As a GIS tool, visibility analysis is used in many areas to evaluate both visible and non-visible places. Visibility analysis builds on a digital surface model describing the terrain morphology, including the position and shapes of all objects that can sometimes act as visibility barriers. However, some barriers, for example vegetation, may be perm...

The paper is focused on developing a new approach how automatically process 3D geospatial data for Remcom Wireless InSite. Remcom Wireless InSite is a software tool which provides efficient and accurate predictions of an electromagnetic waves propagation and a communication channel characteristics in complex urban, indoor, rural and mixed path envi...
Chapter
The paper is focused on research in the area of processing LIDAR data with Apache Hadoop. Our team is managing an information system that is able to calculate probability of existence of different objects in space and time. The system works with a lot of different data sources, including large datasets. We may process LIDAR data in the future as we...
Article
The study focuses on the assessment of surface area thermal activity measured by air thermal photography at the significant geotourism locality of Ema coal tailing dumps. Ema has become a geotourism post-mining landmark associated with black coal mining in Ostrava, the third largest city in the Czech Republic. At the same time, Ostrava is the large...
Chapter
Mobile platforms bring possibilities to use distributed services in several users’ environments. One of the conditions of the mobile platform is to transfer as less as possible amount of data via network. When dealing with geodata in mobile environment it is always necessary to use compression algorithms to lower their size. Digital elevation model...
Book
The aim of the conference is to present and discuss new methods, issues and challenges encountered in all parts of the complex process of gradual development and application of digital surface models. This process covers data capture, data generation, storage, model creation, validation, manipulation, utilization and visualization. Each stage requi...
Conference Paper
The paper describes an expert system that helps in a process of a map sheet creation. The expert system is based on ontology that describes basic elements of a map sheet and geodata used for map sheet creation. The paper describes mainly how is the ontology used for building knowledge base of the expert system. The expert system is based on DROOLS...

Guest Editorial Digital surface models for geosciences The Institute of Geonformatics at VSB – Technical University of Ostrava has organized ninth annual Symposium GIS Ostrava 2012, in Ostrava, Czech Republic from 23-25 January 2012. The international part of the symposium followed one main topic – Surface models for geosciences this year. This s...
Article
When dealing with a large set of geodata it is always necessary to use compression algorithms to lower their size. There are several algorithms that can be used for aerial (satellite) photos. The algorithms with a best compression ratio are nowadays based on a wavelet technique. Although digital elevation models (DEM) in a GRID form are a bit diffe...
