In the contemporary cartography modelling of complex features’ distribution using the symbols or choropleth methods leads very often to discordance between the scale of background and the scale of main map’s content. Two kinds of accuracy are distinguished: geometrical and statistical. In the paper the unification of both above mentioned scales has been proposed according to the rudimental rule of coherent visual perception of pictorial model of “reality” characterising the system of coding used in cartography.
The article, being one of the effects of the work as part of a project of the Institute of Spatial Development concerning participation in land use planning together with visualisation, provides documentation of the state of knowledge in this respect. A combination of digital three-dimensional displaying of existing and planned elements and GIS is the most technologically developed form of visualisation in land use planning, especially with respect to cities. Nowadays, many cities use for the purpose of management three-dimensional models which enable it to exchange information about current and planned state in many areas, among others, with respect to infrastructure, safety and visualization of planned undertakings. Three-dimensional models are becoming increasingly popular because of the advancement of the technologies of effective acquisition of spatial data. However, this poses new challenges, such as the problem of determining the ownership of data which is difficult to be established explicitly in case of linking and overlapping information from various sources. Great analytical abilities also cause a problem of complying with the requirements of public safety and defence, since universally available data can become a tool for criminal actions. Compatibility of data is another issue. So that the form of model elements would be cohesive and enable it to freely exchange data, standards of the record of ISO/IEC files were established. Applications which aim at improvement of the possibilities of intercommunication and discussing projects and plans seem to be a natural consequence of the existence of the tool of digital visualization. A three-dimensional presentation can turn out to be more legible for recipients, facilitating public participation in a land use planning process. However, for this purpose, it must be included into the system of planning and public consultations. In this article, first pilot attempts to apply the three-dimensional visualization in public consultations carried out in Holland, in Denmark and in Poland are described. Research conducted on the suitability of visualisation with different degree of realism for town-and-country planning with the public participation was also described. One of the experiments was to apply a method which combines a technique of scenarios of development directions, photorealistic visualisation and public participation. During a discussion with the residents of the small town of Kravlund, a future possible policy of developing the town in different variants was being considered; in the variant of a function of intensive farming, tourism and recreation, natural and of a function of residential housing industry. The discussion was accompanied by prepared photomontages which turned out to be helpful in the debate and they enabled all the participants to better understand the ideas contained in diversified versions the plan [Tress, 2002]. The program of the European-Union Interregional Cooperation INTER-REG IIIC, as a part of the project Public Participation in Spatial Planning in Europe was carried out, gave more experience in the field discussed in this article. One of the tasks directed in Poland by the Mazovian Bureau of Regional Planning provided for an advanced form of the presentation of development plans on the Internet and a possibility of expressing remarks by inhabitants and other interested persons. The Internet comments could assume not only a text form, but also a graphical one. The tool was used for the presentation of the plan and its effects on the prognosis of changes in the environment. The attempt was assessed as successful, because of a non-confrontational course of the discussion. What makes a wider application of a similar method limited, according to the authors of the project, is heavy costs of its implementation. In the Office of Development of Gdańsk, a Study of Localization of Multi-storey Buildings was drawn up. It takes into account the method of presentation of planned investment projects and conducting a public discussion on proposals of planning solutions concerning multi-storey buildings in the area of the city. The procedure is connected with the spatial planning system functioning in this country. A few attempted efforts to use digital techniques of modelling and visualisation proved that the tools of this kind could improve the conditions of a discussion and public participation. These attempts have been of a pilot character so far which results from the lack of formal requirements concerning the form of a presentation of plans and projects during a public discussion. However, entities responsible for projects can come to a conclusion that using digital visualisation will be beneficial for them and decide to use a solution of this type. The authors emphasize the fact that high costs of the studies should be taken into account. The examples presented in the article prove that the costs incurred were beneficial in terms of increased interest and public participation.
Meteorological hazard maps are one of the components of the IT System for Country Protection against extreme hazards (ISOK) created by a consortium of Polish institutions, including the Institute of Meteorology and Water Management – National Research Institute. These maps present meteorological phenomena such as: temperature extremes, heavy and flood-producing rainfall, strong winds, intensive snowfall, fogs, glaze, rime and thunderstorms with hail. These elements were chosen arbitrarily due to recorded or estimated losses. The main aim of the maps is to present visualization methods of hazard forecast with consideration of climatological (historical) background. To identify areas especially exposed to the above meteorological hazards, extensive climatological analyses were performed, based on long-term daily data (mainly the 1951-2010 period). The main component of the warning system is a set of prediction maps created automatically on the basis of scientific algorithms that provide the probability of the occurrence of particular phenomena, or the conditions favourable for them. The algorithms’ structure, based on information about physical processes in the atmosphere, as well as detailed climatological analysis, enables the reclassification of the forecast values – predicted by the ALADIN mesoscale atmospheric model – into four groups of any hazard at the gridded points. Finally, the information will be interpolated and will result in the production of maps of spatial distribution presenting the objective probability of a particular hazard, i.e. its actual risk. Results of historical analysis are to be presented for the public by a number of climatological maps, and accompanied by additional fact sheets to provide society with an actual view of the spatial distribution of the distinguished weather phenomena, and the interrelated risks.
The analysis of visualization in the system of the automated planning of constructions is resulted in the article. The new going is offered near realization of algorithms of visualization of results of calculations within the framework of complex «MIRELA +».
There is a great variety of techniques for complete neurone visualization currently available. Each of them has some advantages and disadvantages. The selection one of them depends upon the requirements of the situation. One of the most useful techniques for observing individual neurones has been the Golgi method with its variations. This method has been extended from the light microscopic to the ultrastructural level. The correlation of neural structure and function was advanced with the technique of intracellular injection of the fluorescent dyes. Investigations of the cross-correlations between morphology, electrophysiology and immunohistochemistry of neurones have significantly advanced current knowledge of the complex organization of at least some parts of the nervous system. Some crucial parameters including the selection of the dyes, the injection technique and tissue processing as well as the appropriate immunohistochemical fluorescent markers are discussed. Cell reconstruction techniques also are mentioned.
Embedment-free electron microscopy (EFEM) is a new method which allows the visualisation of cytoskeleton in whole-mounted cells. In this study we employed EFEM to investigate the structure of cellular scaffolds in glioma C6 cell line. The cells were extracted with Triton X-100 that dissolves phospholipids in the membranes and removes most of cytoplasmic soluble proteins. The DNA and nuclear histones were removed with DNase I and high-salt buffer, respectively. The remaining cellular frameworks were temporary embedded in diethylene glycol distearate (DGD), sectioned and observed in transmission and scanning electron microscope after the removal of DGD. The predominant structure was the extensive meshwork of 10-20 nm filaments in the cytoplasm (cytomatrix) and 15-30 nm filaments in the nucleus (nuclear matrix). The 5 nm filaments, presumably corresponding to the actin filaments, were present in the cytomatrix, but not in the nuclear matrix. Moreover, the ultrathin (3 nm) filaments, connecting other cytoskeletal components were detected. Those are possibly identical with the previously described plectin filaments. For the first time we report the occurrence of ultrathin filaments in the nuclear matrix. Thus, in a addition to the well known cytoskeletal components (microtubules, intermediate filaments, actin microfilaments) EFEM showed a new type of filaments (the ultrathin filaments) in the cytomatrix and nuclear matrix. Further immunocytochemical studies are needed to determine the biochemical identity of the filaments observed in EFEM.
The organization of spindle microtubules (MTs) was examined by light microscopy in mitotic cells of Luzula luzuloides, a plant with holokinetic chromosomes. Allium cepa cells were used as comparative material. Spindle structure and mitotic chromosomes were studied using phase-contrast microscopy and confocal laser scanning microscopy (CLSM) following anti-α-tubulin labeling and propidium iodide staining. The mitotic chromosomes of Luzula were rod-shaped and approximately similar in length, and did not possess primary constrictions. Luzula chromosomes untreated with saturated solution of α-bromonaphthalene, aligned in the metaphase plate, could not be observed as individuals. Their anaphase movement was specific; the spindle attachment was not localized but evenly distributed along the poleward edge of the chromosomes so that the chromatids moved apart in parallel, not forming the classical V-shaped figures characteristic of monokinetic chromosomes. The spindle of Luzula was relatively short with distinct blunt poleward ends. Microtubules were equally spread through the metaphase plate, indicating the holokinetic nature of Luzula chromosomes.
Celem badań była ocena możliwości analizy przestrzennej w zakresie stanu technicznego urządzeń melioracyjnych na terenach użytkowanych rolniczo. Przedstawiono sposoby lokalizacji i pomiaru tych urządzeń oraz ich otoczenia. Przebadano ten proces z wykorzystaniem technologii GIS (System Informacji Geograficznej) - skomputeryzowane techniki systemu informacji geograficznej, włączając w to odwzorowania lotnicze i satelitarne. Wizualizacja danych działki ewidencyjnej na monitorze dostarczy kontrolerowi danych informacji na temat jej geometrii, sąsiadujących działek ewidencyjnych, umożliwi pomiar powierzchni kwalifikujących się do oceny oraz wyłączonych z powodu innego niż rolnicze wykorzystania części lub całości działki. Dane gromadzone w systemie informatycznym ZSZiK stanowią ważne narzędzie monitorowania sektora rolnego. Mogą dostarczać informację z dokładnością do pojedynczej działki ewidencyjnej położonej na obszarach zagrożonych. Scentralizowanie danych w systemie ZSZiK pozwala na wyselekcjonowanie obszarów w strefach specjalnych, szczególnie narażonych na różnego rodzaju niebezpieczeństwa. Przypuszczalnie monitorowanie zmian infrastruktury technicznej na terenach rolniczych poprzez komputerowy system ZSZiK znacznie obniżyłoby koszty obsługi dyrektyw UE i krajowych. Dane graficzne w systemie mogą efektywnie wspomagać proces wyjaśnień rozbieżności powstałych w wyniku przeprowadzonych kontroli stanu technicznego urządzeń melioracyjnych. Możliwe jest prowadzenie różnych analiz z wykorzystaniem atrybutów dostępnych w bazach danych, a ich wyniki oraz prezentacja stanowią doskonałe narzędzie dla jednostek badawczych do sprawozdawczości i prognozowania. Scentralizowanie danych w systemie ZSZiK pozwala na wyselekcjonowanie obszarów i urządzeń melioracyjnych położonych w strefach specjalnych lub wskazanie obszarów, na których występuje zagrożenie.
