However, conducting field studies to gauge soil erosion potential are expensive and take a long time, leading many experts in the use of empirical models. Aiming at the development of techniques for the assessment of soil erosion potential in the upper and middle course of the Macaé river basin - RJ, this paper proposes to formulate a mathematical model based on the concept of fuzzy sets and fuzzy logic using a Geographic Information System. The proposed model explores cause-effect relationships on the basis of the general knowledge about causes and the specific relation between processes and indicators of soil erosion which, in the present study, the application of fuzzy-based model was made by combining ten parameters: wetness index , aspect of slope, field capacity, hydraulic conductivity, average annual rainfall, vegetation cover, slope, surface curvature, bulk density and soil porosity, which were aggregated into four linguistic variables sets: (i) Soil Moisture Potential; (ii) Runoff Potential; (iii) Transport Capacity and (iv) Soil Erosion Potential. The final product of the model indicates regions that gather more or less factors promoting erosion and thus related to the input data used and is therefore a valuable tool for decision making in the development of plans and programs for prevention and control.

The present master dissertation applies software engineering techniques in the context of E-FOTO project which offers a free GNU/GPL educational Digital Photogrammetric Workstation (DPW) for computer assisted education in cartographic engineering. In this work, the Unified Process (UP) and Unified Model Language (UML) were applied for the production of conceptual models, encompassing a representative part of the knowledge in such scientific field. The result of such work derived three distinct conceptual models, so-called, Pure UML, Aspect UML and Design Patterns. The models were compared in order to get an answer for the question: Among these approaches, which one is the most compatible to scientific projects like E-FOTO? The comparison was supported by the function point analysis. The outcomes indicate Design Patterns as the approach to be used in scientific projects similar to E-FOTO. Thus, in future works, the Design Patterns conceptual model will be employed for the physical model derivation and its implementation.

The discovery and exploitation of oil in the Campos Basin in 1974 made the municipality of Macaé (RJ) suffered profound changes in its spatial configuration, accompanied by accelerated growth and population density. The aim of this research is to develop application supported by a Geographic Information System, enabling dynamic thematic mapping with main focus on multi-temporal accompaniment of urban growth, located in the coastal zone of the municipality and its vicinity by using a series of historical images, composed of seven times, for the years 1956, 1966, 1976, 1989, 1999, 2001 and 2004. Thus, it was done digital processing of aerial photography and Quickbird system images, in order to validate the potential of SPRING, with operation guided through the steps of segmentation and supervised classification, obtaining results for the growth of the urban area council, within a period of 48 years approximately. SPRING is presented as an important tool in this process, with potential use in studies relevant to the management of cities. So, it was observed the possibility of effective implementation in stages of preparation of the master plan items and activities related to executive projects, both in its planning, and in its implementation.

Autor: Luzardo, Antonio José Rocha Primeiro orientador: Azevedo, Luiz Henrique Aguiar de Abstract: This work proposes the application of Geomatics in support to actions of fast response to environmental emergencies derived from incidents in transportation of dangerous goods on Brazilian roadways. The national cargo transportation network utilizes, mainly, the road modal, which responds for aproximately 60% of the total volume transported. Following this modal utilization, the majority of dangerous goods flows through the roads as well. Despite the use of all safety procedures in the packing and handling stages of dangerous goods transport operations, there is always the possibility of incidents, specially in trips from origins to final destinations. This possibility or, in other words, this potential threat, obviously gives rise to risks to the integrity of assets and health of communities located alongside the roads. In addition to that, environmental risks also arise in the form of contamination of the soil, the air and the surface and underground water. This work, by integrating technological resources, such as Remote Sensing, Global Positioning System (GPS), and Geoprocessing, suggests the implantation of a georreferenced information system, which provides the elements needed for actions of fast response to these events. The proposed system, termed the Territorial Information Bureau, has a structure built to solve problems related with the positioning of sites on the earth surface. It integrates the Geomatics concepts through the application of its four basic stages: data collection, data analysis, information distribution and information use. Thus, complying with the mobility principle, the system still aims at displaying on laptop screen the necessary information for the planning and the execution of actions of response to these events, at the shortest time possible. On the other hand, considering that the Bureau provides, through an Internet connection, the necessary information to those organizations involved in the actions of response to road incidents, it is expected a maximization of benefits of the planning of the preventive and corrective actions of response, as well as a minimization of the effects of such events on the population, assets and the environment.
