation of finite resources to alternate physiological functions. Climate factors interact with plant traits to mediate tree survival. This study investigated survival dynamics in Norway spruce (Picea abies) in relation to tree-level morphologi...

Machine learning algorithms (MLAs) are used to solve complex non-linear and high-dimensional problems. The objective of this study was to identify the MLA that generates an accurate spatial distribution model of bark beetle (Ips typographus L.) infestation spots. We first evaluated the performance of 2 linear (logistic regression, linear discrimina...

The use of LED lights in smart street lighting to save energy is efficient and very common in many developed cities. However, such a system results in higher initial costs, which may discourage smaller towns and villages from its purchasing. This paper therefore deals with the design and development of a smart street lighting control system for sma...

The European spruce bark beetle Ips typographus L. causes significant economic losses in managed coniferous forests in Central and Northern Europe. New infestations either occur in previously undisturbed forest stands (i.e., spot initiation) or depend on proximity to previous years' infestations (i.e., spot spreading). Early identification of newly...
Conference Paper
There are currently numerous systems used in online testing and examination. Some of them focus on a high complexity and require complicated control; on the other hand, simple examination systems do not always meet specific user requirements. For example, online testing in the domain of geosciences requires the use of specific figures and ensure th...
Conference Paper
Multiple criteria decision making usually means selection of the best objects or their parameters which best meet conditions or criteria. Human decision making often involves also uncertain and vague criteria. The terms as a short distance, a high building or long time are commonly used in human speech. Nevertheless, it is not necessary to describe...
Conference Paper
The paper deals with issue of computation of the sunrays penetration through point cloud data with considering the geometrical and astronomical principles in calculating the Sun position relative to points of the objects on the Earth surface. Input data are represented by point cloud obtained by the method of terrestrial laser scanning and they exp...

Updating and creation of the navigation map in the Map Creator software environment. Abstract: Regular updating of maps is necessary to use them for navigation. HERE is a company which provides map for navigation and enables people around the world not only use but also to map the places where they live. Map Creator is the map editing tool used to...
Article
Full-text available
When combining spatial data from various sources, it is often important to determine similarity or identity of spatial objects. Besides the differences in geometry, representations of spatial objects are inevitably more or less uncertain. Fuzzy set theory can be used to address both modelling of the spatial objects uncertainty and determining the i...

As a complex of buildings, the Faculty of Natural Sciences of the Comenius University in Bratislava tends to be difficult to navigate in spite of its size. An indoor navigation application could potentially save a lot of time and frustration. There are currently numerous technologies used in indoor navigation systems. Some of them focus on a high d...
Chapter
Landslides in Slovakia are followed by great economic loss and threat to human life. Therefore, implementation of landslides susceptibility models is essential in urban planning. The main purpose of this study is to investigate the possible applicability of Support Vector Machines (SVMs) in landslides susceptibility prediction. We have built a clas...
Chapter
The basic precondition for effective management and protection of a forest is a concept built on modern methods of collection, processing, analysis and publication of spatial data about forest coverage, as well as its health status. This paper provides a structural concept for integration of heterogeneous data in the support of the forest protectio...

Full-text available
Spatial data integration is the process of combining heterogeneous data to make them compatible, maintain data accuracy and actuality, minimize redundancy, and avoid data conflicts. Identification of spatial objects is one of the most important tasks in spatial data integration. In this paper, we propose to use determination of the similarity measu...

Flood protection is one of several disciplines where geospatial data is very important and is a crucial component. Its management, processing and sharing form the foundation for their efficient use; therefore, special attention is required in the development of effective, precise, standardized, and interoperable models for the discovery and publish...
Article
Spatial data is very often uncertain. The quality of spatial data is also very variable. The functions and operations which are performed with the data in information systems and object-relational database systems are mostly implemented by the use of crisp rules and criteria based only on Boolean logic. This classical approach often leads to a loss...

Archaeological predictive modelling unites spatial analysis and the methods of geographic information systems (GIS) up with spatial (landscape) archaeology. Archaeological predictive models (APM) are used in several academic and practical applications to model and verify archaeological hypotheses about the relationship between humans and the landsc...

This paper deals with uncertainty modeling in spatial object-relational databases by the use of Structured Query Language (SQL). The fundamental principles of uncertainty modeling by fuzzy sets are applied in the area of geographic information systems (GIS) and spatial databases. A spatial database system includes types of spatial data and implemen...
Conference Paper
The development of urban agglomerations and human settlements brings increasing a pressure to effective protection and preservation of cultural and historical heritage. Geographic information systems could play here an important role, on the one hand to help register and manage approachable information about existing cultural and historical heri...

The initiative to establish Spatial Data Infrastructure (SDI) within the Geodetic and Cadastral domain at the Slovak University of Technology aims to implement all principles defined by INSPIRE directive. INSPIRE may be taken into account either as a legal act to force member states to follow its paragraphs or as a " best-practices " in establishin...

Station velocities resulting from permanent or epoch GPS observations could be transformed to the parameters of surface deformations under the assumption that the examined territory is a continuous environment. The input geometric information consists of irregularly distributed site velocities expressed in geocentric Cartesian coordinate system. Su...

Project
The expected contribution is mainly in the modeling of 3D objects considering their uncertainty, the creation of spatial models with appropriate level of detail, spatial objects identification based on similarity measures and aggregation of their spatial and thematic properties. The application field of geomodeling within the project is the protection of cultural, historical and natural heritage. The practical contribution will be the facilitation of the spatial data usage by end users by correct mathematical processing and appropriate visualization methods of these datasets.
Project
The project is focused on 3D modeling of solar radiation on tree vegetation represented by a 3D point cloud acquired by laser scanning. The outcome of the project will be a modified v.sun solar radiation model implemented in the open-source GRASS GIS. The project results will be used in the prediction modeling, e.g. in research of occurence of spruce beetle or detailed microclimate analyses in built-up areas.
