The fast developments in the information technology reflects also on the GIS community and new opportunities give new challenges to the research and development groups. As a result of these developments, 3D data can already be processed efficiently and better methods are being explored increasingly. At the same time, the Internet has matured in many senses since it was first publicized and it i...
[1] Observations from the US Department of Energy’s Atmospheric Radiation Measurement (ARM) program are used to evaluate the ability of the NASA GISS ModelE global climate model in reproducing observed interactions between aerosols and clouds. Included in the evaluation are comparisons of basic meteorology and aerosol properties, droplet activation, effective radius parameterizations, and surfa...
Identifying the main byproducts of SF6 decomposition proves to be an effective strategy for determining nature and severity internal discharge faults in gas-insulated switchgears (GISs). In this research, it was suggested utilize coordination polymer Zr-MOF-808 as a sensor decomposition. This study examined adsorption its products (CF4, CS2, SO2, SO2F2, SOF2) on Zr-MOF-808, utilizing Gaussian16...
The paper describes environmental project ZmapujTo.cz which is intended to fight against illegal waste dumps in the Czech Republic with using geographic information systems (GISs). The smartphone/tablet GIS reporting application ZmapujTo has been developed. This free available mobile application enables to report illegal dumps and also overloaded containers of municipal waste. The project Zmapu...
With the rapid development in Geographic Information Systems (GISs) and their applications, more and more geo-graphical databases have been developed by different vendors. However, data integration and accessing is still a big problem for the development of GIS applications as no interoperability exists among different spatial databases. In this paper we propose a unified approach for spatial d...

If Geographic Information Systems (GISs) contain multiple representations of the same geographic objects at different levels of detail, it becomes necessary to compare the different representations and assess whether they contradict each other or not. Topological information is generally considered first-class geographic information and as such the preservation of topological relations among ob...
[1] We have analyzed the relationship between surface air temperature (SAT), ground surface temperature (GST), and snow cover (SNC) over the terrestrial Northern Hemisphere based on general circulation model (GCM) simulations using GISS modelE forced with the observed SST and radiative forcing changes from 1951–1998. While SAT is the dominant influence on GST during the warm-season, it explains...
