Abstract Land pollution due to past mining activities is a major environmental issue in many European countries. The Aljustrel mine (SW Portugal), located the western sector of Iberian Pyrite Belt (IBP) presents negative visual and impact as consequence activity that has developed since Roman era. Its impacts are also restraint on life quality population. exposure pyrite other sulphides air responsible for observed soils, surface water stream sediments. This paper investigates load potential...
This paper aims to compare the results of two techniques Kriging (Ordinary and Indicator Kriging) that are applied estimate Private Motorized (PM) travel mode use (car or motorcycle) in several geographical coordinates non-sampled values concerning variable. The data used was from Origin/Destination Public Transportation Opinion Survey, carried out 2007/2008 at S?o Carlos (SP, Brazil). were region with 110 sample points (households). Initially, Decision Tree probability choice surveyed...
A new statistical approach for preliminary risk evaluation of breakage in tailings dam is presented and illustrated by a case study regarding the Mediterranean region. The objective proposed method to establish an empirical scale risk, from which guidelines prioritizing collection further specific information can be derived. relies on historical database containing, essence, two sets qualitative data: first set concerns variables that are observable before disaster (e.g., type size dam, its...
To carry out a spatial analysis of the occurrence acts violence (specifically robberies) in public transportation, identifying regions greater incidence, using geostatistics, and possible causes with aid multicriteria Geographic Information System.The unit is traffic zone survey named Origem-Destino, carried Salvador, state Bahia, 2013. The robberies recorded by Department Public Security Bahia 2013 were located made compatible limits zones and, later, associated respective centroids. After...
The main objective of this study is to propose a sequential method for spatial interpolation mode choice household locations where choices are unobserved based on Decision Tree analysis and Geostatistics. Initially, was applied in order estimate the probability surveyed households, thus determining numeric variable be estimated by Ordinary Kriging. data used from Origin-Destination Survey Urban Transportation Evaluation Survey, carried out 2007/2008 city São Carlos (São Paulo/Brazil). area...
The process of coastal erosion is a global problem that impacts approximately 70% regions the Earth. It causes loss property, infrastructure, and biodiversity, besides generating major economic impacts. Therefore, analysis monitoring an issue needs to be addressed. In this sense, remote-sensing data have been widely used in studies evaluate spatial temporal changes land use. addition, use time series satellite imagery applied investigation Earth's coverage its spatio-temporal pattern has...
The segment of the Ipueira-Medrado mines constitutes two main chromium operated by Companhia Ferro-ligas da Bahia (Ferbasa). research area is located in municipality Andorinhas, north center state Bahia, Piemonte Norte Do Itapicuru region. Therefore, objective present work use Remote Sensing and Aerogeophysics data to elaborate geological map study highlight new target areas for mineral research. Digital Image Processing (PDI) stage was carried out an environment ENVI® 5.3 software scenes...
O principal objetivo deste trabalho é estimar a produção de viagens por Transporte Coletivo, na hora pico, em pontos não amostrados espacialmente, através da técnica krigagem com deriva externa. Desta forma, as interpolações espaciais são realizadas considerado o par variáveis POPULAÇÃO (variável secundária) X PRODUÇÃO DE VIAGENS primária). Os dados utilizados oriundos Pesquisa Origem-Destino, realizada Região Metropolitana Salvador, Bahia, 1995, e do censo 2010. Com isso, estimação para ano...
Traditional methods for travel demand estimation are often built on socioeconomic and information. The information required to conduct such studies is costly rarely available in developing countries. Besides, some conventional do not consider the spatial relationship of variables and, general, a large amount individual data required. key aim this paper evaluate importance considering when estimating mode choices especially lack data. study area São Paulo Metropolitan Area (Brazil) dataset...
