The objective of this paper is the elaboration and implementation of procedures in a cartographic representation related by fundamental of thematic cartography and graphic semiology for the standardization of the Environmental Oil Spill Sensitivity Maps supported by a Geographic Information Systems (GIS) for handling and modeling of a large number of variables. These make up the Environmental Sensitivity Atlas to Oil Spills in Coastal Paulista, and that represents the phenomena that occur in geographic space accurately so as to highlight the importance of each element in the evaluation and protection of areas of greater sensitivity oil. The composition of the cartographic documents considers the Littoral Sensitivity Index (LSI), biological resources and the resources for human use that could be negatively impacted. Thus, the information contained in each map was carefully evaluated before implementation, so that the cartographic representations of various resources, environments, and other ISLs, the reader should issue an immediate message that could be understood clearly, without requiring prior knowledge of specialized. Another aspect was the distribution harmoniously all the elements contained in the document, so that information could be enough without overwhelming it. It was also taken a certain care, so each symbol could be used properly in order that there is no conflict in the information.

Understanding the linkages between the natural elements is essential for being promoted the land use, occupation and sustainable management of environmental systems. Universal Soil Loss Equation (USLE), as a predictive model of erosion, is important to allowing the prevention of possible environmental impacts which may drastically interfere in natural or anthropic environments, as well as prevent potential financial wastes and even contribute to greater efficiency of agricultural production. This research will be working some USLE parameters, emphasizing topographic factor from Ribeirão Monjolo Grande watershed. Among the factors considered by the USLE, the Topographic Factor interferes directly in the erosive dynamic of a watershed because it involves variables related to hydrological processes that occur on it. In this research, were discussed different methods for obtaining the Topographic Factor (BERTONI e LOMBARDI NETO, 1985; MOORE e BURCH, 1986; DESMET E GOVERS, 1996) in GIS environment. After comparison between the methods, was indicated that best represents the conditions of geometry strand of the study area. Finally, other factors (R, K, C, P) considered by the USLE were obtained. The attainment of these parameters were guided by the use of geotechnologies, especially in Geographic Information Systems (GIS), with the assistance of secondary data and periodic field visits. The results obtained contributed to the understanding of hydrosedimentological dynamic in this area and serve as a viable strategy for studies of soil loss, aiming at developing consistent material for future researches about environmental planning and land management

The Jararaca River Basin suffers significative environmental impacts caused by inaccurate land use. In Brazil, the areas for permanent preservation are defined and protected by the 2012 Federal Law 12.651. These areas are located in the bank side and other specific places. The objective of this paper was to analyze the results of possible alternatives in function of different procedures used in the proposal elaboration. The methodology used was the elaboration of a priority map for the recovery of these areas using the Geographic Information System with multicriterial analyses and comparing it with the guidelines from the Jararaca River Basin Management Plan. As a result, there were identified differences in the priorities defined by technical issues from the priorities defined by public consultation process.

The understanding of the geo-morphological characteristics allows the identification of flood areas and instability slopes among others important features for land use planning. The study of the hydrological net and the analysis of morphometric parameters help in the geomorphologic characterization, providing specific physics indicators that quantify the risks for environmental damages. The present work used Geographic Information Systems (GIS) and carried out the morphometric analysis of two watersheds in the Alto Rio Sorocaba, municipality of Ibiuna (SP). Using digitalized topographic bases in the scale 1:50,000, the main morphometric parameters were extracted and the Digital Elevation Model (DEM) was obtained. Hence the slope, ground illumination, hill orientation and relief feature maps were elaborated. The characteristics for the two watersheds were quite similar, both have low risks for floods and landslides. Therefore, the concave feature is the predominant hill shape for both watersheds. The morphometric parameters directly related to the river density of the watersheds showed some differences, because the Sorocabuçú watershed presents higher value, resulting in a higher level of relief development. Thus, with this characterization it is possible to provide subsidies for environmental planning actions to the area.

The objective of this paper is to show the development of a Geographic Information System (SIG) for the management of the Educational Centers of the city of Bauru. Currently, the Educational Centers and Assistance Institutes, public or private, in Brazilian cities have some problems, for example: they have no money to manage their institutions and they have no correct form to organize and to store the information. Because of these problems, we developed a system which will manage some informations for these institutions and local authority. This system will allow visualizing the data in the internet by the community. This pilot project has used the softwares SPRING 4.1 e SPRINGWEB 3.0.

The aim of this work is to advance a new approach for estimating demographic density, through combining a Geographic Information System with GMDH Neural Networks. The model that is suggested parts the analyzed space into a rectangular grid formed by multiple cells measuring 0.01 km2 each. The forecasts are elaborated based on the demographic density in each cell and in its neighboring cells at a given time. Despite the limited availability of data during the modeling phase, the utilization of this method for studying a Brazilian medium-sized city presented promising results.

The study presents the application of an ergonomic method based on graphical mesh, created to analyze the attributes of public open space and that influence on their usability. It was based on DePAN method, created to classify the service level offered by niches present in open relationship spaces. However, this method adopted Geographical Information System (GIS ) to make maps that represent the space attributes. This study proposed an adaptation of this method, which replaces GIS by AutoCAD software to generate maps . The goal is to test the feasibility and efficiency of producing maps in AutoCAD software to represent the service niches level. An relashionship area on a college campus for data collecting in graphical meshes and maps confection. By applying the graphical mesh the attributes of that space were evaluated to help promote people permanence on site. Although the process through AutoCAD seems to be harder by being mechanical it guarantees a satisfactory result for analysis, resembling images generated by GIS. Therefore, it is concluded that it’s possible to represent graphically the riches service level.
