13. Manual de utilização das principais funções do programa computacional ArcView 3.2 no apoio à agricultura de precisão.
ABSTRACT: As the Precision Agriculture (PA) concepts consider that the agricultural fields are heterogeneous and need to be managed accouting for spatial variability, the soil fertility, crop yield and pest maps have to be generated by using specific softwares for data gathering and analysis. In this type of data, the geographical positions are crucial. Nowa

14. Reclassificação de polígonos no formato vetorial.
O processo de reclassificação (agregação ou desagregação) é necessário quando se quer gerar um novo mapa a partir de um já existente. Aqui não se trata de dados na forma matricial, mas de dados vetoriais exigidos para elaboração de mapas temáticos com certa precisão cartográfica, onde os contornos precisam possuir a foram de linha. Sendo assim

15. Mapeamento de unidades experimentais com GPS: caso de estudo da Embrapa Cerrados.
ABSTRACT: The major objective of this work was to map the research units and the infrastructure available in the Embrapa Cerrados experimental farm in Planaltina, Federal District. More than 190 identities were observed and mapped through the use of GPS portable receiver with an accuracy of about five meters. The UTM coordinates obtained by the GPS were stor

16. Balanço hídrico na bacia do Jaguaribe, Ceará, utilizando evapotranspiração de referência Penman-Monteith FAO estimada com dados mínimos.
Os dados básicos para estimar a evapotranspiração de referência de Penman-Monteith FAO (EToPM) são: temperaturas máxima e mínima, pressão de vapor real ou atual, radiação líquida e velocidade do vento, muitas vezes indisponíveis por requererem estações meteorológicas específicas. O objetivo deste trabalho foi avaliar a adequação do método

17. Zoneamento geotécnico com base em krigagem ordinária e equações multiquádricas: barragem de Itaipu / Geotechnical zoning based in ordinary kriging and multiquadric equations: Itaipu Hydroelectric Power Plant
This thesis presents a study based on the zoning of geotechnical parameters resulting from core boring, carried out in the basaltic bedrock located in the area of the Itaipu Hydroelectric Power Plant (Foz do Iguaçu - PR). These zonings were carried out based on the interpolation of the data by means of ordinary kriging and multiquadric equations. The data p

18. A geoprocessing approach for studying and controlling schistosomiasis in the state of Minas Gerais, Brazil
Geographical information systems (GIS) are tools that have been recently tested for improving our understanding of the spatial distribution of disease. The objective of this paper was to further develop the GIS technology to model and control schistosomiasis using environmental, social, biological and remote-sensing variables. A final regression model (R² =

20. Sistema de Informações Geográficas destinado ao planejamento da atividade apícola no assentamento Padre Josimo Tavares- PA / Geografic Information System for the planning of the apicultural activity in Padre Josimo Tavares Settlement - PA
Today, apiculture is economically exploited by the man in the pollination of crops, as well as the production of propolis, royal jelly, bee venom and the best known and exploited by the man, the honey. Apiculture has been established as one of the most important activity in terms of economic, social and environmental, once employing family labor-intensive an

22. Caracterização e diagnóstico ambiental das zonas de amortecimento de áreas naturais legalmente protegidas. Estudo de caso : Estação Ecológica de São Carlos e Estação Ecológica de Itirapina
The analysis of the economic development activities in the buffer zone of legally protected natural areas contribute to the identification of elements that answer about the functionality, the contradictions and the limits of the landscape human activities, and ultimately, reflect about the interrelationship between society and environment. In this context th

23. Mapeamento do risco de malaria utilizando variáveis ambientais e antrópicas
Despite much research in the identification of areas with malaria, it is urgent to further investigate mapping techniques to achieve better approaches in strategies to prevent, mitigate, and eradicate the mosquito and the illness eventually. By using spatial distributed modeling techniques with Geographical Information Systems (GIS), the study proposes metho

24. USE OF INFORMATION SYSTEMS GEOGRAPHICAL SYSTEMS IN OPERATION SUPPLY / USO DE SISTEMAS DE INFORMAÇÕES GEOGRÁFICAS NA OPERAÇÃO DE SISTEMAS DISTRIBUIÇÃO DE ÁGUA
Water companies have the duty to provide water to the growing demand, which requires a larger quantity of active connections and, consequently, results in an increase of net extension and a larger volume of produced water. This paper aims at presenting a tool for the support of management of water distribution nets in a pilot area in the city of Goiânia GO.
