Analýza znečisťujúcich látok vo vybraných monitorovacích staniciach mesta Košice za obdobie 2008-2010

In general, air quality is determined from the concentrations of pollutants in ambient air. Air quality criteria (limit and target values, margin of tolerances, upper and lower assessment thresholds) are based on the current legislative framework. In Slovakia, the air quality criteria are imposed by Decree No 360/2010 Coll, on air quality, of the Ministry of Environment [1]. In relation to the implemented measurements, it is necessary to choose effective tools needed for the pre-processing and post-processing of overall air quality assessment. The article aims at applying suitable GIS tools in the assessment process of air quality in the Košice agglomeration for the selected period 2008-2010. In the overall assessment of the area in question, the processing of information on emissions declared as particulate matter (PM) was considered in terms of a conservative approach to the assessment of air quality for PM10. For the assessment, the yearbooks and reports on air quality in Slovakia in 2008-2010 of the Slovak Hydrometeorological Institute (SHMI) and professional publications were used.Vo všeobecnosti kvalita ovzdušia je stanovená z obsahu znečisťujúcich látok vo vonkajšom ovzduší. Kritériá kvality ovzdušia (limitné a cieľové hodnoty, medze tolerancie, horné a dolné medze na hodnotenie) vychádzajú z platného legislatívneho rámca. V podmienkach SR kritéria kvality ovzdušia vyplývajú z vyhlášky MŽP SR č. 360/2010 Z.z. o kvalite ovzdušia [1]. V nadväznosti na realizované merania je potrebné zvoliť efektívne nástroje potrebné pre preprocesing a postprocesing procesu plošného hodnotenia kvality ovzdušia. Príspevok si kladie za cieľ aplikovať vhodné nástroje GIS do hodnotiaceho procesu kvality ovzdušia v aglomerácií Košice za vybrané obdobie rokov 2008 - 2010. Pri celkovom zhodnotení predmetnej oblasti bolo uvažované so spracovaním informácií o emisiách deklarovaných ako tuhé znečisťujúce látky (TZL) v zmysle konzervatívneho prístupu k hodnoteniu kvality ovzdušia za PM10. Pre posudzovanie boli použité ročenky a správy pre kvalitu ovzdušia v SR za rok 2008 - 2010 z SHMÚ a odborné publikácie

Alternatives and implication in process of environmental impact assessment

EIA is an interactive, rule-based expert system for the environmental impact assessment. It is designed for a screening level assessment of development projects at a pre-feasibility stage. Typical problems for the evaluation include: resettlement; watershed degradation; encroachment upon precious ecosystems; encroachment on historical/cultural values; watershed erosion; reservoir siltation; impairment of navigation; changes in groundwater hydrology, waterlogging; seepage and evaporation losses; migration of valuable fish species; inundation of mineral resources/forests; other inundation losses and adverse effects. It is important to prevent environmental pollution when carrying out large-scale development projects, such as artificial change of landscapes and building of certain structures that may cause a tremendous impact on the environment. In accordance with Cities Environmental Impact Assessment Departments it is necessary to provide project organisers with a necessary advice and instructions concerning the environmental impact assessment a survey to predict and evaluate environmental impact to be conducted by project organisers. Prior to offering the advice and instructions, cities need to hear the opinions of residents of the areas concerned, mayors of related municipalities and other opinion leaders, including specialists, to reflect their views in the environmental preservation. The first aspect in any quality assessment is to determine the representativeness of data both in terms of physical siting and data collected. It must be recognised the environment is a dynamic fluid; quality therefore varies over space and time. There will be locations in any community that experience poorer quality than recorded at a monitoring station. Likewise other sites will have a better quality. Most communities have only a single monitoring site. Therefore, the air quality monitors are sited to provide a representative estimate of the community exposure to contaminants

Visualisation and analysis of the urban built-up area with VRML

The Virtual Reality Modelling Language (VRML) is a file format for describing interactive 3D objects and worlds. VRML is designed to be used on the Internet, intranets, and local client systems. VRML is also intended to be a universal interchange format for integrated 3D graphics and multimedia. VRML may be used in a variety of application areas such as engineering and scientific visualization, multimedia presentations, entertainment and educational titles, web pages, and shared virtual worlds.VRML is capable of representing static and animated dynamic 3D and multimedia objects with hyperlinks to other media such as text, sounds, movies, and images. VRML browsers, as well as authoring tools for the creation of VRML files, are widely available for many different platforms. VRML supports an extensibility model that allows new dynamic 3D objects to be defined allowing application communities to develop interoperable extensions to the base standard. There are mappings between VRML objects and commonly used 3D application programmer interface (API) features.VRML is useful for a variety of applications, including data visualization , financial analysis, entertainment, education, distributed simulatio, computer-aided design, product marketing, virtual malls, user interfaces to information, scientific visualization.Data visualization turns numbers into a 3D VRML world. It takes a complex database with lots of numerical information and turns it into a three-dimensional environment, which may have a time dimension. Even interactive features and sound can represent information.Financial analysis can use data visualization to visualize financial data, such as stock prices or corporate financial accounts. Anomalies and opportunities can be detected by highlighted areas in the data set.Entertainment is a potential goldmine for VRML developers, since VRML allows for interactive, 3D movies. VRML allows customized, dynamically-generated camera angles with alternate scenarios possible.Education with VRML can give people a chance to learn something in a new way, or learn a real-life job without the dangers of physical machinery.Distributed Simulation can use multi-user VRML worlds over networks to simulate military exercises or industrial courses.Computer-Aided Design is an area where designers could collaborate on designing industrial parts or other 3D objects in a shared multi-user space. Or alternatively, they can e-mail parts back and forth to each other, or put drafts up on Web servers for comments.Product Marketing often tries to reach buyers at an emotional level. VRML is great way to do this, for the same reasons that it will be successful in entertainment applications. In addition, marketers selling 3-dimensional products like clothes can give buyers an impression of the object before they purchase it.As User Interfaces to Information, VRML can help bring some sense to the confusing hypermedia world of the Web, and to massive databases packed with more information than can be easily represented textually.In Scientific Visualization, researchers or students can observe a 3D protein hovering in space and click on parts of it to learn about the function of the parts of the protein through hyperlinks to a database. In fact, Aereal Inc. is currently working on this for the Genetic Information Bank of Japan's Institute of Physical and Chemical Sciences
