1. USE OF USLE/ GIS TECHNOLOGY FOR IDENTIFYING CRITERIA FOR MONITORING SOIL EROSION LOSSES IN AGRICULTURAL AREAS
ABSTRACT The assessment of land use and occupation is essential for predicting soil loss due to water erosion. The objective of this study was to determine criteria for monitoring soil loss in agricultural areas using the Universal Soil Loss Equation (USLE). Soil loss data were intersected with USLE factors and slope using geoprocessing techniques for the Sa

2. Geostatistical Approach for Spatial Interpolation of Meteorological Data
ABSTRACT Meteorological data are used in many studies, especially in planning, disaster management, water resources management, hydrology, agriculture and environment. Analyzing changes in meteorological variables is very important to understand a climate system and minimize the adverse effects of the climate changes. One of the main issues in meteorological

3. QUALITY OF A DIGITAL TERRAIN MODEL FOR SANTA CATARINA STATE
ABSTRACT: Relief characterization using a digital terrain model (DTM) is widely applied in erosion, soil and vegetation modeling. However, factors, such as acquisition technology and the spatial resolution of the digital model, affect modeling results. The aim of this study was to characterize noises in a DTM of the entire state of Santa Catarina recently ma

4. ROLE OF GIS, RFID AND HANDHELD COMPUTERS IN EMERGENCY MANAGEMENT: AN EXPLORATORY CASE STUDY ANALYSIS
This paper underlines the task characteristics of the emergency management life cycle. Moreover, the characteristics of three ubiquitous technologies including RFID, handheld computers and GIS are discussed and further used as a criterion to evaluate their potential for emergency management tasks. Built on a rather loose interpretation of Task-technology Fit

6. The Estrada Real project and endemic diseases: the case of schistosomiasis, geoprocessing and tourism
Geographical Information System (GIS) is a tool that has recently been applied to better understand spatial disease distributions. Using meteorological, social, sanitation, mollusc distribution data and remote sensing variables, this study aimed to further develop the GIS technology by creating a model for the spatial distribution of schistosomiasis and to a

7. 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 =

12. A service-oriented infrastructure for ecological niche modelling. / Uma infraestrutura orientada a serviços para a modelagem de nicho ecológico.
Ecological niche modelling combines environmental data and information about the occurrence of a species to obtain models to describe its probabilistic distribution in a region. Computational algorithms generate models based on the hypothesis that, if a species was found under the conditions which define its niche, then it may survive in any place which offe
