The social, economics and environmental problems that arise by the fast and inadequate occupation of the coastal zones have required faster decisions and belter rational use of the public administration resources. This work shows the utilization of Geographical Information System IDRISI to environmental planning of Rio Grande county, southern Brazil. Based on digital thematic maps of geology, soils, vegetation. urban sites, legal protection areas and previous knowledge about the ecosystem under consideration, the more appropriated areas for agricultural activities, pine and eucalyptus forestry and waste disposal were mapped. The suitable environmental conditions and the technical and/or environmental restrictions were analysed for each item and then modelled in the computer using the analytical tools of the software. Furthermore, the legal protection areas were classified in conservation and preservation categories according to their environmental characteristics. The results demonstrated the potentiality and feasibility of a Geographical Information System as a powerful tool for organi13tion, analysis and decision making on municipal planning.

Police Station

Situbondo Regional Police are law enforcers who work in the East Java Situbondo district. Of course, in carrying out all its duties, it requires communication and information exchange between officers and civilians to carry out police duties properly and effectively. In reality on the ground, not all Situbondo people, especially those outside Situbondo, know the geographical location of the police station in each sub-district in Situbondo district. The only way to find the Situbondo Police Station is to ask and ask someone who has visited or learned about the office. However, using this procedure requires more time and is a bit of a hassle for other people, this is due to the absence of a map pointer to deliver or give an overview of the location of the Police station. From the above problems, namely the absence of loyal Police station appointees at all times to help, it is necessary to design a Situbondo Police Station Geographical Information System that is the answer to the problems discussed above. The establishment of this system is expected to be able to assist the Police in informing the geographical location of the Police station along with important information and also assisting the public in finding the Police station quickly and effectively.

Groundwater is imperative for the continuance of life and sustainability of ecosystem. Contamination of the water is the well-recognized danger to the public health in Pakistan. Hence, this study was conducted to assess and map the spatial variation of groundwater quality in the surroundings of Dijkot Branch Drain by using the Geographical Information System(GIS). For this purpose, sixty samples of groundwater, ten samples of wastewater and five samples of sludge were collected along with their coordinates from the study area. The collected samples were analyzed for chemical parameters and heavy metals, such as pH, EC, TDS, Carbonates, Bicarbonates, Arsenic, Lead, Chromium, Cadmium, Zinc. The results obtained from the study were compared with WHO guidelines. Then, the values of these water quality parameters were mapped by using GIS software. Arc GIS V 10.2 was used for raster interpolation. To exhibit the spatial variation of groundwater quality scenario of the study area, Kriging method was adopted. on. It was generally observed that none of the parameters in the wastewater samples was found to be within the permissible limit. The research study resulted that the groundwater of the study area is deteriorated by Dijkot Branch Drain and is not fit for drinking purpose.

Este artigo visa apresentar o recorte da pesquisa de mestrado sobre a identificação de espaços livres potenciais para a implantação de praças e parques urbanos da cidade média de Santa Maria (Rio Grande do Sul, Brasil). Através do uso de ferramentas de um Sistema de Coordenadas Geográficas, a análise sistêmica de geodados espaciais (cartográficos) e alfanuméricos (tabulares) é utilizada para analisar a espacialização e cruzamento de parâmetros ambientais, de equipamentos comunitários e de informações socioeconômicas existentes na cidade. A partir do cruzamento de informações sobre os raios de atendimento de praças e parques com dados de população e renda, pode-se delimitar onde existem déficits de áreas de lazer e recreação na cidade. A análise dos resultados permite avançar em uma proposta geral de diretrizes que devem estar de acordo com as deficiências, condicionantes e potencialidades de cada região de Santa Maria, a fim de que esses equipamentos sejam implantados no futuro por meio de estratégias urbanísticas e que sejam preservados a partir de um eficiente sistema de gestão e manutenção.

Urban And Environmental Planning

In Geographical information system (GIS), the management of geographic objects is very important, especially not only for urban and environmental planning, but also for any application in a rural environment. In other hand, in GIS, there are different relationships between geographic objects, such as topological, projective, metric, etc. for topological relations, if the scale of the map is changed and if some geographic objects are generalized, not only the shapes of those objects will change, but also their topological relations can vary according to scale. In addition, a mathematical framework which models the variety of this category of relationships does not exist. In the first part of this paper, a new topology is presented based on rectangular ribbons which are defined through a longish rectangle; so, a narrow rectangular ribbon will become a line and then will disappear. In this paper, the different components of this mathematical framework are discussed, as the evolution of geographic objects according the scale. For each case, some assertions are defined which formulate the transformation of the topological relationships into other ones, when downscaling. To conclude this paper, after having proposed an algorithm of displacement to maintain some topological relationships, an experimental example is discussed.
