Spatial planning in Poland has got long history. The first significant Act regulating rules of spatial economy in Poland was the Decree of the Polish President from 16 th February 1928 about constructional law and settlements buildings. The successive acts from the range of spatial planning such as the Decree from 2 nd April 1946 about planned state spatial economy, the Act from 31 st January 1961 about spatial planning, the Act from 12 th July 1984 about spatial planning and also the Act from 7 th July 1994 about spatial planning were introducing numerous changes forming ipso facto spatial planning system in Poland. The paper is a revision of recording of the most important acts influencing directly spatial politics on the national, regional ansd also local levels.
SummaryThe article presents the possibilities of using 3D GIS in town planning and urban design, in order to determine the maximum height of the planned development, taking into account the landscape of the modeled area. The increasing speed of the urbanization of valuable natural areas requires strict procedures for determining the parameters of the planned developments, in order to minimise the negative impact of newly designed buildings on the existing landscape. The article presents the procedure for determining the maximum height of newly designed buildings, using the available tools of ArcGIS software. As a result, we have obtained a differential model in the form of a TIN triangle mesh, on the basis of which we are able to determine unequivocally the acceptable height of buildings within the boundary of the given development.
Summary3D visualization is one of the forms of presentation of spatial phenomena, which, thanks to the development of new technologies of acquiring, modeling and providing spatial information, is one of the most popular methods of presenting real objects in the virtual world. Practice shows that 3D visualization is increasingly being used by different entities to present research results in 3D form, thereby ensuring better readability of the papers. The paper describes the methodology of 3D visualization of the influence of atmospheric conditions on wooden facades of a school building. Methods of obtaining data for the purpose of creating a 3D model of a research object, processing vector and raster data, and rendering the final animation were described. The results of the study show that the use of 3D visualization as a form of presenting research results enables accurate estimation of the intensity of atmospheric conditions on the vertical elevation, taking into account the exact geometry of the research object.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
